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 ???
