3. Remove the old battery, carefully connect the new battery to the mainboard, reinstall all the parts that have been removed earlier, and connect the wiring of the new battery.

1. New battery: Discharge the new battery to 10% (not 0%), then charging up to 95% and repeat 3-4 times to activate the maximum capacity.
2. Overuse: Do not always run out of a battery to 0%, that would damage the battery or shorten the 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.

1. Use a compatible charger: Always use a charger that matches your laptop's original specifications (same voltage and current parameters).

For subsequent charges, unplug the charger promptly after reaching full capacity to avoid prolonged charging while the battery is fully charged.
Note: If the battery exhibits severe heating, unusual odors, bulging, or other abnormalities during charging, immediately unplug the charger, shut down the laptop, and stop using the battery. Do not continue charging or using the battery.
