Replacement battery for Acer Aspire E15 series

This 14.8V 2600mAh lithium-ion pack replaces the original AS16A5K, AS16A7K and AS16A8K batteries used across numerous Acer Aspire E15 and F5 models. It is built for owners whose factory cell no longer holds a useful charge and who want a direct, plug-in swap without adapter cables or firmware tricks.

Four-cell black pack with included screwdrivers

The unit ships as a single 4-cell block in black, matching the form factor of the 4ICR19/66 reference. Grade A cells and built-in circuit protection support up to 500 recharge cycles while guarding against over-charge and short-circuit. Free screwdrivers in the box let you open the service hatch and secure the battery without hunting for tools.

Restores runtime on ageing E5-575.

If your laptop still meets your performance needs but dies away from a wall socket, this battery returns it to mobile use. The upgrade is worth it when the original pack delivers only minutes of work or refuses to charge, and the chassis itself remains structurally sound. Buyers needing higher capacity than 2600mAh or a different voltage should look elsewhere.

Questions about this item

Does the 14.8V lithium-ion pack charge through the laptop's standard power connector?

Yes, the 14.8V 2600mAh battery uses the same connector as the original Acer Aspire E15 E5-575 series packs and plugs directly into the internal battery header.

What physical space does the 4-cell black pack occupy in the chassis?

The 4-cell design matches the factory footprint for Acer Aspire E5-475 E5-523 E5-553 E5-575 E5-576 F5-573 and F5-771 series, so it seats in the existing battery bay without adapters.

Which step do installers most often skip when fitting the AS16A5K?

After placing the battery, many forget to re-engage the locking latch; the included screwdrivers help remove the bottom cover, but the latch must click to secure the pack and complete the circuit.
