Verify your laptop model matches one listed in our compatibility table. Check your current battery part number against our reference list. For additional confirmation, consult your laptop’s documentation or use Lenovo’s official support tools.
When to replace
Replace your battery when you notice significant performance degradation, typically after 2-3 years of regular use. Immediate replacement is necessary for any physical damage, swelling, or safety warnings from your system.

Power down your laptop completely and disconnect from power. Remove the bottom cover using appropriate tools. Disconnect the old battery connector and remove mounting screws. Install the new battery, reconnect the connector, and reassemble. Always follow manufacturer guidelines for safe installation.
