Important note: Due to the erratic charge behavior of NiMH and NiCad batteries when first placed on charge there is a delay of up to 15 minutes before an accurate charge termination can be read. In worst case a battery can be taken off the charger and reattached, and charged for 15 minutes before the "charged" light comes on again. In addition, new packs should be charged and discharged several times before they "settle in" to a predictable charging condition.

Advantages:

OEM Battery Chargers Inexpensive desk top Nicad and NiMH Battery Charger with peak charge control circuit, universal AC input version.

OEM Power SuppliesSingle LED changes color to indicate state of charge.
