Re: Battery Management

[Paul Stenquist]

Generally, high temps are a problem only if they cause the batteries to 
vent, but a cooling fan is a good precaution. If you have a fan from an 
old computer, it will make a perfect charging fan. If you don't have 
one, you can pick one up at Radio Shack. Just position it to blow on 
the batteries while they charge. NIMH batteries won't last three years. 
They're usually goners after about two years.

I get the impression that a lot of what people describe as memory 
problems are really just out and out battery damage due to 
overheating and probably other stuff.

I have an Energizer 30 minute charger. The batteries are HOT when they 
come out - they won't physically burn your fingers, but they are too 
hot to comfortably hold in your hand.

I bought this a couple of years ago to replace an older Rayovac 
charger that took about 8 hours to charge up a set of NMHi batteries. 
Unfortunately the Rayovac was damaged when a battery leaked inside of 
it.

I've been tossing NiHI that are in the 3 year old range - they won't 
take a charge from the energizer charger. It's hard to say how much 
use they get since they have been used in the *ist-D, CoolPix 990, and 
lots of flashes. But could the high temps of the charger be a problem?
