If you don't plan on using the Power Tool Battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, Ni-MH, and Li-ion batteries will self-discharge during storage; remember to recharge the batteries before use.<br> 4. Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks.<br>
