Home made battery for XDA

I've been having a helluva time with the new (internal) batteries available in the market ever since the original Furukawa battery died - the new batteries dont seem to be able to hold charge as well as the original one.
I was wondering whether it would make sense to connect two original nokia batteries (the bl5 looks thin enough) in parallel and connect them to the XDA using the same circuit board that's attached to the furukawa.
(If this works, the battery would maybe even provide more power than the original one!)
Anyone know if this would work?
The nokia battries are about 800mAH each, so if I connect them in parallel, would that raise the rating to 1600mAH?
Cheers

delayed answer but.. still...
Having an OLD battery on my thing... I'm also considering a "home made battery". Yes, it can be done.... I see no major problems. But remember that a battery = battery + protection circuit. If you put them in paralel, I guess it would be a better idea to strip the two nokia batteries from the protection circuit and use only the ORIGINAL one....
But this is still theory, I didn't tried it yet. But, I'm considering.
The best solution would be in finding a BIG flat battery, not connecting two in paralel.....

If the batteries have the same voltage, and you still have your old one, you could open up all 3 and replace the cells from the nokia with the old cells. The use some shrinkwrap or tape to cever the old on up and plug it back in. As long as the voltages are the same (and they should be if you swap just the cells) then yes you'll have a much higher capacity battery to play with.

Is Battery Conditioning Necessary? Can I just plug in any time?

Greets,
As we have all probably learned, the Tilt EATS batteries; especially if you use Bluetooth or GPS.
I would like to just plug in my Tilt every morning when I arrive at work. However, I am concerned that I might hurt the batteries ability to hold a full charge, etc.
Based on other threads, when i got the phone, I immediately let it run down (rather than charging), and have had 4 or 5 complete drains (where it shuts itself off) before charging. I find starting up TomTom is a great way to get it to drain off.
Does anyone know if I can just plug it in every morning, regardless of the battery charge?
Thanks!

LiIon/LiPolymer batteries don't have memory effects and do not require conditioning. In fact, if you're using them you'll extend their life by keeping them topped off. Plug in whenever you like.

aye PerfAlbion is right - the downside is you lose some capacity over time no matter what you do - tradeoff of the technology im afraid

And actually, you have been hurting your battery letting it run down so many times. It's never a good idea to let it run down fully till the point when it shuts off.
Usually, a recondition is needed only after 3 months just so that the software remains caliberated with the battery and displays the correct charge.
Otherwise, the more you keep it plugged in, the better your battery will be.

Totally agree.
I got into the routine with back my Wizard of pluging the charger in every night. You never know when you may not have chance to top up!
Its my morning alarm clock also!

Does anybody know if you can get batteries for the kaiser/tilt that holds more charge?
Mine says 1350mAh. Can you get more than that?
Thanks,
Sebastian

Not sure but would be nice to know...
At this moment I carry a 'Power monkey' as a bckup supply in my case just for emergencies.

There are some extended batteries shipping, but I'm a bit wary. To increase charge density for these types of batteries, you have to increase their physical size. So unless the battery pack supplied has dead space in it, you'll likely have to replace the back on your phone to add significant capacity. I haven't seen any with that warning or sold with a replacement back.

Hmm yeah you are right! just have to keep it topped up guys or carry a 3rd party charger with you.
Still... never depleted it yet, but who knows!!

Hi Farsquidge!
I know I can search... but.... may I ask where you bought your Power Monkey from ?
I saw some on Maplin's site but seem to have the wriong connector.
Off to search some more !

Personally, I just purchased a second battery and carry it with me in my laptop bag. The only time I've ever needed it is when I'm flying and using the phone for music/movies. And since it's "official" HTC gear, I never have to sweat a warranty replacement for the phone by using unapproved equipment.
But when I turn off 3G (which is always off unless I'm tethered/surfing), I'm getting between 8-12 hours on a charge with some decent usage. The one problem I had was the day with about 6 hours of phone calls.

there are standard size 1650 mAh batteries. Larger than that and they are not standard size and come with a new back panel to accommodate the added size.
There are a few threads in the "Kaiser accessories" forum regarding extended batteries. Take a look there.
You can find some on e-bay also.
I suspect someone will be along pointing you toward the SEARCH function shortly.

Exaxctly. This is what I've been emphasizing all over the time, in several of my articles (please follow the Wiki and/or the General forum here and /or my blog ) - for example at http://wiki.xda-developers.com/inde... revolutionary, comparative, numeric results!

Actually bought mine in-flight duty free. I have seen them on Amazon including the new version with solar charger.

Thanks for your reply, Farsquidge!
I am not due to fly until March !!
I will check out more sites!!

Battery fried?

I've. Been charging my galaxy s over night and it got insanely hot. Now I need it plugged in to run. I'm assuming my its dead?
Thanks, ben.

uhhh pretty much sounds like it to me, just phone samsung and say your battery is discharging from full in under 5 hours and its a faulty battery. They'll ask for your phone serial number and then SHOULD send you a new battery completely free. At least they did for me now i've always got a spare battery in my pocket incase my phone dies.

I left it charging and its fine now. Im not sure what lasting damage has been done though!

If your cheap and in need of some extra power, I suggest ordering some backup batts from Hong Kong (ebay). I don't know what everyone's opinion on these non OEM batteries are here on these forums, but I have 2 in shipping right now and have read of other threads that they do the job. I just know I wont be charging these batteries IN my phone, just in the charger base the kit supplies.
I've also read some people making the valid point that if your willing to throw down the cashola on this phone initially, then u can afford the OEM batteries.... but I'm cheap

I've also bought those 2 batteries off ebay Quite a good deal actually as I needed a new USB cable anyway. I'll keep the OEM one as my new battery for now, unless I notice it is damaged

The bundle I ordered also has the USB and car usb converter. I've had my phone for 2 weeks and already noticed my damn cat has put a few teeth marks in my stock USB cable Now it's Canadian with some black duct tape.

the G7 batteries from HK on ebay work really good
i've been using them for a month, and they run as long as the Original that came with the phone
even though they might be fake, they run and look very authentic to me.

Thanks for the info, those are ones I have comming in

yup! that happened to me back then with my PalmOS phones
and also Windows phones
the problem is the USB connectors
some times if the USB connectors plugs in not aligned properly, it causes a weird charge & short of the battery, which results in the over heat, ultimately killing the battery.

[REVIEW] Samsung Note 2 Stand and Spare Battery Charger (3100mAh Battery Included)

I have bought this item: http://www.amazon.com/Samsung-Battery-Charger-3100mAh-Included/dp/B009M5J9HY/ref=sr_1_3?s=wireless&ie=UTF8&qid=1369030345&sr=1-3&keywords=note+2+charger
I am really disappointed with this. First, I thought the unit was defective, since I was completely unable to charge either my original battery or the one that came with the charger (battery EB595675LU, with Chinese writings added to the language list). I tried different cables and wall sockets and got nothing. The unit does have one LED light, but it never came on. Eventually, I noticed that it would actually work if I shoved the USB cable in really tight. I also learned that a 0.000001-inch move would disconnect the power, even if the cable was still physically connected to the charger. Keep in mind that this happened straight out of the box on the day it arrived. It was brand new.
After discovering that the charger could not be moved at all or it would not charge the battery, I was able to charge the battery that came with it (EB595675LU). It charged OK, but I felt it had less power than the original battery. It drained much faster than the original battery, even when I was home with Wifi on instead of LTE. I think that happened for one of two reasons: (1) the charger didn't completely charge the battery, or (2) the battery is indeed crappy/fake/less powerful than the original one.
At this point, I'm unhappy with the quality of the product. It's brand new and I already have to deal with the problem of the cable moving and disconnecting the power. If this charger is really from Samsung, this quality is unacceptable. That's terrible. But wait! There's more! I used the second battery until it died and tried to charge it in my phone. No problems there, but the charger completely died. Yes, died as in completely dead. And I've charged one single battery on this thing! Now nothing was working. Original battery, second battery, nothing. It just gave out on me. I looked at the battery contacts and noticed that one of them was not aligned with the other two. I touched the crooked one a little bit and it started working again, but still gave me the USB cable problem (disconnecting power). The crooked contact is still crooked as I didn't want to force it and risk breaking the damn thing.
I wanted to buy this charger and the extra battery because I'll be going on a trip soon and didn't want the extra weight and thickness of an extended battery. I chose to get a second standard battery and a separate charger, so I could just swap batteries on the go if needed. I really hope the unit I got is defective. I can't believe Samsung would put out such a crappy product and expect it to sell. I definitely don't want to be in the middle of nowhere on my trip and find out the stupid charger gave out on me at night and my second battery didn't charge. And what's worse is that just about every separate charger I found on eBay/Amazon has terrible reviews due to quality issues.
My goal is to have a reliable/trustworthy separate charger and a second standard battery. I'll be able to maintain my phone's thin profile, have enough power to take lots of pictures, and have no charge downtime other than overnight. Power banks and extended batteries wouldn't work for me in this case. I hope this review has been helpful.

I have the official Samsung battery & charger stand. Bought mine directly from Samsung using a 50% off code from registering the phone. Works as it should and can be moved around. Only cost 20 bucks, too(50% off)
Sounds like yours might be a knock off. Send it back & get a refund. If you need a 50% off code, pm me.

Replaced my Tab S battery/USB port but still not starting/charging

Hey everyone,
I recently replaced the battery and USB port in my Tab S 10.5 because it wasn't charging properly and the battery eventually died on me. The battery was sitting around for about 1.5 years before I got around to installing it and I believe it was second hand. After replacing the battery/USB port I realised it still wasn't charging so I tested the battery voltage and realised it's 2.81v when it should be 4.2v on both cells when charged (it's a 3.8v battery).
Does anyone know what is the likely problem? I don't know if 2.8 volts is too low or if that's just normal discharge voltage. I need to know if it's worth me buying a new battery or not because obviously I don't want to spend the money on another battery if the problem is something else. Is there any way of troubleshooting whether the battery is the problem or not? What other problems could cause a device to just not start entirely? I know the charging port could be another issue but that's why I replaced it, the replacement was second hand though (despite being advertised as new). Nothing bad has happened to the tablet, I've never dropped it or got it wet for example.
Sorry if this is the wrong place to discuss hardware like batteries but I couldn't find any other place to discuss something like this.
Thanks for any help,

Hello,
Please check the soldering join of the battery socket on the PCB. You may need to use a magnifier or similar tools to get a good look. The solder joins seem to be pretty weak and could be damaged when you replaced the battery. Socket pins on the plastic plug came with those Chinese replacement battery has high insertion force. They make good contact with the pin on the plastic PCB receptacle but could exert excessive force on the PCB join during engaging or removal. It is feasible to repair it if you have suitable soldering tip (chisel type is better) and good eyes. Space is limited due to the RF shielding cage right besides the join. Try going in from the top near vertical way. If available, try working with a microscope.
I went through more or less the same thing you had. First replacing the battery, and port, But performance was strange. Sometimes it charges well to 100% But once in a while it stops in the middle. When the capacity went below 60%, tablet could reset under heavy use. Sometimes it drops from 40% to 15% in less than 15 minutes. It got worse and worse. After installing 3C Battery Manager, I found out there was sudden and severe voltage drop and temperature spike when resetting happens. At the beginning I suspected battery issues as we all know getting those replacement battery is like a gamble. I got another battery from a different vendor and similar thing happened. After fixing the soldering joins, it works really well now and I can enjoy a few days on light use without charging.
Also, some of those replacement batteries are picky on charger. Most likely due to the "innovative" cost-cutting protection circuit design. Some fast charger use a very low charging current and takes very long time to get to 100%.
Good luck !

If it's a multilayered PCB be very careful soldering it. You need to know how to solder well. Excessive/prolonged heating and poor desoldering technique can destroy them.
Replace the battery and go from there. It may have auto shutdown from low cell voltage, if so it's not worth mucking with.
If that doesn't get it's probably a mobo failure of some type.

Hey guys thanks for your replies. Sorry that I forgot about this after I didn't get any replies or I would of updated it. I did manage to get it sorted, the problem was the charger I was using, it wasn't providing enough current so the battery refused to charge at all. It would only charge when plugged into the mains on a decent adapter.
