Compatible replacement battery
The KingSener HK04XL is a new lithium-ion battery built for HP EliteBook X360 1030 G7 G8 and X360 1040 G7 G8 convertibles. It replaces part numbers HK04054XL, HSTNN-IB9H, HSTNN-IB9J, L82391-005, L82391-006, L82391-007, L83796-171, L84352-005, L79376-1B1 and L79376-1B2.

Capacity and voltage
This unit delivers 78.5 Wh at 7.72 V, while the manufacturer specification also lists a 54 Wh rating at 7.7 V for the same model family. Buyers who need the higher 78.5 Wh design capacity should verify the original battery label before ordering. The cell chemistry is Li-ion and the pack is assembled with high-quality cells and PCB.
Thermals and power behaviour
Normal use keeps the battery within standard laptop thermal limits; no active cooling is required beyond the notebook's own system. The supplier advises a full charge and discharge cycle two or three times on first use to stabilise capacity. Storing the pack above 80 % charge for long periods or exposing it to hot, humid environments will accelerate degradation.
