To avoid thread-jacking the other thread currently going on about lithium batteries, I thought i'd start my own.
I have a couple of lithium batteries from back when China would ship them to the UK that I have used for running my small 12V setups. One is fine, but the other has become slightly swollen after a period of no use. Does anyone have any expertise regarding this? Is it still safe to use, is there a way to reduce the swelling, or should I be looking for somewhere to dispose of it? Edited by Blaize110 - 06 July 2015 at 7:18pm |

You can try charging it at a very low rate, the gasses may recombine and the battery shrink back but you need to be very careful and do it in a safe place.
Li-Ion and Li-Po batteries do not like being stored in a discharged state.

I would get rid of it as fast as possible to be on the safe side. What's £15-£20 for a new battery compared to having your house burnt down?

This guy has a great solution (not):

Thanks for the tips, looks like it's about time to replace this one then.
