Nigel's Eco Store > Travel and Wind Up › Eco Travel Products › Rechargeable batteries AA Rechargeable batteries (pair) - recharge them from your laptop's USB portUSBCELL is a revolutionary award-winning new rechargeable AA battery. By opening the cap and plugging into a USB connector, you can recharge them pretty much anywhere there's a USB socket. USBCELL can be used in any device needing an AA battery. By making it easier to recharge batteries, it means fewer disposable batteries get made and thrown away, and so is better for the environment.

More information
You can recharge a USBCELL in any accessible powered USB socket; for example in computers or USB hubs. Once connected, you will see a small green light comes on at the USB plug end of the battery. This shows that the battery is charging. The built-in intelligent charger controls the charging process: When the battery is nearly full the light will start flashing (top up mode) and then will switch off when the battery is fully charged. 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. It's OK to top up; or just partially charge USBCELL if you need the power in a hurry: Ni-MH 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. Suitable USB sockets Most USB sockets are suitable, but occasionally a device will have a recessed or difficult-to-access USB socket: If the battery doesn't plug in easily, don't try to force it. Some (un-powered) USB hubs don't provide enough power to fully charge more than one USBCELL at a time. Use powered USB sockets or connect directly where possible. Can be used with ordinary NiMH chargers The preferred charging method is via USB, however with the cap on USBCELL works just like a normal Ni-MH battery and can be charged in an ordinary AA Ni-MH charger. Do not charge with super-fast chargers (rated over 600mA) that charge batteries in less than 2 hours. The USBCELL is not designed to work with these chargers. Check your charger’s manual before charging. Make sure that the batteries are properly connected: the positive terminal (green cap) must be at the correct end. It is normal for the USBCELL to get warm during charging but should never get so hot that it cannot be touched; If they seem to be getting too hot disconnect the charger. Not what you're after?
