Hey Ron, I have several cordless tools as well, Dewalt and Milwaukee, sounds like you have Ridgid. I can't directly answer your question, but can tell you some other stuff;
1) Don't let your batteries freeze, or leave them in a hot vehicle
2) I know a guy with several crews and they invested heavy into Ridgid because of the lifetime warranty. They now regret this because even though replacement is FREE, the batteries don't last. Sorry.
He is no fool who gives what he cannot keep to gain what he cannot lose
If you cannot stand behind our troops, (and I understand, no judgement here), then please stand in front of them, remember, they're willing to stand in front of you!
