Avoid recharging immediately after a full discharge. Allow it to cool for a few minutes to help prolong battery life. Do not constantly use high power mode, it will speed up degradation of the battery. Please store it dry, clean, moisture, away from heat and metal objects, store your battery at room temperature (68°F/20°C). Avoid using the cleaner with the battery flush to a surface. This will help it run cooler and prolong battery run time and life. Charge your battery at least once every 3 months if not using the battery.
