4. Upute za rad
To get the best performance and lifespan from your battery:
- Punjenje: Connect your laptop to the AC adapter. The laptop's operating system or indicator lights will show the charging status.
- pražnjenje: Use the laptop on battery power until the charge level is low (e.g., 10-20%) before recharging. Avoid letting the battery fully discharge to 0% frequently, as this can reduce its lifespan.
- Kalibriranje: Occasionally, it is beneficial to perform a battery calibration. This involves fully charging the battery, then using it until it completely drains and the laptop shuts down, and finally recharging it to full capacity. This helps the battery management system accurately report the charge level.
5. Održavanje
Pravilno održavanje može produžiti vijek trajanja vaše baterije:
- Skladištenje: If storing the battery for an extended period (more than a month), ensure it is charged to approximately 50-70% and stored in a cool, dry place away from direct sunlight and extreme temperatures.
- Temperatura: Avoid exposing the battery to extreme heat or cold, as this can degrade performance and lifespan.
- Čišćenje: Periodically clean the battery contacts with a dry, soft cloth to ensure good electrical connection.
- Avoid Full Discharge: Do not allow the battery to remain fully discharged for long periods, as this can lead to irreversible damage.
