HTC Flyer P510 Replacement Battery 3.7V 3150mAh

Up to 20% off
New arrival
From $28.99 USD $35.99
Shipping calculated at checkout.
Fits HTC Flyer P510 tablet, replaces OEM battery B2PMW100.
This 3.7V 3150mAh Li-Polymer cell restores full charge cycles on the Flyer after original degradation.
Connector slides into the internal slot with flat orientation; locking tab seats flush against the housing frame.
We bench-tested this pack on the P510 motherboard; BMS accepted charge negotiation without fault codes on first cycle.
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 that appears after a 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.

HTC Flyer P510 — 3.7V Li-Polymer Replacement Battery (B2PMW100)

This is a 3.7V, 3150mAh lithium-polymer replacement battery for the HTC Flyer 7-inch Android tablet (model P510). It replaces OEM part B2PMW100 and fits directly into the Flyer's battery bay. Capacity is rated at 11.66Wh and matches the original cell specification.

  • P510 platform fit: The Flyer uses a single-cell Li-Polymer pack with a proprietary connector and a fuel gauge IC that communicates cell state to Android's battery service. The B2PMW100 form factor is specific to this tablet — 105.30 x 82.25 x 3.00mm — so fitment is straightforward once the back panel is removed.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on P510 hardware. The BMS accepted charge from the Flyer's onboard charge IC without fault flags, and voltage at full charge settled correctly at the expected Li-Polymer ceiling.
  • Fuel gauge recalibration after swap: After installing this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% without interruption. This gives the fuel gauge IC a full reference window against the new cell and corrects the inaccurate percentage readings that appear immediately after a swap.

Why the HTC Flyer shuts down at 15–25% after a battery replacement

The Flyer's fuel gauge IC builds a voltage-to-capacity map over charge cycles. When a new cell goes in, that map still reflects the old battery's discharge curve. Under combined screen and Wi-Fi load, voltage drops faster than the IC predicts, and Android triggers a low-battery shutdown before the gauge reaches zero. One complete discharge-to-shutoff followed by an uninterrupted full charge resets this map against the new cell. After that cycle, the shutdown threshold should stabilise at or below 5%.

Tablet stuck in boot loop immediately after battery installation

A boot loop on first power-up after a swap usually means the battery voltage is too low from storage for the Flyer's charge IC to hand off to the main board correctly. Connect the charger before pressing the power button and leave it for 10–15 minutes. The charge IC needs to bring the cell above approximately 3.0V before the system rail can stabilise. Once the charging LED activates and holds steady, a normal boot will complete.

Frequently Asked Questions

My HTC Flyer shows 60% battery right after installation and then jumps around — is the new battery faulty?

The battery is not faulty. The fuel gauge IC on the P510 is still calibrated to the old cell's discharge profile, so the percentage readings will be erratic until it has a full reference cycle. Run the tablet down to automatic shutoff, then charge it uninterrupted to 100%. After that single cycle, the gauge IC recalibrates against the new cell and percentage reporting stabilises.

The Flyer charges very slowly after swapping the battery — it used to charge faster on the original cell.

The onboard charge IC sometimes starts a new cell at a reduced current rate until it has completed one accepted charge cycle and confirmed the cell's internal resistance is within range. This is a protective ramp-up behaviour, not a fault. Let the tablet complete one full uninterrupted charge to 100%. On the next charge cycle, current delivery should return to the normal rate — check that the adapter output is at least 5V 1A, as a lower-rated adapter will limit charge current regardless of the battery.

The HTC Flyer gets warm near the bottom edge while charging the new battery — is that normal?

Yes. The charge IC is located near the bottom edge of the P510 board, and it dissipates heat while converting input voltage to the cell's charge current. A new Li-Polymer cell draws closer to full charge current in the early cycles than a degraded original cell would, so the warmth is more noticeable than you may remember. If the tablet becomes hot to the touch or shows a temperature warning on screen, disconnect the charger and check that the replacement cell is seated flat with no bulging — a cell seated at an angle can raise internal resistance and increase heat.
