Dr. Battery 6-cell 4400mAh replacement

This Dr. Battery MPL15015P-12 is a new 6-cell lithium-ion laptop battery rated at 11.1V and 4400mAh. It replaces original Sony VAIO packs such as VGP-BPL2, VGP-BPL2A and VGP-BPL2B across numerous PCG and VGN series models. The black casing matches the factory colour of the supported notebooks. Buyers should verify their original part number against the listed compatibilities before ordering.

49Wh capacity for typical daily workloads

The 49Wh pack delivers enough energy for several hours of office applications, web browsing and video playback on compatible VAIO laptops. Runtime scales with screen brightness, CPU load and wireless activity, so intensive tasks such as gaming or rendering will drain the battery faster. The integrated smart chip manages charge cycles to optimise longevity and provides short-circuit, overheat and overload protection. Users needing all-day operation away from mains power may find the capacity limiting.

Passive cooling with built-in safety circuits

The battery relies on the laptop's own thermal design; it has no fan or active cooling of its own. In normal use the pack runs at ambient temperature thanks to the low internal resistance of the lithium-ion cells and the smart control chip that reduces power consumption during charging. Protection circuits guard against short circuits, overheating and overload without adding audible noise. The unit draws power only during charging and supplies it silently during discharge.
