Replacement battery for Acer Chromebook 11

This Cameron & Co DS-CS-ACC720NB lithium-polymer battery replaces the original AP13J3K and AP13J4K units in listed Acer Chromebook 11 and 14 devices. It supplies 3.95 Ah capacity in a black casing. The part fits a wide range of C720, C720P, C732, C732T, C740, C771 and C771T models as well as the Chromebook 14 CB3-431 series.

Direct-fit design limits use to listed Chromebooks

The battery is built to the exact mechanical and electrical specification of the OEM packs it replaces. It will only operate in the Acer Chromebook models named in the compatibility list. Builders or repairers working on other laptop brands or on Acer models outside that list cannot use this unit.

Upgrades worn-out original packs in supported

This unit replaces a depleted or failing factory battery in the compatible Chromebook 11 and 14 machines. The jump is worth it when the original pack no longer holds a useful charge or shows swelling. It is not for users needing higher capacity than 3.95 Ah or a different form factor.

Questions about this item

Which capacity should I pick for my Acer Chromebook 11 C720P?

The battery is supplied as a single 3.95 Ah unit, matching the original AP13J3K specification for the C720P and related 11-inch models.

What does 3.95 Ah mean for daily runtime on a Chromebook 14 CB3-431?

It delivers the same charge capacity as the factory pack, so a full charge typically lasts a full school or work day on supported 14-inch Chromebooks.

What connector standard does the DS-CS-ACC720NB use and what does it limit?

It uses the proprietary Acer multi-pin connector found on Chromebook 11 C720, C732, C740 and C771 series, limiting fitment to those exact chassis.
