Beisite C31N1816 50Wh 11.55V laptop battery for Asus ZenBook Flip 13 UX362 Q326FA

Direct replacement for ZenBook Flip 13

This 50Wh lithium-ion battery replaces the original C31N1816 unit in Asus ZenBook Flip 13 models including UX362, UX362FA, UX362FA-2B, UX362FA-2G and Q326FA series. It delivers 11.55V output and matches the 3ICP5/70/81 cell configuration. The black pack fits the internal chassis without modification. Owners of these ultraportables can restore factory runtime with a genuine form-factor match.

Upgrade when the original pack no longer holds

The jump is worth it when the original battery drains quickly, shuts down under load or shows swelling. This new 50Wh unit restores the designed capacity for the UX362 and Q326FA families. It replaces part numbers C31N1816, 0B200-03160000 and 3ICP5/70/81 directly. Users who need reliable all-day mobility on these 13-inch convertibles gain a fresh power source without adapter changes.

Limited to the listed Asus ultraportable series

The battery only fits the specific ZenBook Flip 13 models named in the compatibility list. It will not work in other Asus lines, larger ZenBooks or non-Asus laptops. The 11.55V voltage and 50Wh capacity are fixed by the cell layout and connector pinout. Buyers must verify their exact model number against the supported UX362 and Q326FA variants before purchase.
