Lithium-ion batteries work based on ion movement between negative and positive electrodes. A Lithium-ion Battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often. The inside temperature during operation rises to 45°C (113°F). Hence, avoid keeping Lithium Battery in full charge and in high-temperature status for a long time.
