Compatible replacement battery

The PISKEKAT AP13J4K is a new 11.4V 45Wh laptop battery built for Acer Chromebook 11.6" models including the C720, C720P, C740 and CB3-532 series. It replaces part numbers AP13J3K, KT.00304.001, KT.00303.001 and KT.00303.011. The black unit ships with an instruction manual.

Cord-length check required

This version has a 4cm connector cord; buyers must open the back cover and verify their original battery uses the same 4cm length before ordering. Units with 2.5cm or 6cm cords will not fit. The battery suits owners of the listed Chromebook models needing a direct voltage and capacity match.

Voltage and capacity match

The decisive specification is the 11.4V 45Wh rating paired with the 4cm cord length. Only devices that originally shipped with this exact voltage, capacity and cord geometry will accept the part.

Questions about this item

Does the 11.4 V 45 Wh AP13J4K battery run hotter than the original during all-day use?

The replacement matches the original 11.4 V and 45 Wh rating, so thermal behaviour should be equivalent.

Must I already own an Acer Chromebook C720 or C740 series for this AP13J4K to fit?

Yes — it is compatible only with the listed C720, C720P, C740 and CB3-532 models.

Will the 4 cm cord on this AP13J4K connect to the motherboard in my older C720-2800?

The C720-2800 is in the supported list, but verify your original battery cord is also 4 cm before installing.
