How to check compatibility
Verify your laptop model matches our compatibility list above. Check the label on your current battery for the part number. For Australian and New Zealand customers, cross-reference with your original purchase documentation or use Lenovo’s official support website with your serial number.
When to replace
Most laptop batteries last 2-3 years with regular use. Replace when capacity drops below 60% or if you experience any safety concerns like swelling. In AU/NZ climates, extreme temperatures can accelerate battery degradation.

2. Remove bottom panel screws (keep organised)
3. Carefully disconnect old battery connector
4. Remove mounting screws and old battery
5. Install new battery and reconnect

Usage & care tips
• Avoid complete discharges – recharge at 20-30%

• Keep contacts clean and free from dust
Safety & recycling in AU/NZ
Never dispose of lithium batteries in household waste. Use dedicated battery recycling services available at most electronics retailers across Australia and New Zealand. Damaged or swollen batteries require special handling – contact your local recycling centre for guidance.
