Laptop Maintenance Tips:

2. Overuse: Do not always run out of a battery to 0%, this would make it or usage life.
3. Charging sequence: When charging, first install the battery, then turn on the power. when fully charged, first cut off the power, then pull the power plug.
4. Long-term storage: Please store the unused battery fully charged. (Charge it once a month.) Do not store at low power to prevent reducing the lifespan of a battery
5. Charger: Do not replace the laptop adapter casually. If the original adapter cannot be applied due to malfunction or damage, please replace the models so as not to reduce the service life of the battery due to incompatibility.
