Hello!

You need one which lets you adjust voltage and current. Set the current at 1/10 of the battery capacity for NiCd batteries and anything between 1/10 and 1/3 for NiMH. This also benefits the longevity of the batteries compared to the unregulated charging of the original chargers. Regards Max |
