Li-ion battery overcharge

So one day I left a Voyo A1 mini tablet charging for a little too long, I thought, oh well – I will replace the battery at a later time and just leave it in a box for now.

Leaving an over charged Li-ion battery in a box for 7 months isn’t the best things to do ….


Sorting some things out some time later I found the unit and wondered why the box wouldn’t shut completely, a peak in side and I see the below! luckily the box wasn’t kept next to a heat source as i guess things could of been worse.
