How to check compatibility
Verify your laptop’s compatibility by checking the model number on the bottom casing or in system information. Cross-reference with our compatibility tables above. For additional confirmation, check your current battery’s part number against our listed references.
When to replace
Replace your battery when you notice significant performance decline, typically after 2-3 years of regular use. Most batteries show reduced capacity after 300-500 charge cycles. If your laptop shuts down unexpectedly or won’t operate without being plugged in, replacement is recommended.
Installation guide (overview)
Power down your laptop completely and disconnect from power. Remove the bottom panel using appropriate screwdrivers. Carefully disconnect the old battery connector and remove any securing screws. Install the new battery, reconnect the connector, and reassemble. Always refer to your laptop’s service manual for detailed instructions.
Usage & care tips
For optimal battery life, avoid complete discharges and store between 20-80% charge when possible. Keep your laptop in temperatures between 10°C and 35°C. Calibrate your battery monthly by fully charging then discharging to maintain accurate power readings.
Safety & recycling in AU/NZ
Always purchase from authorised retailers to ensure safety standards. In Australia and New Zealand, dispose of old batteries at designated recycling centres. Never dispose of lithium-ion batteries in household waste due to fire risk and environmental concerns.
