The 4-Hour Rapid Charger for AA and AAA NiMH and NiCd Rechargeable Batteries from Watson charges 2 or 4 AA or AAA batteries (not included). It is compatible with both NiMH and NiCd batteries. Charging time varies from 100-280 min, depending upon battery quantity, size, and capacity.
The charger's intelligent Negative Delta-V microprocessor doles out the full charge to each battery, while Zero Slope Detection prevents overcharging. The Safety Guard Timer automatically shuts off after 6 hr in cases where batteries are taking far longer than normal to charge, in order to prevent damage from excessive current.
The charger has two charging level indicator lights to keep you apprised of battery status. Switching 100-240VAC input power enables use all over the world. The charger's compact outlet prongs can fold in, making the unit more compact for storage.
Will charge either 2 or 4 AA or AAA batteries (sold separately)
Works with batteries that have Nickel-Metal Hydride (NiMH) or Nickel-Cadmium (NiCd) chemistry
Charging time varies based upon battery quantity, size, and capacity. Charging 2 AAA batteries will take about 100 min, while 4 AAA's will require about 200 min. Charging time for 2 AA batteries with a capacity of about 1800mAh will be roughly 110 min, while 4 AA batteries at that capacity will require about 220 min. For higher-capacity AA's in the 2400-2500mAh range, 2 batteries will charge in approximately 140 min, and 4 batteries will take about 280 min
An intelligent Negative Delta-V microprocessor ensures that each battery is charged to its full capacity, while the Zero Slope Detection feature prevents overcharging
