AC14B8K / AC14B18J Battery Step-by-Step Installation Guide

1. Open the Laptop:
   Power off the laptop. Turn it over and remove all Phillips screws from the bottom case. Note: Some screws may be hidden under rubber feet.

The installation difficulty of the AC14B8K is moderate. Although it doesn’t use a strong adhesive, it requires removing the entire back cover. 

Q: How to identify if your battery is an AC14B8K?

Laptop Maintenance Tips: -H2

1. New battery: For using a new battery, you’d better try a few cycles of discharging to 5%. then charging up to 95%. So that it can be activated completely
2. Overuse: Do not always run a battery to 0%, as this would shorten its 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.
