MHX7 NiHM Battery Charger

NDX40 NiCd Battery Charger

 

The NDX40 is a precision constant current quick charger that uses negative-delta-V detection to terminate the charge. When charging is complete, the current is pulsed to maintain the battery with a full charge and to avoid cell degradation due to dendritic (crystalline) growths. The precision voltage sensing in the negative-delta-V circuit is appropriate for both NiCd and NiMH batteries.

Optional Temperature Sensing
When charging at fast rates, many battery manufacturers recommend using a temperature sensor to stop the charge when the battery gets too hot. Also, they do not recommend charging batteries at cold temperatures. A 4-wire output cable for connecting to a temperature sensor inside the battery pack or a remote temperature sensor cable for attaching to the battery pack exterior are available as options. These will prevent or pause charging when the battery is either too hot or too cold to safely charge. The charge will start or resume when the battery temperature returns to a safe range.

 

Warranty
