The lithium battery can be charged at any time, it is not necessary that all energy is exhausted before charging. The battery should be used within a range of operating temperatures. Otherwise, there may be a loss of properties, leakage and / or rust. The rechargeable battery should be used within a short period of time after recharging, as the battery may self-discharge during prolonged storage. If long-term storage is required, the battery, which is 50% to 60% stored in a voltage range, is best because storage at higher voltage can result in loss of performance. Do not immerse the battery in water or seawater. Store the battery in a cool, dry environment.
The battery should not be used near a heat source as a fire or heater. Use the charger specifically for charging. Do not interchange the position and the negative terminals. Do not connect the battery electrodes to a power outlet.
