Sir, I accidentally put a hole in battery while removing. Will this create a problem/explosion..

Geoff Wacker - May 12, 2016

Hey Apawilo. A punctured battery has potential to be very dangerous (Fire, harmful chemicals, etc), so please make sure to dispose of it at the nearest e-waste recycling site.
