Battery for HP EliteBook X360 1020 G2

This lithium-ion replacement battery delivers 49.81Wh at 7.7V for the HP EliteBook X360 1020 G2 convertible notebook. It matches the original ET04XL, 915030-1C1, 915191-855 and HSTNN-IB7U part numbers. The unit is built with Grade A cells for long-lasting performance. It suits owners who need a direct swap for a worn-out power pack.

Thermals and power draw in normal use

The pack operates at the factory voltage of 7.7V and supplies 49.81Wh of energy during typical workloads. Lithium-ion chemistry keeps self-discharge low when the notebook is asleep. No active cooling is required because the battery sits inside the chassis. Heat output stays within the laptop's original thermal design.

Initial conditioning and usage reminders

The battery ships with a partial charge; the maker advises a full discharge followed by a complete charge before regular use. Two full cycles from 100% down to 1% help the internal PCB recalibrate capacity. Avoid deep discharge during daily operation and do not store the pack unused for long periods. Keep the unit away from fire or high heat sources for safety.

Questions about this item

How do I install the ET04XL battery in my HP EliteBook X360 1020 G2, and what step is often missed?

Open the laptop case, disconnect the old battery connector, connect the new ET04XL matching the cable length and connector type, then secure it. The step people miss is checking the connector location and cable length against the original before fitting.

What maintenance will the ET04XL battery need later?

Fully charge to 100% and drain to 1% twice when new to recover capacity. Avoid completely draining during regular use, and do not store unused for long periods.

What limit appears first under sustained use of the ET04XL battery?

The 49.81Wh capacity sets the runtime limit; the 7.7V output and 6470mAh rating define the energy available before recharging is required.
