Compatible 48Wh replacement battery

This 11.4V Li-ion pack replaces the B31N1726 unit in select ASUS ROG Strix G531 and G512 series laptops. Grade A cells deliver up to 1000 recharge cycles over the battery life. Installation tools are included in the package. Buyers who need a different voltage or connector layout should verify the original part number first.

Sustained discharge and cycle stability

The cell chemistry supports repeated full cycles without rapid capacity fade during long work sessions. Built-in circuit protection guards against overcharge, over-discharge and short-circuit events under continuous load. If the pack is not recognised on first fit, reseat the connector and complete three to four calibration cycles from five percent to full charge. Systems requiring hot-swap capability or external charging docks are not supported by this design.

Proprietary connector and model match

The battery uses a model-specific interface that only fits the listed ASUS part numbers 31CP7, 31CP60 and 31CP80. No universal pinout or third-party adapter is provided, so the laptop chassis must accept the exact original form factor. Buyers who cannot confirm the B31N1726 code on their existing cell should not purchase this unit.
