How to check compatibility
Verify your laptop model matches exactly with our compatibility list above. Check the model number on the bottom label of your laptop or in system information. For Australian and New Zealand customers, ensure you’re purchasing from authorised retailers for warranty protection.
When to replace
Replace your battery when it holds less than 60% of its original capacity, shows physical damage, or causes system instability. Most laptop batteries last 2-3 years with regular use in typical AU/NZ conditions.
Installation guide (overview)
Power off your laptop and disconnect all cables. Remove the bottom panel using appropriate screwdrivers. Disconnect the old battery connector and remove mounting screws. Install the new battery, reconnect the connector, and reassemble. Always follow manufacturer guidelines for your specific model.
Usage & care tips
Avoid extreme temperatures – store between 15-25°C. Don’t leave your laptop plugged in constantly. Perform partial discharges rather than full cycles. Keep battery contacts clean and free from dust. Store in cool, dry conditions when not in use for extended periods.
Safety & recycling in AU/NZ
Never attempt to open or modify the battery. Dispose of old batteries at authorised recycling centres – most electronics retailers in Australia and New Zealand offer free battery recycling services. Do not dispose of in household waste due to environmental regulations.
