The MC4S is a compact charger for up to four batteries, which can be charged independently of each other. It does not matter whether the batteries are of the same type. The device detects the battery type and charges them in the optimal way. It actively protects the batteries from overvoltage, overcharging, and short circuits.

In the rejuvenation mode, the charger can "revive" batteries that have been unused for too long and can no longer be recognized or charged by most devices, and then charge them. However, caution is advised with lithium-ion batteries, as deeply discharged batteries below 2.4V can lead to capacity loss, and discharges below 1.5V can pose a potential danger. Such batteries should be disposed of at a specialized store for safety. Batteries should not be placed in regular battery disposal!

The charger features a three-stage charging cycle that is particularly gentle on the batteries.
