LXHY B31N1726 48Wh Replacement Battery

This lithium-ion battery replaces the original B31N1726 pack in compatible ASUS TUF Gaming laptops. It delivers 11.4V and 48Wh capacity for models across the FX504 FX505 A15 FA506 A17 FA706II FX80 and FX86 series. The black casing matches the factory appearance.

Sustained runtime and cycle life

Rated at 4240mAh the cell provides up to 500 recharge cycles over its service life. Voltage remains stable at 11.4V during extended gaming or work sessions so performance does not drop off as the charge depletes. The lithium-ion chemistry holds charge well when the notebook is stored between uses.

Verify part number and connector before ordering

Confirm the original battery carries one of the listed part numbers such as B31N1726 B31N1726-1 B31BN91 A41LK9H or 3ICP7/60/80. Check that the laptop model appears in the supported FX504 FX505 A15 FA506 A17 FA706II FX80 FX86 families. Buyers whose machines use a different voltage or form factor cannot use this pack.

Questions about this item

Does the 48Wh battery generate noticeable heat during long gaming sessions?

The 11.4V lithium-ion cell runs at standard laptop thermals; heat output matches the original pack and is managed by the notebook’s own cooling system.

Which connector does the B31N1726 use so I know it fits my motherboard?

It uses the same multi-pin connector as the original Asus B31N1726, B31N1726-1 and B31BN91 packs listed for the FX504, FX505 and FA506 series.

Will this 48Wh pack work in my older FX504GD that currently holds a 42Wh battery?

Yes, the 11.4V 48Wh unit is a direct replacement for the FX504GD and other FX504 models; the higher capacity simply adds runtime without changing voltage or fit.
