To maintain lithium batteries and ensure their longevity, here are some general guidelines to follow:

Avoid extreme temperatures: Lithium batteries should be stored and operated within a moderate temperature range. High temperatures can cause the battery to degrade, while extreme cold temperatures can reduce its capacity. It's best to keep lithium batteries between 20°C to 25°C (68°F to 77°F) for optimal performance.

Avoid deep discharges: Lithium batteries generally prefer shallow discharge cycles. It's recommended to avoid fully discharging the battery regularly. Instead, aim to keep the battery level between 20% and 80% for the majority of its usage. This will help prolong its lifespan.

Occasional calibration: To maintain accurate battery level readings, it's beneficial to calibrate the battery occasionally. Allow the battery to discharge completely (to around 0%) and then charge it to 100% without interruption. This process helps the battery's internal circuitry recalibrate and provide accurate readings.

Use the manufacturer's charger: Whenever possible, use the charger provided by the battery manufacturer or a charger specifically designed for lithium batteries. Using incompatible chargers can damage or reduce the battery's performance.

Avoid overcharging: Lithium batteries have built-in protection circuits to prevent overcharging. However, it's best not to leave the battery connected to the charger for an extended period after it reaches 100%. Frequent overcharging can degrade the battery's capacity over time.

Store at a partial charge: If you need to store lithium batteries for an extended period, it's recommended to keep them at a charge level between 20% and 60%. Storing batteries at full charge or discharged state for long periods can lead to capacity loss.

Keep battery cool during charging: While charging, it's advisable to keep the battery in a cool and well-ventilated area. This helps prevent excessive heat buildup during the charging process, which can be harmful to the battery.

Avoid physical damage: Handle lithium batteries with care and avoid subjecting them to physical shocks or impacts. Physical damage can compromise the battery's integrity and lead to safety hazards.

Remember that these guidelines are general recommendations, please read the product instructions carefully and follow the use recommendations.
