Is it safe to use a swollen battery(less swollen)

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 ????

EDIT ↓

EDIT - I got rid of the swollen battery and now the mission was to get the smartphone working witty a new battery, so i checked online for new battery for my samsung j3 prime and i found nothing !!! So i decided to take matters in my own hands and searched for some old phone in my dad's stuff (and i found some really old samsung phone in really good condition) I removed their batteries and checked if they will work with the current j3 prime, the problem was that the battery that i found had 3 golden pins and the phone required a battery with 4 golden pins (idk what to call those pins specifically) So i just stuck the 3 pin battery in the phone powered it on and voila it works and after that i made the battery stick to the back of the phone by folding a piece of paper on the empty space(the traditional way), after that i attached the back of the phone and now it is working, the only catch is that the battery backup is quite low but i can live with that. Here the pic of how i made it fix

So i wanted to ask that is it ok to use the new battery? Considering that it has one less golden pin ?
