This comprehensive guide helps Australian and New Zealand users identify compatibility, recognise replacement signs, and make an informed purchase decision.

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 use HP’s official support website with your laptop serial number. The HP CS03XL 46Wh is designed specifically for the models listed and ensures optimal performance.
When to replace
Replace your battery when it shows significant capacity loss (typically after 2-3 years of regular use), physical damage, swelling, or if it no longer holds sufficient charge for your needs. In AU/NZ conditions, lithium-ion batteries typically last 300-500 charge cycles before noticeable degradation.
Installation guide (overview)
1. Power off laptop and disconnect charger
2. Remove the bottom panel (consult your model’s service manual)
3. Disconnect old battery connector
4. Remove mounting screws (if applicable)
5. Install new HP CS03XL 46Wh battery
6. Reconnect connector and replace panel
7. Charge fully before first use
Usage & care tips
• Avoid frequent full discharges – partial charges are better for lithium-ion batteries
• Store in cool, dry conditions (15-25°C ideal)
• Don’t leave laptop plugged in constantly at 100% charge
• Use original or authorised HP chargers
• Calibrate battery every 2-3 months by fully discharging then charging
Safety & recycling in AU/NZ
Never attempt to open or modify the battery. Damaged batteries should be taken to authorised e-waste recycling centres. In Australia, check with your local council for battery recycling options. In New Zealand, use the Recycle-more programme. Never dispose of lithium-ion batteries in household waste due to fire risk.
