Fits HTC Canary smartphones; replaces OEM battery part number PC26A.
3.7V, 1150mAh lithium-ion cell restores full device power and call capacity.
Connector seats flush into the original battery slot with standard polarity orientation.
We bench-tested this cell in the Canary platform; BMS accepted the new pack on first insertion with no fault codes or charge gating.
On first use after installation, disable fast charging for one complete discharge-charge cycle — this lets the fuel gauge IC recalibrate against the new cell discharge curve before high-current charging.

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 Canary — 3.7V Li-ion Replacement Battery (PC26A)

This is a 3.7V, 1150mAh Li-ion replacement battery for the HTC Canary smartphone. It matches the OEM part number PC26A and fits the original battery compartment without modification. Voltage and capacity are matched to the Canary's charge IC and fuel gauge expectations.

  • HTC Canary compatibility: The Canary uses a single-cell Li-ion pack at 3.7V nominal. The charge IC and BMS handshake are calibrated to this voltage rail. Swapping in a cell outside this spec causes the charge controller to reject the pack or terminate early.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on the HTC Canary. The BMS accepted the pack on first insertion, charge termination triggered at 4.2V, and the fuel gauge IC responded normally across the discharge curve.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's actual discharge curve before high-current charging pushes load into an uncalibrated coulomb counter.

Sudden shutdown at 20–30% on the replacement cell

This happens because the fuel gauge IC is still running a calibration curve built for the old, degraded cell. A fresh cell has a steeper voltage cliff at low charge states — the phone's voltage threshold triggers an emergency shutdown before the reported percentage reaches zero. It is not a fault with the new battery. Run two full discharge cycles from 100% to automatic shutdown without interruption, then charge to 100%. The fuel gauge IC resets its reference points against the new cell's actual voltage curve.

Phone won't power on after the battery sat in storage

Li-ion cells that discharge below 2.5V trigger a BMS lockout to prevent cell damage. If the replacement battery shipped at low state of charge and sat unused, the BMS may have locked out. Connect the Canary to a wall charger — not a PC USB port — and leave it for 20–30 minutes without pressing the power button. The charge IC on the phone delivers a trickle current that brings the cell above the 2.5V threshold and releases the BMS lockout.

Frequently Asked Questions

My HTC Canary keeps shutting off around 25% even though the new battery is fully charged — what's wrong?

The fuel gauge IC is still calibrated to the old cell's discharge curve, so it misjudges where the voltage cliff sits on the new cell. Under screen or modem load, the cell voltage drops faster than the IC predicts, triggering an emergency shutdown before the display hits 0%. Run two complete cycles — drain to automatic shutdown, charge uninterrupted to 100% — and the coulomb counter resets against the new cell's actual curve.

The battery percentage on my Canary is jumping around erratically after fitting this replacement — is the battery faulty?

The cell is not faulty. The fuel gauge IC uses historical charge and discharge data to estimate state of charge, and after a cell swap that reference data no longer matches the new cell's characteristics. Erratic percentage jumps are the IC recalibrating in real time. Complete one full uninterrupted discharge-to-shutdown followed by a full charge to 100%, and the readings will stabilise.

My Canary won't power on at all after I installed the replacement battery — it just shows a blank screen.

If the replacement cell arrived below 2.5V or discharged in storage before installation, the BMS has entered a lockout state to protect the cell. Plug the phone directly into a wall charger and leave it untouched for at least 20 minutes — do not press the power button during this time. The phone's charge IC will deliver trickle current to bring the cell above the 2.5V recovery threshold, at which point the BMS releases and the phone will boot normally.
