Direct replacement for Acer Chromebook 11

The NShi AC15A3J is a three-cell lithium-ion battery rated at 10.8 V and 36 Wh with a capacity of 3490 mAh. It matches OEM part numbers AC15A3J, KT.00303.017 and KT.00305.004 and fits the Chromebook 11 C735, CB3-131, C738T, CB5-132T and R11 series. Owners of those models can restore original runtime without modification.

Thermals noise and power in daily use

The pack uses standard lithium-ion chemistry that runs cool during typical classroom or office workloads and produces no audible noise because it has no moving parts. Self-discharge is kept low by the onboard protection circuit, so the battery holds charge well between lessons or shifts. No extra power draw is introduced beyond the laptop’s own charging profile.

Build quality and connector implications

Each unit is tested for correct voltage, stable current and circuit protection before shipping and carries CE, FCC and RoHS safety certifications. The black casing aligns with the original battery bay, so the laptop sits flat and the latch engages normally. Buyers who need a higher-capacity pack or a different voltage for another device line will not be served by this model.

Questions about this item

How do I install this AC15A3J battery in my Acer Chromebook C735 and what step is often missed?

Power off the Chromebook, remove the bottom case screws, disconnect the old battery connector, fit the new 3-cell pack, reconnect the cable, then replace the case and screws; the step often missed is reconnecting the battery cable before closing the case.

What maintenance or replacement will this 10.8V 36Wh pack need later?

The lithium-ion cells gradually lose capacity; when run time drops below your needs, replace the pack with another AC15A3J or KT.00303.017 unit.

What limit appears first during sustained use of this 3490mAh battery?

The 36Wh capacity determines how long the Chromebook runs before the pack must be recharged.
