What do you folks do, to help keep your cordless drills charged, between uses? I don't quite use mine often enough, and the two batteries tend to be low when the next time I need it comes around.
I've read before that it's a good practice to recharge at 50%, versus most of us use it till it's dead! I've had phone guys tell me that too, especially with lithium batteries .
But when they sit for a while, between uses? My batteries when left in the charger get rather warm. Which apparently means there is no sensor to shut off when fully charged. So I can't do that. Must I attempt to create a routine where I take out the drill, and re-charge on a regular basis? Which being a mere mortal, I do forget...
I don't seem to have trouble with my batteries staying charged. Even if it's been months since I last used it, the battery stored on the drill is ready to go, seemingly at the same level as I left it, UNLESS I forget to move the direction switch back to Center-Off. I'm guessing there must be leakage through the variable speed control. And the spare battery is always stored fully charged - I don't put the drill and charger away until I see the signal that the current spare battery is charged, and the battery is never stored in the (unplugged/stored) charger, again, to avoid possible leakage through the charging circuit. To be clear, the drill and spare battery change assignments when the drill battery goes dead (and gets put in the charger).
