Compatible NOOK Classic replacement

The Estry BNRV100 is a lithium rechargeable battery built to match the original specifications for Barnes & Noble NOOK Classic and nook devices. It fits models BNRV100, BNRZ100 and 005, and replaces part numbers BNRB454261, 9BS11GTFF10B3, BNRB1530, 9875521 and BNRZ1000. Buyers should verify the exact model and part number before ordering. This unit is not for owners of other e-reader brands or newer NOOK generations.

Lithium cell voltage and capacity limits

The cell operates at 3.7V with a rated capacity of 1250mAh, delivering 4.63Wh of energy. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits. The lithium chemistry defines the practical voltage window and cycle life; no other interface or protocol is involved. Users needing a different voltage or a higher milliampere-hour rating must look elsewhere.

Physical size and energy headroom

The pack measures 65.8 x 53.7 x 4.8mm and weighs 52.0g, matching the original form factor for a direct swap. At 4.63Wh it provides the same runtime as the factory cell for typical reading sessions. Heavier workloads such as continuous Wi-Fi use or maximum screen brightness will deplete the charge faster, and the fixed capacity cannot be expanded.
