Replacement battery for Acer Chromebook 11.6

This Li-ion replacement battery delivers 45Wh at 11.4V for Acer Chromebook 11.6" C720 and C740 series models. It matches part numbers AP13J3K and AP13J4K as well as original references KT.00304.001 and KT.00303.001. The unit is brand new and intended for owners whose original pack no longer holds a useful charge.

Direct-fit design with 500-cycle rating

The battery conforms to the original chassis dimensions and connector layout, so it slots into the compartment without adapters or cable rerouting. Cells are rated for up to 500 recharge cycles over the service life. Buyers who need a higher-capacity pack or a different voltage will not find those options here.

Low heat and silent operation

Li-ion chemistry runs cool during typical classroom or office workloads, and the pack has no moving parts so it adds no audible noise. Power draw follows the laptop’s own management, drawing only what the system requests. Users who require detailed thermal logs or active cooling data will not get that information from this product.
