Replacement battery for HP Pavilion x360 14-ba

This Dr. Battery MPL08340P-T01 unit replaces the original BK03XL cell in HP Pavilion x360 14-ba series laptops. It delivers 11.55V and 41.7Wh capacity using lithium polymer chemistry. The pack is built new and includes a one-year warranty from the manufacturer.

Sustained discharge with smart-chip protection

An internal control chip manages charging current and discharge pacing so output remains steady during long work sessions. The circuitry provides short-circuit, overheat and overload safeguards that keep the battery operating within safe limits over its service life. Lower power consumption during idle periods helps extend overall run time between charges.

Verify model number and voltage before ordering

Check the part number printed on your existing battery against the compatibility list that includes 916366-421 and 916811-855. Confirm the original cell is rated at 11.55V to match this replacement. Buyers whose laptop uses a different voltage or connector layout will need an alternative pack.

Questions about this item

How much heat does the 11.55 V 41.7 Wh lithium-polymer pack generate during a full day of use?

The battery runs at the same 11.55 V and 41.7 Wh as the original, so heat output matches the factory design and stays within normal laptop thermal limits.

What must I already own to install the MPL08340P-T01 replacement battery?

You need a compatible HP Pavilion x360 14‑ba series laptop and a small Phillips screwdriver to open the bottom case and swap the pack.

Will the 3470 mAh cell work reliably in an older Pavilion x360 14‑ba007ca that still has its original charger?

Yes, the 11.55 V output matches the original specification, so the existing charger and power management firmware recognise the pack without any changes.
