Compatible HP ProBook and ZHAN 66 models

This 45Wh lithium-ion battery replaces part numbers RE03XL, RF03XL, HSTNN-UB7R and L32407-AC1 across ProBook 430, 440, 445, 450 and 455 G6 and G7 series. It also fits ZHAN 66 Pro 13, 14 and 15 G2 and G3 models. The cell chemistry is standard Li-ion with a black casing.

Check original part number and voltage tolerance

Verify that your current battery carries one of the listed part numbers such as 3ICP6/59/74, HSTNN-DB9A or L32656-005 before ordering. The replacement operates at 11.4V or 11.55V and the supplier notes both voltages are compatible with each other. Confirm the physical dimensions match your chassis since the compatibility list is non-exhaustive.

Steady discharge at rated capacity

The pack delivers 45Wh under continuous load rather than only in short bursts, supporting typical office workloads throughout the day. Lithium-ion chemistry maintains a stable voltage curve during extended use. A 12-month warranty covers defects in materials and workmanship.

Questions about this item

Does the package include any tools or cables, or just the 45Wh battery?

The package includes one 45Wh lithium-ion battery only; no tools, cables or adapters are supplied.

The listing shows RE03XL and RF03XL with 11.4V and 11.55V — which one should I pick for a ProBook 440 G7?

Both part numbers and both voltages are interchangeable; the supplier ships whichever is in stock and it will work in the ProBook 440 G7.

What runtime can I expect from the 45Wh capacity in a ProBook 450 G6 under normal office use?

A 45Wh pack typically delivers several hours of light productivity work; actual runtime varies with screen brightness, workload and battery age.
