Questions about this item

Should I pick the 4000 mAh version or is there a higher-capacity option for my EliteBook 840 G2?

This model is supplied at 4000 mAh and 11.1 V. The listed part numbers do not show a higher-capacity alternative, so this is the capacity available for the G1 and G2 series.

What does the 11.1 V rating mean for daily runtime on my ZBook 15u?

The battery delivers 11.1 V nominal (10.8 V compatible) with a 4000 mAh capacity. In practice this provides a full day of typical office work on supported ZBook 15u models before recharge is needed.

Does the CM03XL use a proprietary connector or a standard laptop battery interface?

It connects through the standard internal battery connector used by the listed HP EliteBook and ZBook models. The replacement matches the OEM form factor and pin-out for direct installation.
