How to check compatibility
Verify your laptop model matches our compatibility list above. Check the label on your current battery for part numbers like 01AV436, 01AV400, or SB10K97593. You can also find your laptop model number on the bottom casing or in system information.
When to replace
Replace your battery when it no longer holds a sufficient charge for your needs, shows physical damage, or reaches 2-3 years of regular use. Most lithium-ion batteries maintain optimal performance for 300-500 charge cycles.
Installation guide (overview)
Power off your laptop and disconnect the charger. Remove the bottom panel (usually secured with screws). Disconnect the old battery connector and remove any mounting screws. Install the new battery, reconnect the connector, and reassemble. Always refer to your laptop’s specific service manual for detailed instructions.
Usage & care tips
Avoid extreme temperatures (ideal range 15-25°C). Don’t leave your laptop plugged in constantly – occasional discharge cycles help maintain battery health. Store in a cool, dry place when not in use for extended periods. Use only authorised chargers to prevent damage.
Safety & recycling in AU/NZ
Never attempt to open or modify the battery. Dispose of old batteries at authorised recycling centres – most electronics retailers offer free battery recycling services. In Australia, check with your local council for battery disposal options. In New Zealand, use designated battery recycling facilities.
