How to reuse old tablet battery for a usb PowerPack Answered

Hi, i have two 3600mah batteries from an old chinesse tablet, I would like to use as an portable battery pack for charge a cellphone.
i searched for similar instructable but i have no find anything, what is the next step


Well if you have the charge circuit for the tablet so you can recharge the battery as needed then it can easily be made into a backup battery for your phone. Just buy this Minty Boost kit and use that battery instead of a pair of AA batteries and your all set.
