Compatible replacement battery for Asus VivoBook

The POWER-FENG C21N1521 is a 38Wh lithium-polymer battery rated at 7.6V and 5000mAh. It replaces the original C21N1521 part for Asus E200H and E200HA models. The unit ships new in black and restores mobile power to supported ultraportable laptops.

Simple internal swap with connector alignment care

Installation requires opening the laptop chassis and disconnecting the old pack before fitting the new one. The main risk is misaligning the multi-pin connector or trapping the ribbon cable during reassembly. Take photos of the original cable routing and screw positions before starting work.

Verify exact model code and original part number

Confirm the laptop bottom case lists E200HA-1A, E200HA-1B or E200HA-1E and that the existing battery carries the C21N1521 label. Different regional variants of the E200H series may use a different pack, so matching the part number is essential before ordering.
