Well what about XRP 12-18 Volt DeWalt batteries & chargers? They advertise they have a "tune up" mode on their charger where they recommend something like after every 10 charges of the battery, you let it sit on the charger for 8 hours so it can tune up the battery supposedly. How does this work with what has been said?
I can't speak for the technology that DeWalt may use. I do have a smart charger for other types of NiCads and NiMh batteries. For the NiCads, that particular charging system has a "conditioning" mode which basically drains the batteries and monitors their condition with regard to heat, resistance, battery voltage etc. At the proper point they are then charged, agian with the battery being monitored. Recommendation for "conditioning" is for every 15 to 20 charges, I believe.
After working more with one of my friends he told me that if his dewalt is ever unpluged while charging it will drain the battery again and then recharge it. and after that happens it really starts to kill your battery.
My ridgid batteries are charged once and if unpluged it will start over by checking the battery. If it is fully charged the red light will stop and the green will be on without blinking. Telling me the battery is already fully charged.

Polar Sparky, I think what your friend said might not hold water. Reason I say is because I have had the charger plug pulled on my 14.4 drill's charger/battery numerous times (it drives me nuts, I try to avoid having it happen but some dolt comes along on the construction site..I've sure you've heard the story). Usually what happens is when I plug it back in it blinks for about 2-4 minutes and then the light goes solid again indicating it is charged. It is a 1 hour charger, so if it drained the battery again and then had to re-charge it after it was unplugged then you'd think it would take more than 2-4 minutes for the battery light to go solid again indicating it is charged.
I just went by what my coworker said. I have a dewalt as well and mine will always charge it for an hour. My ridgid will check the battery and then charge it.
It could be user error or product defect.
Was your charger and battery made in Europe? [img]tongue.gif[/img] [img]tongue.gif[/img] just kidding
at my jobsite it is too cold to charge your batteries and so the red light always comes on, even if the battery is totally dead.
