Dr. Battery MPL08271P-24 4 Cell 14.8V 2200mAh laptop battery

Replacement Battery for HP Laptops

The Dr. Battery MPL08271P-24 is a new 4-cell lithium-ion pack rated at 14.8V and 2200mAh. It replaces original HP batteries including part numbers 756745-001, 756746-001, G6E88AA, HSTNN-DB6I, HSTNN-DB6K, HSTNN-DB6L, HSTNN-LB6I, HSTNN-LB6J, HSTNN-LB6K and TPN-Q140. Compatibility spans HP ProBook 440 G2, 450 G2, 455 G2, ENVY 14t-u000, 15-k and 17-k series, and Pavilion 14-v, 15-p and 17-k models. Buyers who need a different voltage, cell count or form factor should verify their original battery before ordering.

Thermals Noise and Power Draw

Lithium-ion chemistry delivers stable 14.8V output with a 33Wh energy rating. The integrated smart control chip manages charging current to reduce heat during recharge and limits self-discharge when the laptop is idle. Built-in protection circuits guard against short circuit, overheat and overload conditions, keeping temperatures within normal operating limits for the supported HP chassis. No active cooling is required and the pack adds no audible noise to the system.

Upgrade From Worn Original Packs

This unit restores runtime lost to ageing cells in the original 4-cell 14.8V battery. The jump is worth it when the existing pack no longer holds a useful charge or triggers sudden shutdowns under load. It matches OEM capacity and voltage exactly, so no BIOS update or hardware modification is needed. Users requiring higher capacity than 2200mAh or a different cell configuration will need a separate solution not covered by this part number.
