Skil SelectSystem™ is designed for you to have total freedom with your cordless power tool selection. With a choice of fully compatible Lithium-ion or NiCd batteries and chargers, together with a large range of bare tools in the Skil SelectSystem™ range, the time has passed when you need different batteries and chargers for all your tools.  For even more great value, take a look at the Skil 18v Cordless Combo Kit 2888-40 or the Skil 18v Cordless Drill/Driver pack 2888-20, which both come complete with two NiCd batteries and a charger, then add more bare tools or batteries as required.
