Shipping calculated at checkout.
Fits Barnes & Noble Nook 10.1 tablets, replaces OEM part GSP30134138.
3.8V, 6300mAh lithium-polymer cell restores full charge capacity to the 10.1-inch display.
Connector slides straight into the battery slot with the locking tab aligned left.
We bench-tested the pack on a Nook 10.1 running full WiFi load — BMS accepted the charge handshake on cycle one with no fault codes.
After installation, run one full discharge to automatic shutoff then charge uninterrupted to 100% — this resets the fuel gauge IC calibration against the new cell.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Barnes & Noble Nook 10.1 (BNTV650) — 3.8V Li-Polymer Replacement Battery (GSP30134138)

This is a 3.8V, 6300mAh lithium-polymer replacement battery for the Barnes & Noble Nook 10.1 tablet (model BNTV650). It replaces OEM part GSP30134138 and fits the original battery bay without modification. Dimensions are 130.10 × 107.40 × 3.30mm — verify your original cell matches before installation.

  • Nook 10.1 and BNTV650 compatibility: Both model names refer to the same hardware revision. The BNTV650 shares an identical connector pinout, voltage rail, and BMS handshake requirement, so one cell covers both listings without any adapter or wiring change.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on a BNTV650 unit. The BMS accepted the handshake on first connection, the charge IC ramped normally to 4.2V, and no protection trips were recorded under display-plus-WiFi load.
  • Post-installation calibration on the Nook 10.1: After fitting the new cell, run one full discharge to automatic shutoff, then charge uninterrupted to 100% without interrupting the session. This resets the fuel gauge IC calibration against the new cell — skipping it causes the percentage readout to drift or report inaccurately from day one.

Why the Nook 10.1 shuts down between 15–25% after a battery swap

The fuel gauge IC on the BNTV650 maps voltage curves from the old, degraded cell. When a fresh cell is installed, the IC's internal charge map no longer matches the new cell's actual voltage profile. Under combined display-plus-WiFi load, the voltage drop looks steeper than the IC expects, so it triggers an emergency cutoff well before the cell is actually depleted. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% rewrites the calibration data and clears the premature cutoff.

Fast charging not available on the Nook 10.1 after replacement

The BNTV650 charge IC uses a handshake with the charger during the first accepted charge cycle to confirm cell parameters before enabling higher current draw. If the device is powered on, restarted, or disconnected during that first charge, the negotiation resets and fast charge stays locked. Connect the tablet to its original charger, leave it powered off, and allow the full charge cycle to complete without interruption — fast charge should be available from the next session onward.

Frequently Asked Questions

My Nook 10.1 says 80% but drops to zero and shuts off — is the new battery faulty?

The battery is almost certainly fine. The fuel gauge IC calibrated itself to the old, worn cell and its voltage map no longer matches the new one. Drain the tablet fully until it shuts itself off, then charge it uninterrupted to 100% with the screen off. That single cycle resets the IC calibration and eliminates the false readout.

The Nook 10.1 feels warm near the charging port while charging the new battery — should I stop?

Some warmth near the charge IC is normal on the first few cycles after a swap. The charge IC is running a fresh conditioning pass on the new cell and operating at slightly higher current than steady-state. If the back of the tablet gets hot enough to be uncomfortable to hold, disconnect and check that the charger output matches the original spec — 5V/2A for the BNTV650.

The battery percentage on my Nook 10.1 drops faster from 100% than it did with the original battery — why?

This is fuel gauge drift, not cell capacity loss. The IC is still using the old discharge curve and over-reports consumption in the upper charge range immediately after a swap. Run one complete discharge to automatic shutoff followed by a full uninterrupted charge to 100%. After that single calibration cycle, the percentage steps should even out and match actual remaining capacity.
