6. Usage and Charging
To optimize battery performance and lifespan, follow these guidelines:
- Initial Charging: For new batteries, discharge the battery to approximately 5% (do not fully drain to 0%) before fully charging. Repeat this charge and discharge cycle 3-4 times to condition the new battery.
- Regular Charging: Avoid completely draining the battery before recharging.
- Adapter Connection: Do not leave the adapter connected for extended periods after the battery is fully charged, as this may negatively impact battery life.
7. Maintenance and Storage
Proper maintenance and storage can extend the life of your battery:
- Regular Discharge/Charge: Fully discharge and charge the battery every other month if not in regular use to maintain its health.
- Storage: If storing the battery for an extended period, ensure it is partially charged (around 50%) and stored in a cool, dry place away from direct sunlight and extreme temperatures. Do not store the battery for too long when not in use.
- Avoid Physical Damage: Do not subject the battery to human impact, disassembly, squeezing, or piercing.
- Environmental Conditions: Avoid using or storing batteries in environments with extremely high or low temperatures. Do not place them near ignition sources.
