One of the big problems with the wireless mouse is it’s battery life. A pair of AA alkalines will last for about 30 days or less, depending on usage. But if you want to get the most life out of your pointing device, Davetech over at Instructables has a practical solution: replace the AA battery housing with one designed for a rechargeable cellphone battery.
Because lithium-ion cellphone batteries provide longer life and recharge faster than regular cells, the end product is a much better wireless mouse. To learn the procedure just click HERE.
