How to use

Before first use, fully charge the battery with the laptop's original AC adapter while the system is powered off or in a suspended state. Install the battery by powering down the notebook, removing the old battery according to the device manual, and inserting the replacement until it clicks into place. After installation, verify battery detection in the operating system and allow a full charge–discharge cycle to calibrate the battery gauge for more accurate runtime reporting.

Usage recommendations

Use the battery with supported Lenovo ThinkPad models and the original charger. Avoid exposing the battery to extreme temperatures, moisture or physical shock. For optimal lifespan, store the battery at around 40–60% charge if not used for extended periods, and perform periodic charge cycles if the laptop remains unused for months.
