Replacement battery for NOOK HD 7

This 4000mAh lithium-ion cell replaces the original Barnes & Noble BNA-B0002 pack in BNRV400 and BNTV400 tablets. It delivers 14.80Wh at 3.7 volts and fits the exact 127.90 x 68.75 x 3.70mm footprint. A fully decoded chip reports charge status to the tablet without extra configuration.

Capacity and daily headroom

The 4000mAh rating restores the runtime the tablet shipped with when new. Typical mixed use — reading, browsing, video — is covered for a full day; continuous high-brightness video will drain the pack in roughly half that time. Heavy multitasking or poor cellular signal pushes the limit sooner, so a mid-day top-up becomes practical.

Build, safety and installation

The pack carries ISO9001, RoHS and CE certification and includes over-charge, over-discharge, over-voltage and short-circuit protection circuits. Shock-absorbing foam in the retail box guards the cell during transit. Installation follows public video guides: open the rear case, disconnect the old connector, seat the new one and reassemble — no soldering required.

Questions about this item

Will the 127.90 x 68.75 x 3.70 mm battery fit the original compartment in my NOOK HD 7?

Yes, those dimensions match the factory battery pack for the BNRV400 and BNTV400 models.

How can I verify the 4000 mAh cell is working correctly after installation?

Run two or three full charge and discharge cycles; the decoded chip will then report capacity accurately to the tablet.

Does the package include tools or adhesive for the 130.0 g battery swap?

The box contains the battery with protective foam only; opening tools and adhesive strips must be sourced separately.
