Verify Your Original Part Number Before Ordering

Check the label on your current battery for one of the listed part numbers such as 687945-001, 687517-171 or 696621-001. Also confirm the voltage reads 14.8V and the capacity shows 52WH. This pack is not suitable for models requiring a different voltage or cell count.

Direct Swap Restores Mobile Runtime

The battery installs into the existing compartment without extra cables or adapters. It frees the ultrabook from permanent mains tethering for mobile work. Buyers needing a higher capacity pack or a different form factor should look elsewhere.

Questions about this item

Does the BT04XL battery arrive as a single unit or do I need to buy a charger or screws separately?

The listing describes one 4-cell 52 Wh 14.8 V battery designed to replace the BT04, BT04XL, BA06 and BA06XL series; no charger, cables or mounting hardware are mentioned.

The title lists several HP part numbers — which one should I match to my EliteBook Folio 9740 or 9740m?

Check the label on your existing battery; if it shows 687945-001, 687517-171, 696621-001, BA06, HSTNN-IB3Z, BT04, BA06XL, H4Q47AA, H4Q48AA or HSTNN-I10C this unit is a direct replacement.

What does the 52 Wh rating actually give me in daily use on a 9740 Ultrabook?

A 52 Wh pack at 14.8 V supplies roughly 3.5 Ah, so typical office workloads on the Folio 9740 series should yield several hours of runtime before needing a recharge.
