The charger we received in the kit has no way of letting you know that the battery has been charged. I'm not sure it even checks -- we left a prior year's backup battery plugged into it over the weekend, and it was very hot when we got back to it. That battery seems not to hold a charge very well any more...

I am invoking justified paranoia and directing that our team not use this year's backup battery charger unless we find reliable documentation that it indeed will not overcharge the batteries.
