Replacement for HP EliteBook and ZBook models

This 11.1V 4500mAh lithium polymer battery replaces original HP units such as CM03XL, CM03024XL and 719941-002. It fits a wide range of EliteBook 740, 745, 750, 755, 840, 845, 850 and 855 series notebooks including G1 and G2 generations. The pack is built to OEM specification with an integrated smart control chip.

Installation is a standard battery swap

Power down the laptop, remove the bottom case screws and disconnect the old pack before fitting the new one. The connector orientation matches the original design so no adapter is needed. Common issues arise when the battery part number or voltage does not match the specific sub-model.

Verify the exact model number

Check the label on your current battery for the HP part number and confirm 11.1V output before ordering. Compatibility lists cover many variants but not every regional SKU. Buyers who need a different voltage or a higher capacity pack should look elsewhere.

Questions about this item

How do I confirm the 11.1V 4500mAh battery is working correctly after installing it in my EliteBook 840 G2?

The operating system should recognise the new pack, show a design capacity close to 50 Wh and charge to full without overheating or sudden shutdowns.

What comes in the box with the Dr. Battery MPL08276P-03 and is anything else needed for installation?

The replacement battery ships ready to fit; no extra cables, screws or tools are required beyond what the laptop already uses.

My original battery is labelled CM03XL — how do I pick the right version from the listed compatibilities?

CM03XL appears in the supported part-number list, so the MPL08276P-03 is the correct match for that original.
