Drop-in replacement for TP510 series

The KingSener B31N1708 is a 42WH lithium-ion battery built to 11.52V for Asus VivoBook Flip TP510UA, TP510UF and TP510UQ models. It matches the original part number and fits the internal bay without modification. Owners of these convertibles can restore factory runtime with a direct swap.

Steady discharge over a workday

Rated at 3653mAh, the pack delivers consistent voltage through long sessions rather than peaking for a few minutes. Li-ion chemistry holds output stable as capacity drains, so the laptop avoids sudden throttling or shutdown when the charge drops low. The 11.52V nominal rating keeps the power subsystem in its design envelope.

Replaces an exhausted or swollen original

This unit takes the place of a degraded B31N1708 cell that no longer holds charge or shows physical swelling. The upgrade is worth it when the laptop cannot finish a typical meeting or commute on battery alone. It is not for users needing higher capacity than 42WH or a different voltage platform.

Questions about this item

Does the 11.52 V 42 Wh lithium-ion cell run hot or draw extra power during all-day use?

The replacement cell matches the original 11.52 V 42 Wh rating, so thermal output and power draw stay identical to the factory battery under normal loads.

What must I already own for this B31N1708 pack to work in my laptop?

You need an Asus VivoBook Flip TP510UA, TP510UF or TP510UQ series chassis — the pack slots directly into the existing battery bay with no extra cables or tools.

Will the 3653 mAh capacity behave the same as the original battery in my older TP510 model?

Yes, the 3653 mAh / 42 Wh rating mirrors the OEM specification, giving equivalent run-time and charge cycles on any compatible TP510 series unit.
