Samsung P28 XVM 735 Replacement Battery 11.1V 6600mAh

Up to 17% off
New arrival
From $121.99 USD $146.99
Shipping calculated at checkout.
Fits Samsung P28 XVM 735 and replaces SSB-P28LS9, SSB-V20CLS/E, SSB-P28LS6/E battery packs.
11.1V and 6600mAh rating sustains the processor and display load without voltage sag under full CPU use.
Connector slides straight in with a single locking tab on the left side of the slot.
We bench-tested the cell against a P28 XVC 715 motherboard; BMS accepted the new pack on first insertion with no fault codes.
After installation, fully discharge to sleep mode then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears health warnings from the old cell's EEPROM data.

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 P28 XVM 735 / P28 XVC 715 — 11.1V Li-ion Replacement Battery (SSB-P28LS9)

This is an 11.1V, 6600mAh (73.26Wh) lithium-ion battery for the Samsung P28 series laptops, including the XVM 735, XVC 715, P28-GCXVM350, and SP28 JUMP among others. It replaces OEM part numbers SSB-P28LS9, SSB-V20CLS/E, SSB-P28LS6/E, SSB-P28LS6, and SSB-V20KLS. Fits directly into the original battery bay with no modifications.

  • P28 series compatibility: These models share the same 11.1V three-cell voltage rail, physical connector pinout, and BMS handshake protocol — which is why one cell covers the full P28 lineup despite the varied model suffixes.
  • Bench tested on actual hardware: We ran this cell through full charge and load cycles on P28-series hardware. The BMS held voltage within spec across the discharge curve, and the protection circuit tripped correctly at low-cell threshold before reaching damaging depth.
  • First-cycle reset after install: After fitting this cell, run a full discharge to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting battery health as poor immediately after replacement

The Samsung P28's BIOS reads health data from EEPROM registers on the battery's fuel gauge IC — not from live voltage. When a new cell is installed, those registers still carry the degradation profile of the old pack. The BIOS sees this stale data and flags health as poor or unknown before any real measurement occurs. Running one full discharge-to-cutoff cycle followed by an uninterrupted charge to 100% rewrites the fuel gauge's learned capacity registers. After one or two calibration cycles, the health reading normalises to reflect the new cell's actual condition.

Laptop shuts down at 20–30% charge shown on meter

This happens when the fuel gauge IC hasn't yet calibrated against the new cell's discharge curve. The gauge underestimates remaining capacity and reports a higher percentage than the cell can actually sustain under combined CPU and display load. When the cell voltage drops below the BMS cutoff threshold — typically around 9.0–9.3V for an 11.1V three-cell pack — the system shuts down even though the OS still shows charge remaining. Run two full discharge-to-hibernate cycles charged back to 100% each time to let the fuel gauge IC re-anchor its curve to the new cell's actual voltage profile.

Frequently Asked Questions

My Samsung P28 shows the battery as "unknown" or 0% right after I put in the new cell — is the battery dead?

The battery is not dead. The P28's BIOS reads health and charge state from EEPROM registers on the old pack, and those registers don't exist yet on the new cell until calibration runs. The system reports unknown or 0% because it has no learned data to reference. Plug in the AC adapter, let the cell charge uninterrupted to 100%, then discharge fully to hibernate cutoff — after that cycle, the gauge IC writes its baseline and the reading corrects.

The laptop cuts off suddenly at around 25% — why is it shutting down with charge still showing?

The fuel gauge IC hasn't calibrated against the new cell yet, so the percentage shown doesn't match the actual cell voltage. Under full CPU and display load, the cell voltage drops faster than the uncalibrated gauge expects, and the BMS cuts power when voltage falls below roughly 9.0V — even though the OS still displays 25% remaining. Run two full discharge-to-hibernate cycles with a full charge to 100% between each one. After that, the gauge re-anchors its curve to the new cell and the shutoff point moves back to near zero.

System info shows the wrong Wh rating for the battery — the P28 is listing a lower number than the 73.26Wh on the spec sheet. What's happening?

The Wh figure shown in Windows or BIOS is pulled from the EEPROM data embedded in the fuel gauge IC, which stores the rated value from the original OEM cell — not a live measurement of the new pack. Until at least one full discharge-and-recharge cycle runs, the IC reports the old cell's rated Wh rather than recalculating from the new cell's actual chemistry. Complete one full discharge to hibernate cutoff followed by a full uninterrupted charge to 100%, and the system will recalculate the Wh figure from the updated capacity registers.
