Dr. Battery MPL08276P-01 4500 mAh 11.1 V laptop battery

Dr. Battery MPL08276P-01 replacement battery

The Dr. Battery MPL08276P-01 is a new lithium polymer battery rated at 11.1 V and 4500 mAh. It is built as a direct replacement for numerous HP EliteBook and ZBook models including the 740, 745, 750, 755, 840, 845, 850 and 855 series across multiple generations. An internal smart control chip manages charging and discharging while providing short circuit, overheat and overload protection. Buyers needing a different voltage or a higher capacity pack cannot use this unit.

Sustained discharge and thermal behaviour

The 50 Wh cell delivers consistent output during extended work sessions thanks to the smart chip that regulates power draw and lowers consumption. Built-in safeguards cut power if temperatures rise too high or a short circuit occurs, preventing damage to the laptop. The lithium polymer chemistry maintains stable voltage across the discharge cycle without the memory effect found in older chemistries. Users running continuous heavy loads should still monitor system temperatures as the pack has no active cooling of its own.

Installation steps and common pitfalls

Installation requires opening the laptop chassis, disconnecting the old pack and connecting the new one to the same header; no soldering is needed. The most frequent issue is ordering the wrong part — verify the original battery part number such as 716723-271 or 716724-141 and confirm the 11.1 V rating before purchase. Some EliteBook models share similar chassis but use different connectors, so visual comparison with the original battery is essential. A first full charge cycle helps the firmware calibrate the new capacity correctly.
