Black & Decker VP110 VersaPak Gold 3.6-Volt 2 Amp Hour NiMH ...
If you've got VersaPak tools, granted, you don't have a choice of batteries, but even if you did, we'd still recommend these Gold batteries for great power, reliability and long battery life. But the Gold version lasts half again as long as the standard batteries, meaning longer use and longer battery life in the long run. 6-volt VersaPak Gold Battery. The VersaPak line of tools all use this battery, and their main advantage is freedom from "memory," which keeps you from getting a full recharge. We know they get a lot of use, so we're glad to see Black & Decker offering single replacement Gold batteries to keep everything running smoothly.
