One of our staffers tested USB Cell size AA batteries. The directions on the pack of two recommend charging the batteries using the USB ports on a computer for five to seven hours prior to use.
He charged each for five hours and put them in a wireless mouse. He left the mouse on for one week with heavy use during the day and the mouse was still going strong at the end of the week.
The package suggests the batteries might not fit into some tight spots, but for general use -- especially in computer or game devices -- they seem to work well. He gives them a thumbs up.
