Laptop Battery Usage and Maintenance Guide
I. Battery Usage and Maintenance Tips

Activation Method for New Batteries: After receiving a new battery (usually with an initial charge of approximately 50%), first discharge the battery to 10% - 20%, then fully charge it. Repeat this process 3 - 5 times to maximize the initial performance of the battery
Avoid Over-discharging: Do not discharge the battery to 0%, as this may damage the battery cells and accelerate battery aging. When the battery level is extremely low, the laptop may shut down suddenly
Charge in a Timely Manner: After the battery is exhausted, charge it promptly. If the battery is not charged for a long time, it may be damaged
Storage for Long-term Inactivity: If you plan not to use the laptop for a long time, charge the battery to more than 70% before storing it, and the optimal storage period should not exceed 3 months
Use the Battery Regularly: If you often use the laptop with the charger connected, it is recommended to use the battery power (i.e., disconnect the charger) at least once a week to maintain battery activity
Choose Compliant Chargers: Use original chargers or chargers from well-known brands. Poor-quality chargers will affect the normal charging of the battery and may even damage the battery
Maintain Device Heat Dissipation: Clean the fan dust regularly to improve the device's heat dissipation effect, reduce power consumption, and effectively extend the battery life
Explanation of Battery Level Fluctuations: During the battery discharge process, the remaining power percentage and estimated usage time may fluctuate up and down due to running different software, which is a normal phenomenon. Please focus on whether the actual usage time is within the normal range

II. Causes and Solutions for Laptop Battery Not Being Recognized

Loose Battery Connection: The battery may not be recognized due to loose installation. You can remove the battery and reinstall it, ensuring that the battery connector is tightly connected to the mot
