BIG NOTICE: IM NOT TO BLAME WHEN YOUR DEVICE GOES TO NIRVANA, FIRE, ANGRY WIFES!!!!

Sometime it's done: Before the CPU date, or the disk is full, making the notebook battery limp. No problem, there are spare. But what to do with the old current donors? Simply continue to use.

A defective notebook battery can be reused. Well, maybe not in its original function but with a similar purpose. For example, as a mobile power supply for a Raspberry or as homemade Power Bank. To understand why this works, you have to again lead shortly before eyes, like a notebook battery is constructed. First, there is every battery of several round cells, usually with a voltage of 3.2, 3.6 or 3.7 or 4.2 volts. If a laptop battery is now 9.6 volts, one can assume that here three 3.2-volt cells connected in series. In order to increase the capacity and thus the endurance, several rows are often connected in parallel. So there is a 9.6-volt battery of six 800 mAh cells, ie 2 x one can start from a nominal capacity of 1,600 mAh, 3 batteries in parallel. Now loses a battery significantly to performance, ie state assets, then this often means that only makes a cell slowly limp. In other words: Large parts of the battery are therefore still usable. You just have to use them appropriately.
----
1. Cut the battery pack housing
First, the battery needs to be opened. This works best along the glued seams with a cutter. But careful, otherwise there is a risk to damage the sheathing of cells.
----
2. Open the battery pack housing
If you have the lid removed, the battery cells should openly visible are one.
----
3. Release cells
Now you remove the lower part of the battery housing, so that only the cells and electronics remain. But beware: Danger of short circuit!
----
4. separate cells from one another
Now you separate all the cells from one another, and removes the board with the electronics also.
----
5. identify broken cells
With a measuring detect the weak cell
----
6. Remove the solder tails
Then from the remaining intact cells remove solder tails finally, if you have not already done so.
----
7. obstruct battery cells new
Now you have several options. Either you look procured via Ebay or Amazon a Powerbank-empty enclosure and equipped with the one of the cells. Or you yourself builds a new battery pack. For this one connects in the simplest case, all cells need with tape. We have here two cells so packed that each have a plus and a minus pole are together. On one side is soldered then a bridge across the two poles, for example, from a piece of paper clip or wire.
----
8. Solder new port
On the other side is soldered to two cables, which converge in a connector as needed. We have chosen two pin header, because the both adequate tools for loading by means of the BEC-coupling of a Model-charger as well as for the GPIO pins of Raspberry.
----
9. Battery safe load
Now the package can to the charger. We are initially reluctant to the charging current, slow charging and discharging ensures the medium term for a slight improvement in endurance. Important: The cells of the battery packs usually require a loading protecting electronics. In our case it accepts the charger. The Power Bank enclosures are already equipped accordingly.
----
10. use battery pack
When charging is completed, you can use it with a Raspberry Pi to give him power,for example.
----
THATS ALL, HAVE FUN AND STAY ADDICTED!!!!!!
While this is a cool idea, I made mine out of the atrix webtop. This has an HDMI monitor, keyboard,as well as battery and charging. There are instructions on the net. Some of them conflicting but there is more then one definitive solution so you use what you have. Webtops are available for cheap on the net. I had them from my old atrix phone. Happy hacking.
Hi,
I just want to point out that the Raspberry PI wants its 5V +-5%. Some sources may say that up to 6V is okay but more shouldn't be applied.
So actually you need a voltage regulator to power a PI. You got two choices here:
-A drop down regulator if you use two or more cells in row
-A Step Up regulator if you want to use a single cell or more in parallel
So just make sure the regulator can deliver more than 1A (2A would be better).
Also if you build a LiPo Battery with cells in row always connect a balancer cord. And always use a charger with balancer. Otherwise you will likely destroy your battery.
One way to get this cheap and fast running would be a selfmade powerbank for the above used 18650 LIPOs.
There are also some LIPO shields out there but personally i dont have good experience with these.
Happy Soldering

I got a surprise package to review...when I opened it, it was a Seidio Multi-Function battery charger!!!! First I will say that is a must-have product for ALL HTC Incredible owners. HTC Incredible has proven to have a less powerful battery life than we would all like to see, and so the multi-function charger makes keeping an extra battery a breeze. Now, that is not all... You can also use this multi-function charger if you have a couple of different devices by switching the charging plates....and the USB connection can be used with any USB cord for charging.
The package included:
Base
Battery charging plate
Device charging cable
The features multi-function charger offers are:
Ability to charge an extra battery and your device at the same time
Prongs fold away for easy travel
Additional charging plates can be purchased separately for use with other Smartphones
Travel ready as it uses 100-220v charge
Ease of Use...
Getting everything set up, took me a few minutes and the charger is really easy to use. The USB cord is longer than the stock charger and is softer, which makes it more convenient to use it anywhere. The phone can be charged direct from PC, or the charger, just by plugging in to appropriate sources and switching the AC/USB Power switch. As mentioned above, the multi-function charger can be used with different devices by switching the charging plates, or if you have more than one device. This makes it the most needed item.
Charging Process...
Charging the phone was nice and especially having the extra battery ready is very handy. The charging time for multi-function charger versus the stock charger is a little shorter but not by much...although considering that it charges two batteries at once, yes definitely shorter charging time. The wall charger, at least the one I had, did make a static high pitched noise, but it was not enough to bother me. I have heard other chargers to do that, so I am unsure of the cause.
Few Days Evaluation...
Over a few days of use, I can even further confirm that this is a must have product for smartphone owners which like to use a lot of battery juice. The charger is also very compact making it easy to take along while traveling, as it is small and the prongs completely fold in...which is something Seidio worked on and improved over the past multi-function chargers. Also keep in mind that the interchangeable charging plates is a guarantee for upgrades for newer devices as they come out. I can guarantee that this will be a high demand item.
To purchase the Seidio Multi-Function battery charger, please visit Seidio Online - Multi Function Battery charger.
I have purchased products similar to this, and the prongs that plug into the wall always break. At 30$, its quite expensive... how's the build quality?
I almost bought one before the Dinc came out. They were $19 then. Don't switch out batteries now though, so I'm not sure I would use it. I have a number of retractable MircoUSB cables (one on every computer now) and I carry one so I can charge almost anywhere if needed.
Nope
I continue to maintain that the best way to break those teeny tiny clips holding your Incredible together, is to keep opening and closing it. While my AT&T Tilt had an easy to remove back, the Incredible does not.

Hi,
This charger works with the "BF5X" battery? (MOTOROLA DROID 3)
I've not got the tools to do this but I've came up with a idea which mite work if someone has the right tools, most importantly a 3D printer would be needed to make a tidy job.
Providing Power
Using a 28awg USB cable to power the Note 4, using a 3D printer to copy the battery shape which clips on and adding terminals to the battery which will make contact with the phone terminals. The USB cable would go into the battery block which is made by the 3D printer and the USB cable would be soldered to the terminals on the battery block which would make contact with the phone terminals. So what you would have is a empty battery which is powered by the USB cable, providing power to the phone.
Then the cover would fit nicely over the battery and the USB cable will pass through a hole/slot in the phones cover.
Adding Cooling
Cooling could also be added by using the dummy battery. Finding a heatsink which is smaller then the battery so the heatsink can touch the back of the phone in the battery bay, so the battery would be made like a bumper case around the heatsink. So what you would end up with is a heatsink USB powered battery, so using up above to provide power to the phone, with the printed battery made around the heatsink so the heatsink can actually sit right on the bottom of the battery bay touching the phone and a back cover cut to make the heatsink stick out, with the back cover permanently fitted to the battery/heatsink unit. The cover with its clip would hold the battery/heatsink unit in place securely to the phone. Other smaller heatsink could be fixed and cut through the back cover or a metal plate could be used to line the inside of the back cover which would be fixed to the main heatsink to provide cooling to other parts of the phone. Both could be used, a metal laced cover with additional heatsink attached to the metal plate.
A small fan could also be added to the main heatskin blowing air into it and this could be powered from the same USB lead.
This shouldn't add a huge amount of weight to the device since you are losing the battery cells and the heatsinks are pretty lite weight.
This is only a idea which I quickly came up with, I've not looked fully into the electrical side of this but if the electrical side of this works, then a person with the right tools could pull this off and make a rather nice job of It.
Because I don't have a 3D printer I've not thought any further then the concept of this, you should be able to imagine what it would look like from what I've described but I can draw up the concept if needed. I decided to write on here about my idea in the hope that someone has a 3D printer, so you can make this, test it and even share the 3D printed parts.
It would be great if people got involved with this, with the technical side, adding more to the idea and even making it.
I was thinking in the same direction. I was thinking of making the "battery" out of aluminium and a small group pcb on top for the battery contacts.
Yeah making the battery out of aluminium would be better and easier since a 3D printer wouldn't be needed and all you would need to do is cut a bit of aluminium and cutting a slot out for the PCB terminals to sit in, could even buy a cheap note battery and remove the plastic end strip which houses the terminals on the end of the battery and attach that to the aluminium block with the USB lead going into that. Then a heatsink and phone cover could be fixed/glued to the aluminium block. Would a USB lead going directly into the terminals and plugged into a USB charger/USB port power it or will a PCB need to be made to regulate the power going to the phone? Without testing it I would say the USB lead directly into the terminals, would be okay since the chargers have circuit protection and I think the voltage is the same? I've not properly looked into, so I maybe wrong and more work maybe involved for the power side.
20mm-Aluminium-Heat-Diffusion-Cooling, since I'm a new user it won't let me use links, but that can be found on amazon 98 x 40 x 20mm Aluminium Heat Diffusion Cooling Fin
That heatsink would fit, would need to be cut to fit the terminals but it would be a good heatsink to use and if a small enough fan can be found that can be fitted using screws which fit between the fin's
I tried a cooling fin as suggested - just happened to have one laying around. No effect - device still overheated.
To this point, the only thing which has worked for me is to make small very chilled (not frozen) chillpacks from 4x3 hobby ziplock baggies and ice cube substitute blue goo. Chill it, place it between the back cover and the GVR cover plate and ur good to go for an hour. The problem with using frozen ones is you tend to fog.
Another option would be a small fan. As far as a power source, one that takes a AAA battery. Have not seen anything of the correct size to work.
With this mod the battery would be removed so that in itself will help reduce the heat and the heatsink will be directly touching the back of the phone up close because the heatsink will go right into the back of the phones battery compartment, rather then being stuck onto the battery. Also other additional heatsinks on hot-spots should help reduce the heat, a laptops CPU cooler with the gas filled copper pipes with the fan unit may work well if the phone case can be modded to house the cooling unit and still click down securely, trying to find one which will cover the hot-spots and also to go over the battery bay.
So the aluminium block as the power unit in the battery compartment with the terminals to power the phone and then that being attached to the back cover which has a laptop CPU cooling unit built into it. So we would need to find a cooler which fits reasonably well onto the back off the phone and work out a way to mod/cut the case cover, so the case cover will be used to make it look tidy and also the cover will be used so you can attach the cooler and power supply to the phone.
If using a USB cable to power it the volt will need to be regulated down to 3.8-3.85v to power the phone, I've been looking for a regulator but I can't find one which will bring 5v down to 3.8-3.85v whether anyone on here can come up with a circuit diagram to get the power down to the voltage needed?
I'm going to have a quick look around for laptop CPU coolers which mite fit, if anyone else comes across any, add them here, a laptop cooler fan would definitely fit and could be powered by the incoming/out going power depending on voltage of the fan, also some graphic cards have heatsinks with small fans on but a laptop CPU cooler would ve better since its gas filled and would keep it cooler for longer

I was in the market for a large capacity power bank and really liked the look of this one on Amazon. Shipping was very fast as it was fulfilled and shipped by Amazon. In this review i will go over the Features, First impressions and Final thoughts after using the power bank for some time.
Features:
Ultra-slim design with a hard plastic & aluminum alloy construction
High capacity 20,000mAh
Two USB charging ports (5v-1.0A/ 5v-2.1A)
Micro USB input for charging the power bank (5v-2A)
Blue LED digital charge indicator
Built in over-charge, and short circuit protection
Dimensions: 6.8 x 4.8 x 0.5 inches
Compatible with any USB charged products such as iPod, iPhone, iPad, Android tablets and phones, ETC.
First impressions:
After receiving the power bank the first thing i noticed and was pleased with was the packaging. When you buy a product you expect there to be in professional and quality packaging and they definitely did that with this power bank. After unpacking the power bank and holding it i was very pleased with the aluminum alloy construction. When researching power banks the materials used was one of the main factors for me choosing this one over some of the others on the market and im glad i did, In the hand the build quality and construction feels premium just like my HTC one and iPhone. While it is a slim unit i would not say its the lightest power bank it is after all 20,000mAh capacity which is a larger power bank . If you are interested in smaller lighter package you will also be shrinking the battery capacity so that was something i wasn't willing to compromise on. First thing i noticed during use was the digital LED capacity readout. This is a premium feature that also was a top factor for me choosing this power bank. With a quick slide of your finger across the read out screen you can see exactly the charge you have left, No more relying on the few led lights the other banks have to judge how much juice you have left. Overall my first impressions of the power bank was very positive. Between the premium build quality and features included i was very happy with my choice. Amazon LINK
Final Thoughts:
After using the Power Bank for some time my initial opinion did not change, In fact im not sure how i lasted before without one. The quality of the unit is outstanding, Being constructed from aluminum gives it some serious durability, and looks brand new after heavy use wile camping, traveling, beach trips, and school/ work. The battery capacity is outstanding, as a power user Ive always found myself killing my phone battery far to early in the day and now i always have a charger even wile away from on outlet. Ive also found it very useful for camping trips and power outages due to the large capacity you can charge many items on one single power bank charge which is very handy in those situations. Overall am very pleased with my purchase. Between the stylish build, quality of materials used and the overall charging performance i would recommend this to anyone in the market for a power bank. Amazon LINK
Looks like an advertise. No connections to G2. Are you the seller?

As I thought.. I learned something extra so I figured I would share. if you want to know how much charge is on the Power bank before plugging it in, just pass your finger over the spot where the display is at, and it will turn on the digital display and show you the amount of charge that is still available to you.

This one here is really powerful and nice. I can really recommend it.
I purchased a Choetech T513 on Amazon to charge my Turbo via Qi. Several of the reviewers said they had a Droid Turbo. When I used the device, my phone heated up to 114 degrees, which can't be good. Furthermore, it only charged about 1% every ten minutes or so, regardless of whether I used a normal charger or the quick charger.
Has anyone successfully used a Qi charging pad with this device and had it work without setting the phone into dangerously high heat mode?
As you can see, the Choetech device had great reviews:
http://www.amazon.com/Wireless-Char...&qid=1431549415&sr=8-1&keywords=choetech+t513
I've never charged my phone with USB other then to test it actually worked. I use Qi every night or every other night. I experience almost no warmth during charging at all using a cheapie Qi pad I got off of ebay 2 years ago. I think you tend to get more warmth if the alignment is bad. The charging coil is a little closer to the bottom of the phone then the top so it shouldn't be centered on most charging pads. For this reason I opened my charger up and moved the coil slightly so my phone can sit perfectly centered on the pad. I have had Qi charging issues with a Nexus 7 2013 where it said it was charging but actually wasn't on the same pad. My Moto has never failed to charge perfectly. It takes about 5 hours for a full charge if the phone is at 1%.
I purchased a tylt vu from verizon and am still having trouble. It will recognize the phone, start charging, and then keep reassessing the positioning.
The issue is that I have a magnet on the phone backing that connects to my car harness. I moved that perpendicular to the phone, as close to the lens as possible, and the same problem still occurs. I can't figure out how to make this work. I thought the qi charging was toward the bottom of the device, not the top.
Other than removing the magnet, which doesn't make a lot of sense, how can I make this work? You'd think the magnet would enhance conduction.
I use the nexus 4 wireless orb charger and works flawlessly. Charging time is slower if I have daydreams playing but decent charging speeds when daydreams are turned off.
Sent from my XT1254 using XDA Free mobile app
I got this charging stand off of eBay and it works great, no overheating. Item #161580812967. The only time it will get warm is the occasional time I use the Turbos rapid charger.

I've used qi for my last 2 phones, tends to work really well. I agree with previous posters that the area on the turbo is very small, and almost 2/3 towards the bottom of the phone. If you're not lined up just right, it will stop and start over and over again. try to align it right on spot.
If you notice the charger I listed above has 3 coils and works perfectly.

Exactly. On my Nexus 5, the rear circuit lined up perfectly in the middle of the charging orb. But with the Quark (Droid Turbo/Moto Maxx/Moto Turbo) you have to hang the phone off the end of the orb for it to mate with the charging coil. Seems the Qi circuit in the phone is in the lower third, instead of in the middle (where it should be).
The LG G3 is like that too, so our phones are not alone.
My solution was to get a 3-coil charger, aka triple coil charger. Get them on Amazon for $22 - $28 with free shipping. Flat or tilt type, either design works perfectly with the phone, IF it's a triple coil charger.

Yes, it does. No matter where you place the phone on the charger it will hit charging coil, as it has 3 integrated all across the design, instead of just one coil.
I own both the flat and tilt 3-coil charging pads, and I like the tilt a little better as I can see display for notifications easy without having to pick up the phone.
Introduction
The Presto is a 12000mA/h portable battery charger. Much like the included wall charger, it too is Qualcomm QuickCharge 3.0 compatible. Unfortunately, my Nexus 5X is not QuickCharge compatible, but is still capable of pulling 3000mAh from the charger provided from LG. Due to the size of the battery built into my phone, this charger can fully charge my phone three to four times before running out of juice. Impressive for such a small package.
Disclaimer: I received the reviewed products from Tronsmart in exchange for this review. I have no financial stake or affiliation with this company. No bias exists here.
Details
Device: Tronsmart Presto 12000mAh USB Type-C External Battery Power Bank
Price: $34.99 (at the time of this review)
USB-C Input/Output: 5V/3A(MAX)
USB-A (QC 3.0) Output: 3.6V-6.5V/3.0A,6.5V-9V/2.0A,9V-12V/1.5A(MAX)

Initial Impressions
Upon opening the package I discovered I had been shipped a Single Port Qualcomm QuickCharge 3.0 charger, a short USB-A to USB-C cable to charge the power bank, a very nice braided USB-A to USB-C cable and, the star of this review, the Tronsmart Presto.

The wall charger, battery/portable charger and cable are consistent with the quality that I've come to expect from Tronsmart. For the purpose of this review, I'll only concentrate on the look and feel of the Presto external charger.
Design and Features
The Presto is a sleek rectangular brick measuring 6.25" Long, 2.125" Wide and .75" High. The entire brick, with exception of the top trim, is a nice feeling black matte plastic. The trim is a glossy black plastic as well as the "Tronsmart" branding which is debossed in the center. Overall, the product feels well built, slick and would be reasonable enough to carry in something as small as a woman's purse. My only complaint about the design of this device is that Tronsmart made the odd choice to label both charging ports with black ink instead of white. The labels aren't legible except when catching the light at a certain angle. An interesting decision, especially when you consider the included charger has white labels.
This portable charger comes with two ports. A USB-A QC 3.0 compatible port that is strictly used for charging and a USB-C port that is used to charge the brick and can also be used to charge USB-C devices. To enable charging, one must simply connect a device and then press the power button on the side of the Presto. Four charging lights will illuminate and as the external charger's power is drawn down, these lights will slowly fade one by one. It works the opposite way when charging it back up. Four lights indicates that the Presto is fully charged.
Performance
Charging performance is terrific. I was able to achieve charging speeds identical to the 3000mAh charger that came with my phone, although, normally, my phone pulls about 1800mAh due to several factors like battery temperature and CPU usage.
I was unable, however to match the same performance when connected to the QC 3.0 port via a USB-A to USB-C cable. This was expected, however, as the phone, as I stated before, is not QC compatible.
(hadn't changed the theme before this screenshot)
Overall
Overall, the Presto is a sleek, minimalistic, easy to carry portable charging solution that can come through for charging many different devices in a pinch. Even though my phone is unable to take advantage of the QuickCharge 3.0 capabilities offered up by this product, charging speeds via the USB-C port are still impressive.
Additionally, I'd like to thank Tronsmart for the charger, cables, the power bank and the opportunity to review one of their products.
