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 ?

    It is not safe, it will explode, leak poisonous gases, kill everyone and all puppies and kittens, smack Earth out of its orbit into the Sun, and so forth.

    Having said that, some 6 months ago I noticed my 2 year old Samsung A71 had a slightly fat back, so after a few months (it was steady, not growing), I took it to a repair shack to have the battery replaced. The guy asked me if the battery was still holding normal charge, and I said yes, a whole day of usage.

    He asked me if I wanted to just “deflate” it. Well, yes.

    So he did what you said, and the universe is still unharmed.

    But in my case it was just gas trapped in the battery envelope; probably it overheated once while charging, but there was little or no damage to the battery itself. If even after passing gas yours is still swolen, it may mean your electrodes are deformed, which is probably more risky than my case.

    I’m not in any way recommending you to keep using it. It worked for me, but I’m a very lucky person.

      You should seriously never go back to that person again. That’s absurdly irresponsible, and even if he somehow knew for certain that it wasn’t about to explode (he did not), the amount of liability he’d assume giving it back to a customer like that is way too high for any reputable shop to consider doing so.

      There is not a chance this happened in the US, because the moment he noticed the battery was in an unsafe condition, he was expected legally to perform due diligence and dispose of it safely. The fact that he not only returned it to you, he made it even more unsafe, you would be able to sue him had it blown up later.

      If you still have that phone, give it to a (DIFFERENT) phone repair store to throw away immediately, or another battery recycling center. It’s not only a danger to you, but to those around you. Potential for fires, toxic smoke, and injury.
