Battery Care Tips
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
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 Book2 Pro 13 — 15.44V Li-Polymer Replacement Battery (AA-PBMN4MR)
This is a 15.44V, 4000mAh (61.76Wh) Li-Polymer battery for the Samsung Galaxy Book2 Pro 13 ultrabook. It replaces part number AA-PBMN4MR and fits the NP930XED series including KA1BE, KA1CL, KA1DE, and over 124 additional regional variants. Install this when the original cell no longer holds a usable charge or the system shuts down unexpectedly under load.
- NP930XED series fit: All NP930XED variants share the same 15.44V battery rail, connector pinout, and BMS handshake protocol. A single cell SKU covers the full regional lineup because Samsung locked the hardware spec across those production runs.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Galaxy Book2 Pro 13 unit. The BMS negotiated correctly, charge current ramped as expected, and the protection circuit tripped at the correct low-voltage threshold without spurious cutoffs.
- BIOS learn cycle after install: After fitting this cell, run the laptop down to hibernate cutoff on battery only — no AC — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on the NP930XED platform.
Galaxy Book2 Pro 13 shutting down at 20–30% after a battery swap
This is a voltage cliff problem, not a capacity fault. Under combined CPU and display load, the new cell hasn't yet been mapped by the fuel gauge IC, so the system reads available voltage inaccurately and triggers a protective shutdown before the cell is actually depleted. The BIOS battery learn cycle described in the care tip above resolves this in one to two full discharge-charge passes. After calibration, the fuel gauge tracks the new cell's discharge curve correctly and shutdowns at low-but-non-zero percentages stop.
BIOS reporting 0% or "unknown" battery immediately after installing a new cell
The EEPROM data written by the old cell persists in the system's battery management registers after a swap. The firmware briefly sees a mismatch between the stored cell profile and the new cell's reported parameters, which surfaces as 0% or an "unknown device" flag in both the BIOS and Windows battery status. This is not a fault with the replacement cell. Boot into the Samsung Battery Manager or Windows Settings > Power & Battery, confirm the cell is detected at any non-zero voltage, then complete one full discharge-to-hibernate and full recharge cycle to rewrite the register values to the new cell's baseline.

Frequently Asked Questions
The Galaxy Book2 Pro 13 shows the new battery as 0% or won't detect it at all in Windows — is the cell dead?
The EEPROM registers from the old cell are still sitting in the battery management firmware, causing a mismatch when Windows polls the new cell's identity data. Boot the laptop and check the BIOS battery screen first — if any non-zero voltage is reported there, the cell is functional. Run one full discharge to hibernate cutoff on battery only, then charge uninterrupted to 100%. That single cycle rewrites the stored parameters and clears the detection error.
Charge stops at 80% and won't go higher after installing the replacement AA-PBMN4MR — what's blocking it?
Samsung's BIOS includes a firmware-controlled charge limit that caps charging at 80% when "Maximum Battery Life" mode is active in Samsung Settings or the Windows battery charge threshold setting. This is a software cap, not a fault with the replacement cell. Open Samsung Settings > Battery and Power, then disable the charge limit or switch to "Maximum Charge" mode. The cell will then charge to 100% on the next charge cycle.
The Wh rating shown in Windows System Information reads differently from the 61.76Wh spec on the listing — why don't they match?
Windows reads the Wh figure from the EEPROM embedded in the battery's protection circuit, which stores the manufacturer's rated design capacity. If the old cell's EEPROM value is still cached in the OS power profile, or if the new cell's EEPROM was programmed to a slightly different nominal figure, the displayed number drifts from the actual electrochemical capacity. This is an EEPROM reporting difference, not a sign the cell is undersized. Complete the BIOS learn cycle — one full discharge to hibernate, one full charge to 100% — and Windows will update the reported figure against the new cell's actual measured output.
