Cameron Sino BNA-B0002 4000mAh 3.7V Battery for NOOK HD 7

Replacement Battery for NOOK HD 7

The Cameron Sino BNA-B0002 is a lithium polymer replacement battery built for the NOOK HD 7, BNRV400 and BNTV400 tablets. It delivers a 4000mAh capacity at 3.7V and matches the original dimensions of 127.90 x 68.75 x 3.70mm. A fully decoded chip ensures the tablet recognises the cell and reports charge levels correctly. The pack weighs 130.0g and meets ISO9001, RoHS and CE certification standards.

Suitable for owners restoring a compatible NOOK HD 7

This unit suits owners of the listed NOOK HD 7, BNRV400 or BNTV400 models who need a direct replacement with the original connector and form factor. It is not for users whose tablet uses a different part number or physical layout, nor for anyone requiring a higher capacity cell than the specified 4000mAh. Buyers should verify the exact model and part number before purchase to avoid fitment issues.

4000mAh capacity with standard voltage headroom

The 4000mAh / 14.80Wh rating provides a like-for-like energy reserve for typical reading and browsing sessions on the target tablets. It comfortably handles normal daily cycles and includes overcharge, over-discharge, over-voltage and short-circuit protection circuits. Runtime will diminish under continuous high-load use or after many charge cycles, at which point the cell reaches its service limit.
