By avoiding unnecessary charge/discharge cycles and using a compatible charging device you can help prevent premature aging of your rechargeable battery. Also, don’t charge the battery (unless you have to) if the temperature is approaching 100 or below 32 Fahrenheit. In addition, dropping the flashlight can damage the battery, so always keep a firm grip on your light. Finally, if you’re not going to use the flashlight for a while don’t put it away fully charged as this could damage the battery.\r
