Replacement battery for Asus E402NA

This 32Wh lithium-polymer pack replaces part number B21N1505 in Asus E402N and E402NA notebooks. It delivers 7.6V and 4240mAh from a black casing. The unit ships new and ready for immediate installation.

Straightforward swap with basic tools

The battery sits inside the bottom case and connects through a keyed cable. Most owners remove a few screws, unplug the old pack, and seat the new one in minutes. Forcing the connector or skipping the screw sequence can bend pins or leave the pack loose.

Confirm exact model and connector match

Verify the laptop shows E402N or E402NA on its service tag before ordering. Cross-check the original battery label for B21N1505 and the 7.6V rating. A different sub-model may use a similar shape but a different pin-out or voltage.
