How to check compatibility
Verify your laptop model matches one in our compatibility table above. Check your current battery’s part number (usually found on the battery label) against our reference numbers. For Australian customers, ensure your device was originally sold in the AU/NZ region for optimal performance.
When to replace
Replace your battery when runtime drops below 2 hours, charging becomes unreliable, or physical damage is visible. Most Lenovo batteries last 2-3 years with regular use in Australian conditions.
Installation guide (overview)
Power off your laptop and disconnect all cables. Remove the bottom cover (consult your user manual for specific instructions). Disconnect the old battery connector and remove any securing screws. Install the new battery, reconnect the connector, and reassemble. First charge should be for at least 4 hours.
Usage & care tips
Store batteries at room temperature (15-25°C). Avoid complete discharges – recharge when battery reaches 20%. Don’t leave your laptop plugged in constantly. For Australian conditions, avoid exposing batteries to direct sunlight or temperatures above 35°C.
Safety & recycling in AU/NZ
This battery meets Australian safety standards. Never attempt to open or modify the battery. Dispose of old batteries at authorised recycling centres – most electronics retailers in Australia offer free battery recycling services.
