Replacement Battery for Acer Aspire 5

The NShi AP18C4K is a 11.4V 48Whr lithium-ion battery built for Acer Aspire 5 models including A514-52, A515-43 and A515-54 series. It replaces OEM part numbers AP18C4K, KT00304012 and KT.00304.012. Owners of those laptops can swap the old pack without tools beyond a screwdriver.

Three-Cell Design and Fit

The three-cell brick slides into the existing battery bay and connects to the stock motherboard header, so no adapter cables or BIOS updates are required. It frees the user from a tethered power brick and restores full portability for daily commuting or classroom work.

48Whr Capacity and Limits

At 4200mAh the pack delivers typical light-office runtime of several hours before needing a recharge. Heavy workloads such as video rendering or gaming will drain it faster, and the fixed three-cell layout means no internal expansion is possible. Users needing all-day autonomy must carry a charger or a second battery.

Questions about this item

How long does the 48 Whr capacity last under sustained load?

The 48 Whr rating means the pack can deliver 48 watts for one hour; actual run-time depends on the laptop's power draw, which varies by model and workload.

Does the battery generate noticeable heat or noise during all-day use?

Lithium-ion cells produce no noise and minimal heat under normal operation; the laptop's own cooling system manages any warmth from discharge.

Which Acer Aspire models must I already own for this AP18C4K to fit?

It fits Aspire 5 A514-52, A515-43 and A515-54 series including sub-models such as A514-52G, A515-43G and A515-54G variants listed in the compatibility data.
