Replacement Battery for Acer Aspire 1 and 3

This 7.7 V lithium-ion pack delivers 37 Wh and 4810 mAh across four cells. It matches part numbers AP16M5J, KT.00205.004, KT00205004, KT.00205.005, KT00205005 and 2ICP4/80/104. The unit is supplied new and ready for installation in compatible Aspire 1 A114-31, A114-32 and Aspire 3 A314, A315 series notebooks.

Thermals and Power in Normal Use

Li-ion chemistry keeps self-discharge low and maintains stable voltage during typical office workloads. The 37 Wh capacity supports several hours of unplugged use without generating excess heat. No active cooling is required, so the battery adds no audible noise to the system.

What the Bundled Accessories Change

The package contains only the battery itself; no tools, screws or software are included. Installation relies on the laptop's existing latch or screw mechanism. Users must verify their exact model against the listed part numbers before fitting to avoid mismatched connectors or form factors.

Questions about this item

How do I install the AP16M5J battery in my Acer Aspire A515-51 and what step is often missed?

Power off the laptop, unplug the AC adapter, remove the bottom case screws, disconnect the old pack from the motherboard connector, fit the new 7.7V 4-cell unit, reconnect the cable firmly, then reassemble; the step most people skip is reconnecting the battery cable before closing the case.

What maintenance or replacement will the AP16M5J need over time?

The 37Wh lithium-ion pack loses capacity with every charge cycle; when run time drops below your needs, replace it with another AP16M5J or compatible KT.00205.004 unit.

What limit appears first during sustained use of the AP16M5J?

The 4810mAh capacity determines how long the laptop runs before the voltage drops to the 7.7V cutoff, so heavy loads hit the runtime limit first.
