How to check compatibility
Verify your laptop model matches one of the compatible models listed above. Check your current battery’s part number (usually printed on the battery) against our reference list. For HP EliteBook X360 1020 G2s models, ensure you have the correct battery variant for your specific configuration.
When to replace
Replace your battery when you notice significant performance degradation, typically after 2-3 years of regular use. Most lithium-ion batteries maintain about 80% capacity after 300-500 charge cycles. If your laptop shuts down unexpectedly or won’t operate without being plugged in, replacement is urgent.
Installation guide (overview)
Power down your laptop completely and disconnect from power. Remove the bottom panel (usually requires a Phillips screwdriver). Disconnect the battery connector from the motherboard. Remove any securing screws and carefully lift out the old battery. Install the new HP ET04XL battery, reconnect the connector, and reassemble. Always consult your device’s service manual for detailed instructions.
Usage & care tips
For optimal battery life: avoid extreme temperatures (ideal range 15-25°C), don’t leave your laptop plugged in constantly, perform occasional full discharge cycles, and store in a cool, dry place if not using for extended periods. Keep your battery between 20-80% charge for daily use to maximise lifespan.

In Australia and New Zealand, lithium batteries must be recycled properly. Do not dispose of in household waste. Many electronics retailers offer free battery recycling services. Check with your local council for authorised battery recycling centres. Damaged or swollen batteries should be handled with care and recycled immediately.
