I have gotten myself a new battery but the battery is only 52% and the LED light is not Red meaning it has finished charging. How do I calibrate my new battery?
Update:
As I am charging, I noticed that the percentage keeps going down. From 64% to 53% now. What's wrong?

just because your led is not red doesn't mean it's finished charging. it's finished charging when the led is green. (well, it's green when it gets to 90% charged, but you get my point)
The led is red and from the notification, it shows as charging, but my battery life is depleting, asking me now to connect to charger. You get what I mean?

To recalibrate I do:
1.Wipe batt stats
2.Let new batt die out fully
3.Recharge till 100% by looking @ lock screen or spare parts
*I've only used wipe batt when using diff rom.
As in the previous battery works fine, I can charge with it. But this new battery doesnt seem to charge although it says in the notification that it is charging...

Today is a week since I've got my Nook and it's battery started to bother me.
When I fully charge my Nook and indicator shows 100% I unplug it and in a few seconds charge level drops to 99%, after this battery discharges in normal pace, Is it some kind of software glitch(I use Nookie Froyo 0.68), or in just a week Nook's battery started to loose capacity?
There was an issue whith a battery before. I had to connect my Nook to MacBookPro using generic microUSB to transfer some files and in about 10 seconds battery charge indicator jumped to 100%, could it be a reason for current battery behavior?
Is there some kind of fix available?
Thanks in advance.
Try charging til it turns green then edit about an hour. Boot into CWR and clear battery stats. Then unplug and see what happens.

You can try that, but Correct me if I'm wrong but as soon as you unplug your nook and run from battery at the very Nano Second the Battery is no longer at 100% so the Indicator would be correct, seeing as it only does Whole %.
But really Ehudbenjamin's Answer is better, Its most likely just the stats the OS uses to track the usage that is mess up. or Maybe Android, uses a very Strict Battery usage policy when displaying %
Doesn't sound like something to be super worried over tho.

Li-Ion batteries have a governor to prevent overcharging. When the battery reaches 100%, it stops charging; even if it remains plugged in. After a certain amount of discharge, the governor allows the battery to charge back to 100% again.
Depending on when you are when you unplug your device, you may see it remain at 100% for a longer or shorter period of time.
Thanks for the answers, but it actually didn't help. I just charged my nook from 10% to 100% and in a minute after I unplugged my charger, indicator showed 99%. As I noticed, charge percent is calculated based on battery voltage and it drops nearly immediately, when I unplug a charger.
The battery of my Nook Color (CM7 - build 128) does not charge over 50%.
The battery completely drained out (I probably left it on standby for 1 week) and now when I recharge it the charge level always stops exactly at 50% (shown on Spare Parts). I also noticed that when the charge level reaches 50%, the color of the 'n' symbol on the USB cable becomes green (maybe it thinks that 50% is now the maximum charge level?)
Can someone help?
Thanks!
If you have cwm installed, go to advanced option and reset battery stats. Then reboot and charge your nook. Looks like the complete drain might have screwed up the reporting on charge. I would recommend charging the nook while it is turned off and see if that fixes the problem.

I tried to charge the nook when it is off, but it automatically powers itself on anytime I connect the USB cable. I do not remember it behaving like this before.

Good. So i see you're using build 128, you might try updating that. I don't recall when some of the battery calibration problems were fixed.
One thing to be clear on is even if your NC is saying it's 50%, if the charger stops, the battery is full. The charging is independent of Android, so it's not like it's overcharging etc. Most likely it's a calibration issue.
Get up to date on CM7 and use the NC until it powers off on its own then plug it in and don't touch it. It will turn on by itself. Leave it alone until it's done charging, see where it is then.
I am not new to the phone and I have done battery calibrations many times. I used MIUI for a long time, then went to Pinnacle 1.1. After a few weeks one night after fully charging, I unplugged the charger and it dropped to 70% instantly. I could then plug the charger back in and it will not move from 70% for a while, then it will register 'fully charged'. Removal of the charger again will make it drop to 70%. Turning off the device and charging will show the green battery about 2/3 full, but not registering full. I then went back to MIUI thinking it was a rom flaw, but this problem has persisted. I am right now charging on stock JF6 with the same results. If this is indicative of a defective battery, has anyone seen this before? The battery is 14 months old.
TL;DR - It seems that the battery wont charge past 70% regardless of ROM/Kernel.
I had a similar problem but it was because I wasn't using the charger that comes with the phone switched chargers problem was solved.

I drained the battery last night, and then charged while off fully. The green battery icon went to 100%, and as soon as I turned it on it said 73%.
You might want to check into getting a new battery I got a extended battery for 10$ you can probably find the original sized battery for about the same price if you look around.

Google "bump charging". I had a similar issue when I was on serendipity vii, it would charge to full, but as soon as I unplugged it would drop to 80%. I bump charged, then calibrated. All was well after that.

Tried that. It hangs at about the 2/3 full level on the large green battery icon when the phone is charging off so I really can't do a proper bump charge.
I think I am going to resign to it being a battery past its prime...
New batteries are fairly cheap, plus I've heard that if you even mention faulty battery to at&t they ship you a new one for free...

I find that hard to believe, but it can't hurt to try!
Sounds like you need a battery calibration..
1. discharge completely
2. plug into a USB port on the computer for a slow charge up to 100% (overnight while "off")
3. unplug the device and turn it on
4. if you have a ROM with CWM installed, clear the battery stats at this time.
5. plug it into usb until it's charged to 100% (while on)
6. unplug the device and turn it off
7. plug in into usb again until its charged to 100%(while "off")
8. turn it on and use it as normal
This will allow the device to relearn it's battery charging characteristics. This is the battery calibration.

In stages 2 or 5 it never reaches 100%.
I am going to try a coworkers battery tomorrow at full charge. That should settle it.

You are not leaving it long enough. It will reach 100% once it charges what it believes is 30% more. It must be off and you must clear the Batt stats.
Once it stops charging it marks that as fully charged. Your battery needs calibration.

You are right.
I did a small test with a coworkers battery today.
His battery in his phone - 88%
His battery in my phone - 58%
Leaves a delta of 30% which is exactly why mine stops charging at 70%.
It has gotten to 100% while off charging in the green. I then booted to CWM recovery and wiped battery stats, but it turns on at 70% again. It is almost like it isn't deleting the file.

It's true, go to your nearest AT&T store and tell them about your issue and they'll take your information (name, address etc...) and ship you a brand new OEM (Samsung) battery no questions asked. No idea why they don't just hand you one on the spot, but it only takes a few days to get to you anyways.

did you finish the procedure I mentioned? There is a calibration procedure. It involves turning it on and off several times and plugging it in an unplugging it several times.

I followed the calibration instructions perfectly. I have done it quite often actually. Didn't work. It acts as if CWM isn't actually deleting the file.
Deleted batterystats.bin via a terminal emulator and still no luck.

On the lockscreen you will see a long time "charging", and then "charged" when its fully charged.

Sony somehow turns the led green when it reaches 90%. Kind of the same as what I've read not to stress the battery by charging/discharging it fully as it will decrease battery lifespan.
I suggest to unplug it once you see the led turn green as the difference in battery life is minimal whether it's charged at 100% or 90%.

yes, you're right.
Lithium Ion/Polymer battery life can be extended, if not fully charged. charge until 85%-90% only, can make up to twice life cycle.
And when do you start charging, when the battery hit 15-20% ? ( I normally start charging from 15-20%)
