Replacement battery for Asus ZenBook U500 UX51

The Beisite C42-UX51 is a 14.8V 70Wh lithium-ion battery built to fit Asus ZenBook U500, U500V, U500VZ, UX51, UX51V and UX51VZ models. It replaces part numbers C42-UX51, 4ICP3/38/88 and 4ICP5/53/94. The black pack arrives new and includes a 12-month warranty.

Steady output through a full work session

Lithium-polymer chemistry delivers stable voltage across the discharge curve, so the notebook keeps its performance level without the sudden drops seen in aged cells. The 70Wh capacity supports extended use away from a wall outlet during typical productivity workloads.

Verify the exact sub-model before ordering

Check the label on the original battery or the laptop chassis for a part number such as C42-UX51, 4ICP3/38/88 or 4ICP5/53/94. This pack does not suit ZenBook variants outside the U500 and UX51 families, nor does it fit ultrabooks that require a different voltage or connector layout.

Will this replacement battery fit the same bay and connector as the original unit in my older ZenBook UX51VZ?
