How to use

Power down the laptop and disconnect the mains adapter. Remove the original battery according to the laptop manufacturer’s instructions, then align and insert the Green Cell LE78 into the battery bay until it locks into place. Reconnect the mains adapter and charge the battery fully before the first use to ensure proper calibration. After installation, manage power settings in the operating system to optimise runtime as required.

Recommendations

For safe and long-lasting operation, use the laptop with the manufacturer-recommended charger, avoid extreme temperatures, and store the battery partially charged if not used for extended periods. Regular full-charge/discharge cycles are not necessary for LiPo chemistry; occasional calibration (full charge then discharge to ~20%) helps the battery meter remain accurate.
