[Barnes & Noble Nook Tablet] Darth Newton:
I realize this is a old post but I thought I would chime in on it. I have done a lot of research lately as I have a battery issue. Well it is a problem with phantom touches when the battery gets to 23% or so. From all I have read this is a battery issue. At first I was thinking it needed to be calibrated. However after digging though all the information, most battery calibration methods just delete the battery stats. This apparently is only data since the last time the device was charged, and not long term information that affects calibration (confirmed by a Google engineer). I did read about one other file to delete in \rom max#### if I remember correctly, and that might do it. I may try that soon.

The only other method I saw was to charge it full, run it down till it shuts down, charge it till full, turn it on and let it sit ON for 30 minutes (set screen shut down to 30 minutes), then plug it in to charge full. With some Android devices this can recalibrate the battery (which makes sense), but not sure if it will work on a NT or not. I am going to try it though.

But back to the battery, I did like the look of it and the video they did. I may purchase one from them if all of the above methods don't work. Someone else got a 3rd party battery from another company and said it worked well http://xdaforums.com/nook-tablet/general/changed-battery-nook-tablet-t2829771 it is the same capacity which IS less than a original NT battery (3200 vs original NT at 4000) so you won't get the same runtime that you would with a brand new NT. That said all LI-ion batteries degrade with age, so even if you happened to find a new unopened device, the battery would not quite be the same as when it was released. Also while you can get batteries from say Ebay, you do not know how many cycles or life is left in them. Could be a few days, a few months or years. Even if they say 80% of the capacity is left in them, that is approximately what you will get with one of the new batteries anyway.

The one company is cheaper than the other (20 from batteryship.com vs $40 from newPower99) and they are the same capacity so I am not sure which one you would want to go with. As far as presentation goes, Power99 wins with their nice video on you tube and the look of the battery itself. Both seem to include the two tools necessary to do the battery replacement. So again up to you which way you want to go. Both have 1 year warranty. One thing about newpower99 they will install it for you for $60 http://www.newpower99.com/Battery_Replacement_Service_for_Nook_Tablet_p/nook-tablet-pbr.htm I can't vouch how well they do but if someone is really worried about doing it, then I would say let them do it instead.

Personally though I would just do it myself. But I did just find this on the newpower site "•Opening an electronic device and replacing the battery does entail risks to the functionality of the unit. NewPower99.com does not guarantee the overall functionality of your unit after battery replacement service. You acknowledge these risks and understand that NewPower99.com's maximum liability is limited to the cost of the battery replacement service." Which doesn't instill confidence in sending it to them lol.
