The new VR420 14.4V lithium-ion batteries provide high energy density and include a SMBus (System Management Bus), SBS (Smart Battery System) compliant impedance tracking fuel gauge that allows the battery to communicate pertinent battery data between itself, a smart host and a smart charger.

When configured in a product, the host equipment is able to request dynamic information from the battery such as runtime to empty, cycle count and discharge current as well as static information such as serial number, manufacturer name and part number. Additionally, a five-bar LED display on the battery case allows the user to easily determine the state of charge in simple 20 percent increments.

The VR420 includes its own active and passive protection devices which prevent it from being over-charged, over-discharged or overloaded. Holding safety certification to IEC62133 and UL2054, the VR420 is easily designed into new devices with minimal time and cost.
