Replacement Battery for EeeBook E402 E502

This NShi lithium-polymer battery replaces part numbers B21N1505 and 0B200-01400200M in compatible Asus EeeBook E402 and E502 series notebooks. It delivers 7.6V and a rated capacity of 32Wh or 4240mAh. The unit is supplied new and ready to install with the original charger.

Fits Specific E402 and E502 Sub-Models Only

The part suits owners of listed E402MA E402SA E402NA and E502SA variants who have confirmed their original battery matches the product images. It will not work for users whose EeeBook uses the alternate B21N1505 design or a different part number entirely. Buyers needing a universal fit should look elsewhere.

B21N1505 exists in two distinct layouts that are not interchangeable despite the identical model code. Verifying the exact shape and connector against the supplied photographs is the single step that decides whether this battery will install correctly.
