To maximize the lifespan of your new battery, we recommend the following:

1. Calibrate the battery upon first use: Fully charge it, then let it discharge completely before recharging to 100%.
2. Avoid exposing your laptop to extreme hot or cold temperatures.
3. For long-term storage, keep the battery charged to around 50% and store it in a cool, dry place.
4. Avoid frequent full discharges. It is generally better for Lithium-Ion batteries to perform partial discharges and frequent recharges.
