The charger operates in a constant current mode until the battery voltage reaches the desired level, then switches to a constant voltage mode to finish charging. The charger has a built-in fan to keep the components cool, and a soft-start circuit to prevent current in-rush. The charger also has a delay-start circuit to prevent arcing of contacts when the AC power plug is inserted into the outlet. The charger has a temperature compensation feature that adjusts the float voltage according to the ambient temperature, as shown in Figure 1. This feature helps to optimize the battery performance and lifespan.


The charger has a power rating of 20W, and can deliver a maximum charge current of 3A. The current drain for balancing is 200mA. The charger is filtered to prevent radio and TV interference, and has multiple safety and protective features to prevent injury or damage. The charger has a heavy-gauge corrosion-resistant aluminum case that measures 6.5 x 3.5 x 2 inches, and weighs about 1.5 pounds.
