[SOLVED] Does heavy duty relates to higher risk of battery exploding?

We've seen battery exploding news everywhere.
Does heavy duty relates to higher risk of battery exploding?
For e.g., could my macbook pro battery explode if I'm running several heavy duty intense tasks?

Overall, not something to worry about per se.

Heavy use is probably the least likely issue involved.

Laptops and especially those from high end brands have sophisticated charging and battery monitoring safety features. The only time a fire would happen is if the battery is damaged/faulty or the charger and safety features fail. In either case there is nothing you as the user can do. However the chance of this happening is very small. I use the same type of lithium cells for model aircraft and they get far more abuse in this scenario, I can discharge a battery in some models in less than 5 mins and there are no safety controls built in and I’ve never had a fire but I know they occasionally do happen.

I see what you mean. Thanks!



I guess heavy duty will make laptop hot, and high temperature may have a bigger chance of triggering a battery explosion in average?

I guess I changed my question to:

For a Faulty battery, will heavy load which is higher temperature has relation to a higher risk of explosion of such battery?

A faulty battery can catch fire when not connected to anything. It’s rare but can happen. I’ve seen reports of damaged batteries catching fire days later. Heavy load from a laptop is still very low load compared to what these cells can deliver. If laptop batteries were being pushed hard you would not get anywhere near the number of cycles out of them.

Thanks, I guess the question is answered as it's not related between heavy load and faulty battery risk of explosion.

I wonder, how do we know if the laptop's battery is faulty? I used to use 2 macbook pro, both swell without give me any notice.

A laptop should stop you being able to charge a battery that is too far out of spec. One cause of battery swelling is keep the battery at a very high charge state, 90% or above. Did you have the laptop plugged in and charged to 100% most of the time? My current Dell and other laptops I’ve owned have had applications that allow you to cap the maximum charge level for users where the laptop is mostly plugged in.

yes my bad for keeping them charged all the time. But , is there a way for us to know or get noticed that the battery is faulty?

Not that I have seen. I have seen laptops refusing to charge, not even trying to charge but no other warning.
