[Shop-talk] Battery Clarification

Moose,

I think you are doing pretty much what you should do with the DeWalt 
batteries. They don't like deep discharge. I usually remove my batteries 
from the charger after about 24 hrs. This gives them time to charge 
fully, and run through the "conditioning" cycle that my charger says it 
does. I've absent mindedly left batteries in the charger longer, with 
the charger not plugged in and the batteries are totally discharged in a 
couple of days. I try to not leave them on charge longer than 24 hours 
though. I have been getting 4 or 5 years out of my batteries.

Peace,
Pat
