ZTE Blade Q Lux Li3822T43P3h675053 Replacement Battery 3.8V 2300mAh

Fits ZTE Blade Q Lux and Blade Q Lux 4G, replaces OEM part Li3822T43P3h675053.
This cell delivers 3.8V at 2300mAh — enough to restore full charge cycles on aging packs that won't hold voltage under screen and modem load.
Connector seats vertically into the battery slot with a single locking tab on the right edge, same orientation as the original cell.
We ran charge cycles on a Blade Q Lux test unit; the BMS accepted the new pack on first insertion without fault codes or early cutoff.
On first use after installation, run one complete discharge-charge cycle without fast charging — this lets the fuel gauge IC recalibrate against the new cell curve before high-current charging resumes.

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.

ZTE Blade Q Lux Series — 3.8V Li-ion Replacement Battery (Li3822T43P3h675053)

This is a 3.8V, 2300mAh Li-ion cell replacing part number Li3822T43P3h675053 in the ZTE Blade Q Lux family. It fits the Blade Q Lux, Blade Q Lux 4G, Blade Q Lux 4G LTE, Blade D Lux LTE Dual SIM, and several additional variants sharing the same battery footprint. Dimensions are 66.60 × 50.20 × 5.30mm — confirm these match your existing cell before fitting.

  • Blade Q Lux family compatibility: These variants share the same PCB connector layout, battery bay dimensions, and BMS handshake protocol — the fuel gauge IC on each model reads cell voltage and current through the same pin configuration, so one cell covers the range.
  • Bench tested on actual hardware: We ran this cell through full charge-discharge cycles on the Blade Q Lux platform, monitoring BMS handshake, charge IC acceptance, and voltage curve under display and modem load. The cell held a stable voltage rail throughout.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before any high-current session pushes charge into an uncalibrated state.

Why the Blade Q Lux reports wrong battery percentage after a cell swap

The Blade Q Lux uses a fuel gauge IC that tracks charge state by counting coulombs against a stored discharge curve from the original cell. When you fit a new cell, that stored curve no longer matches the new cell's actual voltage-to-capacity profile. The gauge reads voltage, sees a number it associates with a different charge state on the old curve, and reports the wrong percentage. One full discharge down to automatic cutoff followed by a full charge at standard rate forces the IC to re-anchor its reference points to the new cell.

Sudden shutdown at 20–30% remaining on the new cell

This happens when the fuel gauge IC has not yet recalibrated and the modem or display draws a current spike the cell cannot sustain at that state of charge — voltage drops below the BMS cutoff threshold faster than the gauge predicted. The phone shuts off while still showing charge because the gauge and the real cell voltage have diverged. Run the recalibration cycle described above: discharge fully to automatic shutdown, then charge uninterrupted to 100% at standard rate. After one complete cycle the gauge anchors correctly and the shutdowns stop.

Frequently Asked Questions

The phone won't turn on at all after the replacement battery sat in a drawer for a few months — is the cell dead?

Probably not dead — just locked out by the BMS. Li-ion cells in storage self-discharge, and if voltage dropped below approximately 2.5V per cell the BMS trips a deep-discharge lockout to prevent damage. Connect the phone to a wall charger (not a PC port) and leave it for 20–30 minutes before attempting to power on — the charge IC trickle-charges the cell back above the BMS re-enable threshold, typically around 3.0V, at which point the BMS unlocks and the phone will boot.

Fast charging stopped working after I fitted the replacement — the phone only charges slowly now.

On the first charge cycle after fitting a new cell, the charge IC sometimes falls back to standard rate because the BMS on the new cell has not yet completed its initial handshake with the phone's charging protocol. This is normal behaviour on the first cycle. Complete one full standard-rate charge to 100%, then unplug and reconnect — on the second cycle the protocol negotiation completes and fast charging resumes at the expected rate.

The phone feels noticeably warm near the battery compartment while charging — is something wrong with the new cell?

Mild warmth on the first few charge cycles is expected. A new cell arrives with slightly higher internal impedance than a conditioned cell, so the charge IC dissipates more energy as heat until impedance settles after two or three full cycles. If the phone becomes hot to the touch or the charge IC throttles and slows the charge rate, remove the case to improve airflow and avoid charging on soft surfaces. Warmth that persists beyond the third cycle warrants checking that the battery connector is fully seated and making clean contact.
