How to check compatibility
Verify your laptop model matches our compatibility list above. Check your current battery’s part number or look for model information in system settings or on the original battery label.
When to replace
Replace your battery when runtime drops below 50% of original capacity, charging takes excessively long, or you notice physical changes like swelling. Most batteries need replacement after 2-3 years of regular use.
Installation guide (overview)
Power down your laptop completely. Remove the power adapter and any peripherals. Carefully remove the old battery following manufacturer guidelines. Align the new battery correctly and secure it in place. Allow full initial charge before first use.
Usage & care tips
Avoid extreme temperatures (ideal range 10°C to 35°C). Don’t leave your laptop plugged in constantly. Perform regular calibration cycles. Store in cool, dry conditions when not in use for extended periods.
Safety & recycling in AU/NZ
Never attempt to open or modify batteries. Dispose of old batteries at authorised recycling centres. In Australia, use Batteryback or similar programmes. In New Zealand, utilise official e-waste collection services.
