There is no easier way to charge your Lithium SLB Series battery than with the SLB-0737 KIT universal battery charger & battery set. It's as simple as plugging the unit in to the wall anywhere in the world and inserting a battery. The SLB-0737 KIT features charging times as fast as 90 minutes (with the included SLB-0737 battery pack), yet is small enough to take anywhere.
