Sorry if asking wrong people but I’ve got a samsung galaxy j3 prime, its a really old phone and i lost its charger a year ago, after that until now I was charging it with a different cheap charger, and one day eventually while using the phone the back cover fells of(it has removable back) and then i realised that the battery became swollen, I immediately took the battery out and kept the phone and battery apart for 2 months, now today I lost patience and grabbed a safety pin and did a little hole on both sides of the battery. Now it fits !!! and is much less swollen then before(yes it is still a little swollen)
So I meant to ask would it be safe to use it like that or is there a risk of the battery going kaboom!!! while i am using the phone or charging it ???
No. It is not safe.
Replace the battery and dispose the old one or dispose of the device properly.
Look it up but there’s probably a Best Buy somewhere nearby that’ll let you dispose of it for free not too far from you.
Never poke a battery again, you’re lucky it didn’t burst into flames and you very well could have exposed yourself to some bad stuff.
