Replacement battery for Asus VivoBook Flip 14

The Dr. Battery B31N1705 is a new lithium-polymer pack built for Asus VivoBook Flip 14, ZenBook UX331UA, UX460UA and Q405UA models. It restores runtime on compatible ultraportables that use the original B31N1705 cell. Buyers needing a different voltage or form factor should look elsewhere.

Voltage match at 11.4 V

The single specification that decides fit is the 11.4 V output. Your original battery must show the same voltage; a mismatch will prevent the laptop from charging or powering on. Confirm the figure on the old label before ordering.

41 Wh capacity for daily mobility

Rated at 3600 mAh and 41 Wh, the pack delivers a full day of light office work, web browsing and video playback on supported devices. Heavy multi-tasking or sustained loads will drain it faster, so keep a charger handy for long sessions.

Questions about this item

How long will the 41 Wh capacity actually run my laptop?

The 41 Wh rating means the pack stores 41 watt-hours of energy; real-world runtime depends on your laptop's power draw, screen brightness and workload, so a system drawing 20 W would last roughly two hours.

What connector does the B31N1705 use to attach to the motherboard?

The battery uses the proprietary multi-pin connector designed for Asus VivoBook Flip 14, ZenBook UX331UA, UX460UA and Q405UA models; it plugs directly into the matching motherboard header.

Will this pack fit inside my TP410UA chassis without modification?

Yes, the B31N1705 is built to the exact dimensions of the original Asus battery for the listed VivoBook Flip 14 and ZenBook models, so it seats in the stock battery bay with the original screws.
