Replacement battery for Asus TUF Gaming laptops
This 11.4V lithium-polymer pack replaces the original battery in compatible Asus TUF Gaming FX504, FX505 and FX80 series notebooks. It restores full mobile operation when the factory cell no longer holds a useful charge. The 44Wh capacity matches the original specification for these models.
Upgrading from a depleted or swollen original pack
A fresh cell eliminates sudden shutdowns, reduced runtime and the physical bulge that can stress the trackpad or chassis. The jump is worth it when the laptop still meets your performance needs but tethered use has become the only option. Two hardware revisions exist; verify the connector and clip layout on your old battery before ordering.
3900 mAh capacity for everyday workloads
The 44Wh rating delivers several hours of typical office, browsing or video playback on a healthy system. Heavy gaming, sustained CPU loads or high screen brightness will drain the pack faster and may require a mid-session recharge. Users needing all-day runtime without access to mains power should plan for an external power bank or a second battery.

Questions about this item
What battery connector and clip layout does the B31N1726 use for Asus TUF Gaming FX504 and FX505 models?
The supplier notes two versions exist; verify the clips and connector on your original battery match the replacement before fitting.
Which steps are required to install the 11.4 V 44 Wh lithium-polymer battery in a compatible Asus laptop?
Power off, disconnect the AC adapter, remove the bottom case screws, unplug the old battery connector, fit the new pack, reconnect, then reassemble — skipping the connector check is the common error.
When should the 3900 mAh Dr. Battery pack be replaced in an Asus FX504 or FX80 series laptop?
Replace it when run-time falls well short of the original 44 Wh capacity or the pack swells, whichever occurs first.
