Ni-Cd Battery Question

You mean prolonged storage. Do not worry about between-use storage.

Have fun.

I read in sci.electronics.design that Rewar wrote (in ) about 'Ni-Cd Battery Question', on Sat, 1 Jan 2005:

No, but some manufacturers are skilled and some are merely crafty. (;-)

Whether you store them charged or discharged, after 3 months they will be discharged. I charge mine every 3 months or so. Y MMV.

Running your drill down to zero is the WORST thing you can ever do to a battery... ok, ok, you can run over it with a truck, but you know what I mean...At least one cell will get reversed in the process.

When drilling a hole, if your drill takes a sudden down-step in speed, STOP immediately and recharge the thing. Finishing the hole is BAD. I've bought a dozen drills at garage sales. They ALL had at least one reversed cell. mike

Which is what I do and what the Craftsman manual says to do. What bothers me is the following from the Skil manual:

"If you anticipate long periods (i.e a month or more) of non-use of your tool it is best to run your tool down until it is fully discharged before storing your battery pack." Or " . . . ". if you prefer.

So I will go to "sci.chem.electrochem.battery" as jdoe suggested and in the mean time, to be on the safe side, I will discharge them half way.
