Fits Lenovo Tab M10 Plus TB-X606F; replaces OEM part L19D1P32.
3.85V, 4800mAh Li-Polymer cell restores full charge cycles to the tablet.
Connector seats flush into the internal battery slot with no locking tab.
We ran a full discharge-to-shutdown cycle on the TB-X606F; BMS accepted charge without fault codes.
After installation, run one full discharge to automatic shutoff then charge uninterrupted to 100% — this resets the fuel gauge IC calibration against the new cell and resolves inaccurate percentage display.

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.

Lenovo Tab M10 Plus TB-X606F — 3.85V Li-Polymer Replacement Battery (L19D1P32)

This is a 3.85V, 4800mAh Li-Polymer battery for the Lenovo Tab M10 Plus (TB-X606F). It replaces OEM part number L19D1P32 and restores charging capacity to the 10-inch Android tablet. Fit the battery when the original cell no longer holds a usable charge across a full day of media or productivity use.

  • TB-X606F platform fit: The Tab M10 Plus TB-X606F uses a flat Li-Polymer pouch cell matched to the charge IC on the board. This L19D1P32 replacement carries the same 3.85V nominal voltage and 116.10 x 97.50 x 2.60mm cell dimensions, so the connector seats correctly and the charge controller accepts the cell without fault codes.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on TB-X606F hardware. The BMS accepted the new cell without triggering an overcurrent trip, and the charge IC cycled through constant-current and constant-voltage phases cleanly. Capacity read-back at the OS level matched rated capacity after one full calibration cycle.
  • Fuel gauge reset after installation: After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without using the device. This forces the fuel gauge IC to recalibrate against the new cell's actual voltage curve — it clears the inaccurate percentage readings that appear immediately after a swap.

Tab M10 Plus shutting down at 15–25% remaining after battery replacement

The TB-X606F pulls simultaneous load from the display backlight, WiFi radio, and processor when streaming or browsing. Under that combined draw, cell voltage drops faster than it does under a light load. The fuel gauge IC, still calibrated to the old cell's discharge curve, misreads the voltage cliff and signals the OS to shut down — even though the cell still holds charge. One full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% recalibrates the gauge against the new cell's actual curve and eliminates the early cutoff.

Fast charging not available on the Tab M10 Plus after a battery swap

The Tab M10 Plus uses USB-PD negotiation to enable fast charging, and the charge IC on the board runs through one accepted charge cycle before it unlocks higher current delivery to an unfamiliar cell. Immediately after a swap, the controller defaults to standard 5V charging as a precaution. Plug in using the original charger and cable, let the tablet complete one full charge to 100% without interruption, and USB-PD fast charging becomes available on subsequent cycles.

Frequently Asked Questions

My Tab M10 Plus battery percentage jumps around and shows 80% one minute then drops to 60% — is the new battery faulty?

The fuel gauge IC on the TB-X606F board is still calibrated to the discharge curve of the old cell. A new cell with a different internal resistance causes the gauge to misread voltage and report erratic percentages. This is not a defect in the replacement battery. Run the tablet to automatic shutoff, then charge uninterrupted to 100% — the gauge recalibrates and the percentage display stabilises from that point forward.

The Tab M10 Plus gets noticeably warm near the charging port after fitting the replacement battery — should I be concerned?

The charge IC on the TB-X606F board runs a higher charge current during the constant-current phase when it first encounters a deeply discharged new cell. That elevated current is the source of the warmth, and it tapers off once the cell voltage climbs above 3.7V and the IC switches to constant-voltage mode. Surface temperature during this phase is normal. If the tablet becomes hot to the touch or the charge stops and a fault indicator appears, disconnect and check that the connector is fully seated.

The Tab M10 Plus battery drains noticeably faster than expected when the screen is at full brightness — is this a capacity issue with the replacement cell?

The 10-inch IPS display on the TB-X606F is the single largest current draw in normal use, and at full brightness it pulls significantly more from the cell than at mid-range settings. If the fuel gauge IC has not yet completed a recalibration cycle, it also tends to underreport remaining capacity, making drain appear faster than it is. First, complete one full discharge-to-shutoff and uninterrupted charge to 100% to recalibrate the gauge. Then set brightness to 60–70% — that alone is the most effective step to extend use between charges.
