ALSEYE s70-NXM1B2200Z 2 in 1 accessory 6-cell 5200mAh 11.1V Li-ion

6-cell 5200 mAh Li-ion replacement battery

This 11.1 V lithium-ion pack replaces the original battery in compatible ASUS A52, K52, X52 and X62 series laptops. It supplies 5200 mAh capacity across six cells and includes overcurrent, overcharge, overdischarge and temperature protection circuits. The unit is new from the manufacturer and rated for up to 500 recharge cycles. It suits owners of the listed models who need a direct drop-in replacement.

Sustained output with protection circuits

The pack delivers steady 11.1 V power through its six cells while the built-in protection board guards against overcurrent, overcharge, overdischarge, overheating and short circuits. These safeguards maintain consistent voltage during long work sessions and prevent cell damage from deep discharge or excessive heat. Rated cycle life reaches 500 full charges before capacity drops below useful levels. No active cooling is required; the laptop's own thermal management handles dissipation.

Direct fit for listed part numbers

Installation follows the standard battery-bay release latch on each supported chassis; no tools or firmware updates are needed. The battery ships at a partial charge so calibrating with a full charge-discharge cycle improves reported capacity accuracy. Common issues arise only when the laptop model or part number is not on the approved compatibility list, leading to physical misalignment or unrecognised capacity. Verifying the exact part number against the 42, 52, 62, 67, 70, 90, 681 and 1000 series codes avoids returns.
