Replacement Battery for Sony VAIO Fit and Flip

This Dr. Battery Professional Series unit restores power to Sony VAIO Fit 14A, Fit 15A, and Flip SVF series laptops. It replaces original batteries carrying part numbers BPS40 or VGP-BPS40. The lithium polymer cell delivers a nominal 15V for direct compatibility. Buyers must verify their original battery part number and voltage before ordering.

3170 mAh Capacity with Integrated Safety

The 3170 mAh rating supports typical business and everyday productivity workloads on supported VAIO models. Runtime scales with screen brightness, processor load, and peripheral use, so intensive tasks will drain the pack faster. Built-in circuitry guards against over-charge, over-discharge, overheating, and short-circuit conditions. The battery measures 8.0x1.5x0.8 and weighs 0.4.

Upgrade from Worn or Failed Original Packs

This unit replaces depleted factory batteries that no longer hold a useful charge or that trigger shutdown warnings. The jump is worthwhile when the original pack shows reduced runtime, swelling, or calibration errors. It is not suited for laptops outside the listed VAIO Fit and Flip series or for users needing a higher-capacity alternative than 3170 mAh.
