Direct replacement battery

The POWER-FENG AC14A8L is a 52.5Wh 11.4V lithium-polymer battery built to replace the original pack in compatible Acer laptops. It fits models including the Aspire VN7-571, VN7-571G, VN7-572, VN7-591, VN7-591G, VN7-592 and VN7-791G. The black unit ships brand new and matches the OEM form factor for a straight swap.

Capacity and voltage define runtime

A 52.5Wh rating at 11.4V sets the practical energy ceiling for any single charge. Lithium-polymer chemistry delivers stable voltage until the pack is nearly empty, but total runtime still depends on the laptop’s power draw under load. The 4605mAh cell count is fixed, so heavier workloads will drain the battery proportionally faster.

Match the AC14A8L part number

The AC14A8L code is the single specification that confirms fit across the listed Aspire VN7 and VX5 series as well as the Shadow Knight 2 and 3 chassis. Cross-reference this exact number against the label on your original battery before ordering; a different part number indicates a different pinout or physical profile that will not install.

Questions about this item

Which capacity version of the AC14A8L battery should I choose for my Acer Aspire VN7-571?

This AC14A8L battery is offered in a single 52.5 Wh / 4605 mAh capacity; there are no alternative capacity versions listed for the compatible Acer Aspire models.

What does the 11.4 V rating mean once the battery is installed in my laptop?

The 11.4 V rating matches the original design voltage for the listed Acer Aspire VN7 series, so the laptop's power management will recognise it correctly and report charge levels normally.

What interface does this battery use and what does it limit in practice?

The battery connects via the proprietary multi-pin connector used by the Acer Aspire VN7, VX5 and Shadow Knight chassis; it limits replacement to models that share that exact connector and 11.4 V rail.
