Power up your photo equipment, flashlights, gaming devices, and other electronics via the Watson MX 4-Hour Rapid Charger with 4 MX AA NiMH Batteries. The 1.2V, 2550mAh nickel-metal hydride cells are pre-charged, rechargeable up to 500 times, and capable of retaining 85% of their capacity after 1 year in storage. The Rapid unit will charge 4 of them in about 310 minutes, or 2 in about 160 minutes. It's also compatible with optional AA NiCd batteries, or AAA NiMH or NiCd cells.
The charger's integrated micro-controller ensures that each battery is charged to its full capacity, and an automatic cut-off feature prevents overcharging. Should the controller and automatic cut-off functions both fail, the safety guard timer will kick in to ensure that power is still shut off after 6 hours. Additionally, the charger features protection against short circuits and reverse polarity. Two charging channels are individually monitored, and two LED indicators display battery status. In order to enable use all over the world, the charger runs on 100-240 VAC power. As a bonus, its compact outlet prongs can fold inwards, making the unit more compact for storage and travel.
