Questions about this item

How can I confirm the Dr. Battery MPL08224P-27 is working correctly after installation?

After fitting the 6-cell 10.8V 4400mAh pack, the laptop should recognise the battery immediately, show a charging icon, and report roughly 48 Wh capacity in the OS power meter.

What comes with the Dr. Battery MPL08224P-27 and what must I source separately?

The box contains only the replacement battery itself; no tools, screws, or AC adapter are included, so have a suitable screwdriver ready for the swap.

Which Dr. Battery version should I choose for my HP EliteBook 8440p?

Select the MPL08224P-27 — it is the 6-cell 10.8V 4400mAh model listed as compatible with the 8440p and matching part numbers HSTNN-I44C, HSTNN-I45C, HSTNN-IB68 and HSTNN-IB69.
