Compatible replacement battery

The POWER-FENG 33Wh A31N1719 is a new lithium-polymer laptop battery rated at 11.1V and 3000mAh. It replaces the original Asus A31N1719 pack and fits models such as the X507LA, R507UA, R507UB, R507MA, X507UB and X507UA. The black casing matches the stock appearance.

Upgrade from a worn original

This unit replaces a depleted or failing factory battery that no longer holds a useful charge. The jump is worth it when runtime has dropped sharply, the system throttles on battery power or the old pack shows physical swelling. It restores the 33Wh capacity the notebook was designed around.

Fits straight into the existing bay

The battery slots into the standard compartment without adapters or cable changes. It uses the stock connector and mounting points so the laptop chassis, cooling layout and power-management firmware remain untouched. No extra hardware is required to regain full mobile operation.
