Hi Robert, a certain amount of heating is fine, and indeed unavoidable unless you reduce the current and so increase charge time to more than about 10 hours. A 15 degree C rise in battery temperature is absolutely normal for these batteries (NiMH) towards the end of the fast charge. Much more than that and I might worry. And I wouldn't have thought that the battery should heat up immediately if it's empty when you plug the charger in - how old is the unit? I'm reading these numbers off the battery manufacturer's data sheet by the way.
I'd also like to point out that if I took the cooling fans off my PC it would probably overheat and die within the hour! It's just something you have to live with in some devices. regards, Andy. ---- Andrew Riden Software Development Engineer HumanWare Ltd. 11 Mary Muller Drive, Christchurch, New Zealand.
