Recommendations

Store the battery in a cool, dry place and avoid extended exposure to high temperatures. For optimal lifespan, avoid keeping the battery at full charge or fully depleted for prolonged periods; regular partial discharges and recharges are recommended. If the laptop will not be used for an extended period, store the battery at around 40–60% charge and perform periodic top-ups to prevent deep discharge.
