How to check compatibility
Verify your laptop model matches our compatible list above. Check your current battery’s part number (usually printed on the battery itself) or look up your laptop’s model number (found on the bottom case or in system information). Cross-reference with our tables to ensure perfect fit and performance.
When to replace
Replace your battery when runtime drops below 50% of original capacity, typically after 2-3 years of regular use. Other indicators include the battery not charging to 100%, sudden shutdowns at 20-30% remaining, or physical swelling. In Australia and New Zealand’s climate, batteries may degrade faster due to temperature fluctuations.
Installation guide (overview)
Power down your laptop and disconnect all cables. Remove the bottom case screws (keep them organised). Gently disconnect the battery connector from the motherboard. Remove any securing screws or tape. Install the new battery, reconnect the connector, and reassemble. Always consult your device’s service manual or seek professional assistance if unsure.
Usage & care tips
For optimal battery life in AU/NZ conditions: Avoid extreme temperatures (ideal range 15-25°C), don’t leave your laptop in hot cars. Calibrate monthly by charging to 100% then discharging to 5%. Use authorised chargers only. Store at 40-60% charge if not using for extended periods.
Safety & recycling in AU/NZ
Never puncture or disassemble batteries. Dispose of old batteries at authorised collection points – most electronics retailers in Australia and New Zealand offer free battery recycling. Do not place in household rubbish. In case of battery leakage, avoid contact with skin and ventilate the area.
