Dunamis USB AA / AAA battery charger, powered by 5v USB socket and suitable only for charging 1.2v AA or AAA Ni-MH or Ni-CD batteries. Includes Dunamis 4 Pack 1.2V 900mAh Ni-MH rechargeable AAA batteries. Ni-MH batteries are the safe and environmentally friendly option for rechargeable batteries as they have little or no memory effect and will last for many more charge and discharge cycles compared to older Ni-CD types. Life expectancy of these Ni-MH batteries can be as much as 1000 recharge cycles! AAA Size, 900mAh rating meaning these batteries are capable of being used in medium to high drain devices including Bluetooth headsets, XBOX controllers, digital cameras, electronic toys, torches, audio & mp3 devices. Always try and install a Ni-MH rechargeable battery close to or higher than the rating of the one that is already in the device, for best performance! Ni-MH batteries have low self discharge meaning they will retain a charge even when not in use for a period of time. Dunamis batteries are PRE-CHARGED so can be used straight away. However it is advised to charge fully before use if possible, as they may not be charged to the complete capacity of the battery for shipping safety purpose. Ni-MH batteries will reach top performance after 3-5 times of a full charge cycle.
