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 website with your serial number. All compatible models are clearly listed in our tables.
When to replace
Replace your battery when it holds less than 60% of its original capacity, shows physical damage or swelling, or fails to charge properly. Most laptop batteries last 2-4 years with regular use in Australian conditions.
Installation guide (overview)
Power off your laptop and disconnect from power. Remove the bottom cover (consult your model’s service manual). Disconnect the old battery connector and remove mounting screws. Install the new battery, reconnect, and reassemble. Always use proper anti-static precautions.
Usage & care tips
Avoid extreme temperatures – store between 15-25°C. Don’t leave your laptop plugged in constantly. Calibrate your battery monthly by fully charging then discharging to 10%. Keep contacts clean and avoid physical impacts.
Safety & recycling in AU/NZ
Never attempt to open or modify lithium-ion batteries. Dispose of old batteries at authorised recycling centres – most electronics retailers in Australia and New Zealand offer free battery recycling services. Never dispose in household waste.
