Hi,
I used to have a 1800mAh battery for my JAMin (an aftermarket Ebay one). I made the mistake of sending my device for repair (screen replacement) with that battery and got a 1200mAh battery back (well - I should have seen that one coming). To cut a long story short - ordered another one. This one looked OK so I put it in my JAMin and it was OK for one day. I then put it to charging (second charging) and suddenly the device had a soft reset and would not come out of splash screen. I picked it up and the battery cover felt hot. I opened it and the battery was very hot on one side. Took it out and put it in a safe place but it would not cool down. I was concerned it will catch fire so I opened it and disconnected one wire going from the battery to the PCB inside. It then cooled off (the PCB was hot - not the LiPo cell). I connected the wire again and it seemed to be OK now but I was not willing to risk it again. I opened one of the 1200mAh batteries I had, thinking about switching just the control PCB. The original battery had a better looking PCB (more professional looking) so I connected it instead of the original PCB. I put the battery back in but now it shows 0 capacity all the time, will not go out of splash screen without a charger connected (WinCE low battery protection??). I know the control PCB has a device with EEPROM and RAM inside so my thoughts are that the RAM must have had a reset when switching cells and needs some refreshing. Any one knows how to do that????
Thanks,
Nir
