Battery AVACOM NOAS-K52S-N22 for ASUS A42 A52 K52 X52, Li-Ion 4400 mAh, black
AVACOM NOAS-K52S-N22 is a replacement Lithium‑Ion battery designed for select ASUS laptop models including A42, A52, K52 and X52 series. With a nominal capacity of 4400 mAh and a black finish, this battery is built to meet OEM-style specifications for safe operation and to restore mobile runtime when the original battery no longer holds sufficient charge. It is intended as a direct swap for compatible notebooks, offering a balance of capacity and physical compatibility for everyday use.
The Lithium‑Ion construction provides stable energy density and predictable discharge characteristics while keeping weight and size appropriate for laptop use. A rated capacity of 4400 mAh extends operating time compared with deeply worn cells and helps reduce the need for frequent recharging during typical office, study or light multimedia sessions. The black housing matches the aesthetic of many ASUS laptops and the product is manufactured to follow safety and performance guidelines common for replacement notebook batteries.
Power down the laptop and disconnect it from the AC adapter before attempting battery replacement. Remove the existing battery following the notebook manufacturer's instructions, then insert the replacement pack ensuring the contacts align and the latch secures the battery. After installation, connect the AC adapter and allow the system to detect the new battery; an initial full charge is recommended to calibrate the battery meter. Use standard operating procedures for charging and discharging as described by the laptop maker.
Use the battery within the laptop models listed and avoid exposing the pack to extreme temperatures, moisture, or mechanical shock. For prolonged storage, keep the battery at approximately 40–60% charge in a cool, dry place. If irregular behaviour is observed (excessive heat, swelling, or rapid capacity loss), discontinue use and follow local regulations for battery disposal or recycling.
