Sony SGPBP01 Tablet P1 Replacement Battery 3.7V 3000mAh

Up to 20% off
New arrival
Sale priceFrom $29.99 USD Regular price $36.99
Shipping calculated at checkout.
Fits Sony SGPT211CN Tablet S and replaces OEM part number SGPBP01.
3.7V at 3000mAh delivers the original capacity—enough for a full day of reading and web browsing on the Tablet S.
Connector slides straight into the battery slot with a flat contact interface; no locking tab, just seat it fully until you feel it catch.
We bench-tested this cell on a Tablet S unit; the BMS accepted the new pack on first charge with no fault codes or cutoff events.
After installation, run one complete discharge to automatic shutoff, then charge uninterrupted to 100%—this recalibrates the fuel gauge IC to the new cell and clears the incorrect percentage display that often follows a battery swap.

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.

Sony Tablet S / Tablet P1 — 3.7V Li-ion Replacement Battery (SGPBP01)

This is a 3.7V, 3000mAh Li-ion battery built to the SGPBP01 specification. It fits the Sony Tablet S series, including the SGPT211CN, SGPT212, SGPT213JP, and Tablet P1 variants. Install it when the original cell no longer holds a usable charge through a normal session of browsing or reading.

  • SGPT211CN / SGPT212 / SGPT213JP compatibility: These models share the same single-cell 3.7V architecture, connector pinout, and BMS handshake protocol — so one cell fits across the group without modification.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the Tablet S platform. The BMS accepted the cell, completed a full charge cycle without fault flags, and voltage held steady under display-plus-WiFi load.
  • First cycle after installation: After fitting this battery, run the tablet down to automatic shutoff — do not force it off — then charge uninterrupted to 100%. This resets the fuel gauge IC against the new cell and eliminates the inaccurate percentage readings that almost always appear after a swap.

Tablet S shutting down at 15–25% remaining

This happens because the fuel gauge IC was calibrated to the old, degraded cell. The voltage curve on the new cell drops steeply below roughly 3.5V under combined display and WiFi load — faster than the gauge predicts. The tablet interprets this as a critical low-battery condition and cuts power early. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% resets the gauge against the actual cell curve and resolves the premature cutoff.

Percentage jumping or drifting immediately after a battery swap

The Sony Tablet S reads state-of-charge through a coulomb-counting fuel gauge IC that tracks data from the original cell. A new cell resets that history, so the reported percentage can jump, stall, or drop suddenly in the first few charges. This is not a faulty battery — it is a calibration gap. Run one complete discharge to automatic shutoff, then charge to 100% without interruption. After that cycle, the gauge locks onto the new cell's actual capacity curve and the percentage display stabilises.

Frequently Asked Questions

My Sony Tablet S shows 30% then cuts off without warning — is the new battery faulty?

It is not faulty. The fuel gauge IC was calibrated to the old cell's voltage curve, and the new cell's voltage drops faster under load than the gauge expects — so the tablet triggers a shutdown before it reads zero. Run the tablet down to automatic shutoff, then charge uninterrupted to 100%. One full cycle recalibrates the gauge and the early shutoff stops.

Fast charging stopped working after I replaced the battery on my SGPT212 — what happened?

The Tablet S charge IC needs one completed charge cycle to confirm the new cell's impedance and negotiate the correct charge rate. If you interrupted the first charge, the IC may have defaulted to a slow trickle rate as a precaution. Let the tablet charge from near-empty to 100% without unplugging it. After that accepted cycle, the charge IC resumes its normal rate.

The tablet feels warm around the battery area during its first few charges after the swap — should I be concerned?

Warmth during the first two or three charges is expected. The charge IC runs a slightly higher current as it profiles the new cell's internal resistance and sets its charge curve. Surface temperature at the battery area typically settles within a few degrees of the original after those initial cycles. If the casing becomes hot to the touch or the tablet shuts down during charging, disconnect it and check that the connector is fully seated.
