AA batteries get hot while using

[mohitdaksh]

Sorry I could not find any other place for this question. I have a canon powershot is130x, it requires AA batteries. The problem is that the batteries get hot even after half an hour of usage. Is this thing normal or is there anything wrong??

As current is drawn from the batteries they will naturally heat up, basic principal of electricity. Flashes can draw a lot of power when cycling, and charging. So ya that's a normal thing, no worries.... if they explode(they won't) do to heat then you have a very defective battery, and it will most likely never make it into your flash.

What type of batteries, and how hot? Just warm or uncomfortable to touch? As Azaki says, some amount of heating is normal, but getting excessively hot could indicate a fault either in the camera or the batteries.

I have uniross NiMH rechargable batteries. They get very hot.. Hotter than when they are getting charged.

It is most likely because you are using NiMH rechargeable batteries. Your normal (Alkaline) AA battery is 1.50 volts. Most NiMH batteries are only 1.25 volts. The camera needs a certain amount of power to run properly. Since your batteries have a lower voltage, the camera is drawing from them even harder than a standard battery, thus creating more than normal heat. If you want the heat issue to go away, use Li-FeS2 (1.50 volt) or NiZn (1.65 volt) rechargeable batteries.

This perfectly normal. A couple of times during portrait sessions, I have actuly thrown the batters that where just in my flashes they where so hot.

OK, if the NiMH batteries are getting too hot to hold, you are overrunning them. This is bad for the batteries, causing reduced capacity, and may cause eventual problems with charging such as outgassing and even thermal runaway. The heating is likely to worsen over time, maybe getting hot enough to damage the equipment they are installed in. It will certainly reduce the number of charge/discharge cycles you will get out of them. You need to get new batteries that are appropriately rated for the current you are drawing.
