Acer Aspire E3-112 ES1-511 Laptop Battery

Acer AC14B8K / Replacement Battery for Aspire E3-112 & ES1-511 (15.2 V 48 Wh)

If your Acer Aspire E3-112 or ES1-511 laptop is showing diminished runtime, abrupt shutdowns, or battery wear-out signs, upgrading to the Acer AC14B8K replacement battery is a wise investment. Engineered to match the original manufacturer’s specifications, this 4-cell lithium-ion battery delivers 15.2 V nominal voltage and a healthy 48 Wh (approximately 3,220 mAh) capacity, restoring the reliable portable power your system needs.

This battery is designed for seamless compatibility and installation: it fits directly into the laptop’s battery compartment without modification and includes built-in safety protections typical of quality lithium-ion packs (over-charge, over-discharge, short-circuit prevention). Whether you use your laptop for study, work, or light entertainment, you’ll appreciate the improved stability and runtime compared to a worn-out original pack.

Why This Battery Matters:

Over time, laptop batteries lose capacity. A fresh battery like the Acer AC14B8K allows your machine to run untethered again, helps prevent unexpected shutdowns, and gives you the freedom to use your laptop away from the wall outlet for longer. With genuine replacement cells and proper voltage matching, you reduce the risk of performance issues, charging errors or system warnings related to battery health.
