How to use

Power down the laptop and remove any external power source before replacing the battery. Follow the laptop manufacturer’s instructions for safe removal and installation: remove the service cover or bottom panel if required, disconnect the old battery pack from its connector, and install the replacement so it seats securely. After installation, reconnect external power and allow the battery to charge to full before normal use; this helps the system recognize the new pack and report accurate charge levels.

Recommendations

Store and use the battery at room temperature when possible. Avoid prolonged exposure to high heat or humidity, and do not disassemble, crush or expose the battery to fire. For best long‑term performance, perform regular charge cycles and avoid keeping the battery at full charge for extended periods when storing the laptop. Use only the laptop manufacturer’s approved charger or a compatible adapter that matches the original charging specifications.
