Samsung Galaxy Note 8 EB-BN950ABE Replacement Battery 3.85V 3300mAh

Up to 20% off
New arrival
From $25.99 USD $31.99
Shipping calculated at checkout.
Fits Samsung Galaxy Note 8 smartphones and replaces OEM battery EB-BN950ABE.
3.85V 3300mAh Li-Polymer cell matches original capacity for standard daily use cycles.
Connector seats flush into the Note 8 battery slot with no tab obstruction or alignment issues.
We bench-tested this cell against the fuel gauge IC on SM-N9500 hardware — BMS accepted the charge handshake without fault codes across three full cycles.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the coulomb counter recalibrates against the new cell's discharge curve before high-current charging resumes.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

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.

Samsung Galaxy Note 8 — 3.85V Li-Polymer Replacement Battery (EB-BN950ABE)

This 3.85V Li-Polymer cell replaces the original EB-BN950ABE battery in the Samsung Galaxy Note 8 and Galaxy Note 8 Duos. Capacity is 3300mAh (12.71Wh), matching the factory specification. It fits SM-N9500 and the full Note 8 variant lineup including TD-LTE Duos models.

  • Note 8 variant coverage: The SM-N9500, Duos, and TD-LTE Duos variants all share the same battery footprint, connector pinout, and BMS handshake protocol — one cell covers every unit in the Note 8 generation.
  • Bench tested on actual hardware: We ran this cell on a Note 8 bench unit and confirmed the BMS accepted charge negotiation without fault flags, and that the charge IC cycled through CC/CV phases cleanly from 0% to full.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging pushes into an uncalibrated state.

Sudden shutdown at 20–30% on the replacement cell

This is a voltage cliff issue. Under high-draw conditions — active LTE modem, screen at full brightness, or GPS — the cell voltage drops faster than the fuel gauge IC predicts based on the old discharge curve. The phone's low-voltage cutoff triggers before the displayed percentage reaches zero. One full discharge-charge cycle without fast charging resets the coulomb counter and tightens the IC's voltage-to-percentage mapping. After calibration, shutdowns below 20% stop occurring.

Phone not powering on after the replacement battery sat in storage

Li-Polymer cells shipped or stored for extended periods can self-discharge below 2.5V per cell. At that level, the BMS enters lockout mode and blocks current flow to protect the cell from damage. The phone will show no sign of life — no charge animation, no vibration. Connect to a wall charger at 5V/1A (not a fast charger) and leave it undisturbed for 20–30 minutes. Once voltage climbs above the BMS recovery threshold, the charge animation will appear and normal charging resumes.

Frequently Asked Questions

The Note 8 shows 25% battery and shuts off without any warning — is this the new cell or something else?

This is a fuel gauge IC mismatch, not a faulty cell. The coulomb counter inside the Note 8 was calibrated to the discharge curve of the original, degraded cell — it no longer maps accurately to the new cell's voltage behaviour. Under modem or screen load, actual cell voltage drops below the shutdown threshold before the displayed percentage catches up. Run one full discharge down to auto-shutdown, then charge uninterrupted to 100% with fast charging turned off — that single cycle recalibrates the IC.

Fast charging stopped working after I swapped the battery — the phone just trickle charges now.

Samsung's Adaptive Fast Charging protocol requires the charge IC to negotiate with the BMS on the first cycle. On a brand-new cell, the BMS sometimes rejects the high-current handshake until it has completed one standard charge cycle. Charge the phone once at normal speed from under 20% to 100%, then plug in again — the fast charge icon should reappear. If it does not, check that you are using a Samsung-certified charger outputting at least 9V/1.67A, as third-party adapters often fail the protocol negotiation entirely.

The Note 8 feels warm near the back panel while charging with the new battery — is that normal?

A new Li-Polymer cell has slightly higher internal impedance than a well-cycled cell, so the charge IC dissipates a little more heat during the initial CC phase. This is normal for the first two to three charge cycles and fades as the cell conditions. If the back panel becomes hot to the touch — above what you would call warm — remove the charger and let the phone cool before continuing. After three full cycles, internal impedance drops and charging temperature returns to the same level you would expect from the original battery.
