Dr. Battery MPL08341P-03 replacement laptop battery

This Dr. Battery MPL08341P-03 is a new lithium-polymer replacement for HP Pavilion 14-bf, 14-bk, 14-cd, 15-cc, 15-cd and 15-ck models. It also fits the Pavilion x360 14-cd convertible. The pack replaces original part numbers including 920046-541, 920070-855, HSTNN-LB7J, HSTNN-LB7X, HSTNN-UB7J and TF03XL. Buyers with other HP series or non-listed Pavilion chassis cannot use this unit.

Capacity and voltage delivered

The cell operates at 11.4 V with a rated capacity of 3400 mAh, while the manufacturer highlights a nominal 11.55 V and 3470 mAh for 41.7 Wh. A built-in smart control chip manages quicker charging, lower power consumption and longer discharge time. Integrated protections guard against short circuit, overheat and overload conditions. No external software, drivers or calibration tools are bundled.

Build quality and daily handling

The black polymer enclosure matches the OEM form factor so it seats in the existing battery bay without adapters or case modification. Internal connectors align with the original socket for a direct plug-in fit. One-year manufacturer warranty covers defects. Users needing higher watt-hour capacity, a different voltage or compatibility with earlier or later Pavilion generations will need a different battery.

Questions about this item

Will the lithium-polymer cells need replacement after a certain number of charge cycles?

The lithium-polymer cells are rated for typical notebook cycle life; capacity will gradually decline after several hundred full charges, at which point a new battery restores original runtime.

What limits continuous discharge before the protection circuit intervenes?

The built-in smart control chip monitors current and temperature, cutting output if draw exceeds safe thresholds or the pack overheats during sustained heavy loads.

How much heat does the pack generate when the laptop runs all day on battery?

Normal operation produces only modest warmth; the polymer chemistry and onboard protection keep temperatures low enough that the laptop's own cooling handles any extra heat.
