With the Nitecore D4 Charger, charging the batteries you use on a day-to-day basis can be made much easier. This charger is able to fit four compatible cylindrical rechargeable batteries at once, with different charging rates activated by automatic sensors of what type of batteries are inside.

This smart Nitecore D4 Charger can automatically sense which of the four compatible battery types (Li-ion, Ni-MH, Ni-Cd, and LiFePO4) is currently in each slot. With that information, it charges it up to capacity, stopping when the battery is fully charged. A helpful LCD panel on the top gives an indicator of the charging progress of each battery and two side buttons allow you to further optimize the charge by selecting different charging parameters out of the options that are available.
