Vita with dead battery
After a few years I just dug up my PS Vita PCH-1003 and its charger, and after a few hours it does seemingly charge fully, however it only lasts about 20 seconds even connected to power, and I can't even set the time before it dies. My theory is that the battery is chemically dead, but I read somewhere that this might be a calibration issue and could be solved by unplugging and replugging the battery? I don't really have any hope for this, I've recharged it three times and the same thing happened all three. I'm hesitant to recharge it again because I don't want to agitate the Li-Ion battery and have to deal with a dead, swollen battery. I'm open to a battery replacement, given it seems very simple per the ifixit page, are the ifixit batteries good?
