Can your battery explode if its bieng supplied 1.2 volts more then required?

I recently heard my friends battery exploded he was using the same chrging setup as me exept he was using a 1 volt battery i am using a 3.8 volt battery both our chargers supply 5 volts so i was wondering if my battery can be damaged or can it explode if i keep using the 5 volt charger on my 3.8 volt battery (the battery is a lenovo l13d1p32)

Yes, you're using an inappropriate charger on a Li-on batt.

Its meant to be charged with a charger designed for lipo/li-on batts max cutoff voltage of 4.2v and you're pumping it with 5V.

Its only a matter of when it will blow and set its surroundings alight.

Learn about the charge requirements for a particular batt before messing with them or risk injury.

Thank you im currently looking for chargers that are compatible also what i dont understand is that the charger came with a phone (just5 freedom) and that phones battery from what i understand has a max of 3.83 volts so thats why i thought it was just fine but now i know thank you

The phone had a charge controller on board. this allows them to be charged from a USB source.

You need to look at chargers for RC batteries.

Ummm im using a lenvo tab3 8 when i was saying lenovo l13d1p32 i was just refering to my tablets battery witch is the l13d1p32 also maybe the charger just5 tcau10e (ive tried to google it you wont find anything about the actual charger) and maybe the 5 volts are its max and maybe somehow it can check how many volts your battery needs becouse all the chargers ive seen either dont say how many volts or they say 5 volts or 5 volts max idk now im just using my tv's usb port to charge my tablet now

What's a 1V battery? 1.2V? 1.5V? 1.6V?

1.2 and the batt that he was charging didnt have any skrt of pretection againt overcharge and he was charging it seprettly so he was using charger that can supply 5 volts and so the charger just was pumping the battery with 5 volts when it only needed 1.2 luckaly he was charging it in his kitchen so the fire estingwisher was right next to him

Just buy a $2 charger online. You might not burn up your house, but fire extinguishers don't stop explosions and dangerous chemicals!

every charger i found at my local store and internet store wasnt 3.8 volts all of them were 5 volts what im guessing is that they dont actualy supply 5 volts they supply the amount of volts the device requires and that the 5 volts thing is their maximum voltage they can supply say a device requires 6 volts but the charger can only supply up to 5 volts but a device that requires 4 volts it will supply it with 4 volts but thats speculation also my friend had to move out his ensurence company coverd the cost of getting everything back

3.8V is nominal voltage of newer lipo batteries (you can Google for more detail about newer lipo nor what is nominal voltage). Your battery has 4.35 V or 4.20 V when fully charged. So, you have to push bigger than that number into battery to charge it. And 5 V is OK for that job.

Lipo batteries are sensitive about few conditions. Overcharging is one of them. You need a charger for Lipo. If your battery nominal voltage is 3.80 or 3.85 look for a charger for H-Lipo. I'm strongly suggesting a good quality charger for lithium based batteries.

Quick hint: on overcharge situation Li-Ion batteries could explode, Lipo batteries could start short timed strong fire (No explosion on Lipos, which is so many people thinks both are explodes).

In other hand, from your question title "1.2 V" nominal is NiMH or NiCd batteries which are more safer than lithium based batteries about overcharging. However, overcharging will decrease battery life a lot. In both case; suggesting a good quality charger based on your battery type.

I think that's right, where they're an "amp power supply", something like that.

Also keep in mind of load/no load voltage.
