48 Wh Li-polymer battery for Asus ROG Strix G15

This 48 Wh lithium-polymer pack replaces the B31N1726 unit in Asus ROG Strix G15 G512 and G531 laptops. It delivers 11.4 V and 4240 mAh in a black housing. The part suits owners restoring mobility to a supported notebook. Builders needing a different voltage or connector should look elsewhere.

Steady output through long sessions

The 48 Wh capacity is rated for sustained discharge rather than brief peaks, so runtime scales with the workload you actually run. Li-polymer chemistry maintains voltage stability as the charge drops, avoiding the sharp fall-off seen in worn cells. Thermal behaviour stays consistent during extended use because the pack fits the original bay without modification. Systems that demand higher watt-hours for all-day work will not reach their target with this unit.

Verify the exact model before ordering

Match your laptop model number against the supported list: G512, G531, FX505, FX506, FA506, FA706 and the FX705 series. Confirm the original battery carries part number B31N1726 and shows 11.4 V on its label. Check that the connector orientation matches the motherboard header in your chassis. Machines outside the listed series or with a different voltage rating will not accept this pack.
