Replacement Battery for Asus TUF Gaming

This new lithium-ion battery replaces the original B31n1726 unit in Asus TUF Gaming FX504, FX505, FX80, FX86 and A15 series laptops. It delivers 48 Wh at 11.4 V using 4110 mAh cells. The pack weighs 10.8 ounces and ships in black.

Cable Length Limitation

The battery uses the short-cable variant; the long-cable version cannot be substituted. Buyers must open the laptop back cover to confirm which cable type their system requires before ordering. An incorrect cable will prevent installation.

48 Wh Capacity and Cycle Life

Rated at 48 Wh, the pack supports up to 500 recharge cycles over its lifetime. It suits daily mobile work and gaming sessions but will not extend runtime beyond the original factory specification. Heavy workloads will drain the charge faster than light use.

Does the 11.4V output work with every listed Asus TUF Gaming series?
