GreenTech 53WHR replacement for EliteBook x360 830

This GreenTech battery replaces the original CX03XL pack in HP EliteBook x360 830 G7 and G8 convertibles. It delivers 11.55V and 4400mAh from a three-cell lithium-ion design. The unit is built for owners who need a direct swap when the factory cell no longer holds charge. Buyers with other EliteBook chassis or non-convertible models should verify the part number before ordering.

Three-cell lithium-ion limits runtime under

A 53WHR three-cell pack supplies less energy than larger six-cell alternatives, so heavy workloads will drain it faster. The 11.55V output matches the platform requirement, but capacity drops noticeably when the CPU and GPU run at high turbo states. Users who regularly work unplugged for full days may find the runtime insufficient without a charger nearby.

Black moulded housing fits the internal bay

The battery uses a black plastic shell shaped to the x360 830 internal compartment, so it seats flush and the latch engages cleanly. Connector pins align with the motherboard header, eliminating cable strain during insertion. The rigid case resists flex when the 360-degree hinge is rotated, and the cell pack is CE, FCC and RoHS certified for safety compliance.
