We have avoided selling rechargeable batteries because we just really didn’t feel like the technology currently available gave good value to the customer. The combination of the cost, the decreased battery life over time, and the inability to predict performance over time has meant that our primary battery customers-those who use batteries in wireless microphones-couldn’t count on rechargeables to dependable meet their needs.
While we still don’t recommend rechargeable batteries for wireless mics, I just came across a rechargeable battery that may be just too cool to pass up.
The USB Cell from Moxia Energy, a British company, uses a computer USB port to recharge a AA battery. What could be handier than a battery that can be recharged while you work and doesn’t require a dedicated charger. While this battery may not have a discharge rate that is reliable enough for a wireless mic, there are lots of applications where it would be great.
People who travel with lots of electronic devices can now leave the battery charger at home and walk right by the overpriced batteries at the airport kiosk.
Unlike most rechargeable batteries that must be fully discharged, the USB cell can be inserted into a computer port for just a few minutes for a quick “top off”.
This item could save tons of money for gamers, and anyone who travels with both a computer and an MP3 player or radio that uses AA batteries. Cameras, flashlights and remote controls can all use the USB Cell.
We are in contact with the UK manufacturer, in hopes of becoming a US distributor. Check back here to see if we can make this available.
