How to check compatibility
Verify your laptop model matches our compatibility list above. Check your current battery’s part number (usually printed on the battery) or locate your laptop model number on the bottom casing or system information.
When to replace
Replace your battery when you notice significant performance decline, typically after 2-3 years of regular use. Most batteries maintain optimal performance for 300-500 charge cycles before capacity diminishes.

Power down your laptop completely. Remove the power adapter and any connected devices. Carefully remove the bottom panel using appropriate tools. Disconnect the old battery and install the new one, ensuring proper connection. Reassemble and charge fully before first use.
Usage & care tips
Avoid extreme temperatures – store and use between 10°C and 35°C. Don’t leave your laptop plugged in constantly. Perform regular calibration by fully discharging and recharging monthly. Keep battery contacts clean and free from dust.
Safety & recycling in AU/NZ
Never attempt to open or modify the battery. Dispose of old batteries at authorised recycling centres. In Australia, use Batteryback or similar programs. In New Zealand, utilise accredited e-waste collection services. Never dispose of batteries in household waste.
