What can cause a battery to suddenly become very hot in your pocket?

Yeah, it's either was touching something conductive like sweat or metal like a coin or small piece of foil.

maybe you need a new battery

Chemicals... mostly some kinda acid. And some have nickle in it, but I donno if it'll be a solid (metal) or a liquid form. Bust one open and ya'll find out whats really in one.\n\nAnd also that's why they tell ya not to leave patteries in electonics for long periods of time with no use, cause the battery would start to leak the acid and it could fry the system.

Bring it into the shop let them check it out for you.  This will save you monney in the long run if it over heats it can burn up you're hard drive or even go on fire.

Just as a precaution. Although it has been proven that cell phones can not cause vapour to ignite (most instances of vapour ignition occurs when the person has a static charge earth themselves when the touch the metal pumps) its better safe than sorry.

First of all the physical care. Find an protective carry case, keep it from heat & cold & Water.\nIt is a good idea to let the battery run down the first few times and then recharge. I am told this is good for prolonging the life of the battery.

hi \nthis is quite good question\nthe source of supply to our home or any battery we use are constant voltage sources that is they try to keep voltage constant.when we short circuit wires positive and negative it provides a low resistance path(a shorter circuit)\nwhich results in high current because of constant voltage supply this causes heating in the wires and fuse or mcb trips for safety try sort circuiting 1.5 V battery in a minute or two it will heat up

The router I have is always hot- even when it is in a well ventilated space. According to the manufacturer this is normal but- just to be on the safe site- I turn it off when it's not in use. Don't worry about it too much.\n\nHope this Helps!

It gets hot.  Hate to be so simplistic, but that's what will happen.  A wire has almost no resistance and virtually all of the energy in the battery flows from one terminal to the other.  The flow heats up the wire and, well, it gets hot.  The larger the battery, the faster this will happen.

I don't know, but mine do the same. \ngood idea why don't you or I invent the heated\nmouse? I could use the bucks.

the computer has a fan to keep the heat down, right?  So maybe the fan doesn't work?  I can't imagine how the computer was functioning if the touch pad was that hot though. Take it in.

There could be another probablitiy.\n\nThe CMOS battery could be weak and loosing power\n\nTry opening up your CPU and locating a Battery on the motherboard. ( round in shape and shiny silver )\n. If you can replace it.

as stated by Kobe, the chemicals inside the battery cause a "difference in potency" at the end caps of the battery. One cap has a surge of positively charged static, and the other, negatively charged static. This causes that whatever is put close to the battery caps, and is a "good conductor" (not like wood, more like metal), will be driven to let direct current flow through it. This process will last for as long the chemicals inside the battery wouldn't mix all together. The "workload" driving negative surge on one side and positive surge on the other causes chemicals to mix all together. When this comes to happen the battery will stop working.

Its better u plugged ur battery out...!\nEvery battery has LifeTimer..! when u left it plugged in, it will decrease its LifeCycle. \nTo ensure lasting ur battery, from time to time, try to charge it nearly 8hrs without turning on ur LapTop.!\nenjoy it ;)

Are you certain it's not a temperature effect?  Most of the unrechargeable batteries I'm familiar with do have decreased power output at low (like around 40 F or less) temperatures.  I can't think of why a lower ambient pressure would cause the low power.

there could be a fuse in the line that has blew or you cold have a short. you can always run a hot wire straight off the battery to your lights never know your lights may have just blown

My iPAQ does that, are you talking about a Pocket PC or laptop or perhaps a tablet PC?\nIt is trying to figure out how much battery life is left..happens especially when you have a complete battery discharge then recharge it.
