How to check compatibility
Verify your laptop model matches our compatibility list above. Check your current battery’s part number (usually found on the battery label) against our reference numbers. For HP Envy models, ensure your device matches the specific model variants listed.
When to replace
Replace your battery when it holds less than 50% of its original capacity, shows physical damage, or causes system instability. Most laptop batteries need replacement after 2-3 years of regular use in Australian conditions.
Installation guide (overview)
Power off your laptop and disconnect from mains power. Remove the bottom panel (consult your model’s service manual). Disconnect the battery connector and remove any securing screws. Install the new HP SG03XL battery, reconnect, and reassemble. First charge for 4-6 hours.
Usage & care tips
Avoid extreme temperatures – store between 15-25°C. Don’t leave your laptop plugged in constantly. Perform partial discharges rather than full cycles. Calibrate your battery monthly by fully charging then discharging to 10%.
Safety & recycling in AU/NZ
In Australia and New Zealand, lithium-ion batteries must be recycled through authorised collection centres. Never dispose of batteries in household waste. Check with your local council for battery recycling options. Damaged batteries should be handled by professionals.
