1. Li-ion batteries: Have no "memory effect," so you dont need to fully discharge them before charging. Overcharging (keeping them at 100% for long periods) can degrade their health.
2. Avoid full charges and discharges: Keep the battery level between 20% and 80% as much as possible. Studies show that Li-ion batteries degrade faster when frequently charged to 100% or drained below 20%.
3. Unplug When Not Needed. Dont leave your laptop plugged in indefinitely after it reaches full charge.
4. Avoid Extreme Temperatures(ideally between 10°C and 30°C).
1. Charge your laptop in a cool, well-ventilated environment. High temperatures (e.g., leaving it in a hot car) can damage the battery even while charging.
2. In daily life, manage power settings. On Windows: Go to Settings > System > Power & battery and adjust the power plan to prioritize battery life (e.g., set the screen to dim after a short period, enable "Battery saver"). On macOS: Go to System Preferences > Battery and use "Low Power Mode" when running on battery.
3. Reduce power consumption, close unused apps.
1. Calibrate the Battery (Occasionally)
Some laptops may need periodic calibration to ensure the battery level indicator is accurate.
How to calibrate: Discharge the battery to around 10%, then charge it to 100% without interrupting the process. Do this once every 36 months (no need to do it frequently).
2. Check Battery Health
On Windows: Use the command powercfg /batteryreport to generate a battery report and view its capacity and wear level.
On macOS: Go to System Preferences > Battery > Battery Health to see if your battery needs replacement.
Yes, all of our laptop battery is li-ion or lithium-polymer battery, definitely rechargeable, but be sure to charge with the original AC adapter.
