USBCELL MXAA02 AA Rechargable Battery - 2 Cell Pack
USBCELL AA Rechargeable Batteries work just like normal rechargeable batteries--but simply pop off the lid to recharge by any powered USB Port. Ideal for use with wireless mice, keyboards, game controllers, and other household products with no need to carry or find a separate charger. Easily rechargeable on the go, in the office or at home. USBCELLs can be charged hundreds of times saving you money and helping reduce environmental waste. USBCELLs are NiMH 1.2v batteries with 1300mAh capacity.The USBCELL has been designed for real-world ease of use. By opening the cap and plugging into any powered USB port, you can recharge pretty much anywhere there's a USB socket. By making it easier to recharge batteries we can help the environment: easier recharging means more frequent use, which means fewer disposable batteries get made and thrown away.In a powered USB socket, USBCELL should take about 5 hours to charge to over 90% of capacity, sooner if the battery was only partly depleted.  Thanks to the intelligent charging circuitry of USBCELL, it's OK to "top up" or just partially charge USBCELL if you need the power in a hurry; NiMh batteries aren't affected by partial charging or 'memory' problems, unlike Nickel Cadmium (NiCad) batteries. As with most rechargeable NiMH batteries, you may find that maximum capacity is reached only after a few full charge and discharge cycles.
