When we designed the wireless HandShoe Mouse we wanted to provide as much freedom as possible. First of all you should be able to work with the mouse for several weeks before re-charging the battery and secondly you may want sufficient distance between the mouse and the communication antenna.
So we fitted a large lithium ion battery and made sure the battery life is such, that you can use the HandShoe Mouse for many hours a day, seven days a week. Normally the battery is still not empty after four weeks. We advise you, however, to charge at regular intervals, for example once a week on the same day during lunch, as long as you keep your computer switched on. If you forget it and your battery is almost fully run down, you will be warned by a flashing light under the translucent scroll wheel. You then have to connect the mouse cable to charge the battery. You can continue using the mouse, as long as you leave the antenna in place for communication. When the battery is totally flat, you may have to wait a couple of minutes as the mouse needs at least some power to work.
