Minimize down-time with this fast and efficient charger from DEWALT. The DC9310 charges every DEWALT 7.2-volt to 18-volt NiCd, NiMH, or Li-Ion battery (with the exception of UniVolt batteries) in about one hour. A helpful LED indicator tells you the charging status (charged, charging, power line problem, replace pack, and battery too hot or too cold), as a three-stage charging system does its work.
