Materials and Care Instructions

Constructed with high-quality Grade A Lithium-Ion cells housed in a durable ABS plastic casing. To maximize the lifespan of your new battery, it is recommended to perform a full charge and discharge cycle upon first use. For long-term health, avoid frequent full discharges to 0% and try to keep the battery level between 20% and 80% for daily use. If storing the laptop for an extended period, discharge the battery to around 50% and store it in a cool, dry place.
