Replacement battery for legacy VAIO laptops

This 2.4 V Ni-MH pack replaces the original battery in several Sony VAIO models including PCG-VX88 VGN-A260 PCG-C1XE PCG-R505TZCP PCG-Z505GR/K PCG-Z505P and PCG-GRX500P. It matches the 20 mAh capacity and 0.05 Wh energy rating of the factory cell. The compact 31.07 x 12.04 x 4.4 mm form factor weighs 28.0 g and fits the original compartment without modification.

Upgrade from depleted or swollen original cells

The unit substitutes part numbers PCG-91111M FL2/V11H-WR 2/V20H 2/V15H and Varta 2/V30H when the factory battery no longer holds charge or shows physical swelling. The jump is worth it when the laptop runs only on AC power or shuts down instantly after unplugging. Built-in overcharge over-discharge over-voltage and short-circuit protection helps extend the new pack’s usable life.

Limited by Ni-MH chemistry and low capacity

The 20 mAh rating delivers only brief backup time so the battery suits CMOS retention or short bridge power rather than mobile use. Ni-MH cells self-discharge faster than lithium types and require periodic cycling to maintain capacity. The 2.4 V output is fixed and cannot support higher-voltage systems or fast-charge protocols.
