How to check compatibility
Verify your laptop model matches our compatibility list above. Check your current battery’s part number (usually printed on the battery) or use Lenovo’s official support centre tools to confirm your device specifications.
When to replace
Replace your battery when it holds less than 60% of its original capacity, shows physical damage, or causes performance issues. Most laptop batteries need replacement every 2-3 years with regular use.
Installation guide (overview)
Power off your laptop and disconnect all cables. Remove the bottom panel (consult your device manual for specific instructions). Disconnect the old battery connector and remove any securing screws. Install the new battery, reconnect the connector, and reassemble your device.
Usage & care tips
Avoid extreme temperatures (ideal range 10°C to 35°C). Don’t leave your laptop plugged in constantly – occasional discharge cycles help maintain battery health. Store in a cool, dry place if not using for extended periods.
Safety & recycling in AU/NZ
Never attempt to open or modify lithium-ion batteries. In Australia and New Zealand, recycle old batteries at authorised collection points – many electronics retailers offer free battery recycling services. Never dispose of batteries in household waste.
