Shipping calculated at checkout.
Fits Samsung R50-V01 and R55 series laptops; replaces OEM part AA-PB0NC6B and AA-PB1NC6B variants.
11.1V and 4400mAh capacity delivers 48.84Wh — matched to Samsung R-series original pack specs for full runtime restoration.
Connector seats flush into the battery bay slot with a positive locking tab that clicks into the retention frame when seated fully.
We bench-tested this cell on an R50-V01 load profile; the BMS accepted the initial charge cycle without cutoff or voltage drift anomalies.
After installation, discharge fully to system hibernation-cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears false health warnings.

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 R50-V01 / M55 / R55 Series — 11.1V Li-ion Replacement Battery (AA-PB0NC6B)

This is an 11.1V, 4400mAh (48.84Wh) Li-ion battery for the Samsung R50-V01 and related R/M-series notebooks. It fits the OEM connector and BMS handshake on the R50-V01, M55 XEP 2500, R55-T5200 Piper, R50-CV05, and over 100 additional Samsung notebook variants sharing the AA-PB0NC6B platform. Drop the OEM part number into your system specs tab before ordering to confirm the match.

  • R/M-series platform compatibility: These models share a common 11.1V three-cell Li-ion architecture with the same connector pinout and BMS communication protocol. Samsung kept this battery standard across a wide production run, so one cell replaces a broad range of SKUs without firmware or connector changes.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on R-series hardware and confirmed the BMS handshake initialised correctly, charge termination triggered at full capacity, and the protection circuit tripped cleanly on simulated over-discharge.
  • First-cycle calibration on Samsung notebooks: After installing, run the laptop down to hibernate cutoff on battery alone — no AC during the discharge. Then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to re-baseline against the new cell and clears the inaccurate health warning that typically appears after every cell swap.

Why Samsung R-series BIOS flags replacement cells as poor health

Samsung's BIOS reads EEPROM data written by the original factory cell. When a new cell is installed, that EEPROM profile no longer matches the live chemistry data the BMS is reporting, so the BIOS health meter reads low or unknown. This is a calibration state, not a fault. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% lets the BIOS rewrite its learned capacity baseline against the new cell. After two or three of these cycles the health indicator normalises.

Laptop shuts down at 20–30% shown on the gauge

This happens when the fuel gauge IC still holds calibration data from the old, degraded cell. Under full CPU and display load, the new cell's voltage curve doesn't match the outdated lookup table, so the gauge reads 20–30% while the real state of charge is far lower — and the system shuts down to protect the cell. The fix is a full recalibration: discharge fully to hibernate cutoff, then charge uninterrupted to 100%, and repeat once more. After two complete cycles the fuel gauge IC recalculates against the new cell's actual voltage curve and the shutdowns stop.

Frequently Asked Questions

My Samsung R50 shows the new battery as "0% available (plugged in, charging)" and it never moves — what's wrong?

The BIOS is still reading EEPROM state data from the old cell and hasn't accepted the new one yet. Disconnect AC, let the laptop run down to hibernate cutoff on battery alone, then plug in and charge uninterrupted to 100% without using the machine. This triggers the battery learn cycle and forces the BIOS to rewrite its baseline against the new cell. After one full cycle the charge percentage should display and update correctly.

Windows is showing this battery as 48Wh but the Samsung battery info utility says something different — which is right?

The Samsung utility pulls its Wh figure from the EEPROM profile written by the original factory cell, which reflects that cell's rated chemistry, not the installed replacement. Windows reads the live BMS data from the actual cell, so the 48.84Wh figure Windows reports is the accurate one. The discrepancy disappears after the BIOS battery learn cycle rewrites the stored profile. Run one full discharge-to-hibernate then a complete uninterrupted charge and the utility figure will align.

The charge stops climbing at around 80% and just sits there — is the new cell faulty?

Not necessarily — Samsung notebooks include a BIOS-controlled charge limit that activates when the battery health flag hasn't been cleared after a cell swap. The BMS receives a charge-ceiling instruction from the BIOS before the learn cycle runs. Discharge the laptop fully to hibernate cutoff on battery, then charge uninterrupted to 100% with no use during the charge. This resets the BIOS charge limit logic; on the next charge cycle the cell should reach 100%.
