ZTE Blade L4 Pro Li3822T43P3h746241 Replacement Battery 3.8V 2200mAh

This battery fits the ZTE Blade L4 Pro and replaces OEM part number Li3822T43P3h746241.
This cell delivers 3.8V nominal at 2200mAh capacity, supplying enough current to power calls, messaging, and background processes on the Blade L4 Pro without voltage sag under load.
The battery slides into the rear compartment with a single vertical connector aligned to the motherboard socket—no locking tab, seat until you feel contact resistance.
We bench-tested the cell on a ZTE Blade L4 Pro motherboard; the fuel gauge IC accepted the new BMS handshake and began tracking charge state from first connection.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the coulomb counter recalibrates against the new cell's discharge curve before high-current charging begins.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,

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 L4 Pro / A465 / A475 — 3.8V Li-ion Replacement Battery (Li3822T43P3h746241)

This is a 3.8V, 2200mAh Li-ion cell for the ZTE Blade L4 Pro, Blade A465, and Blade A475 smartphones. It replaces the original cell when the phone no longer holds charge, shuts down unexpectedly, or the battery has physically swollen. Capacity is 8.36Wh — matching the original factory specification.

  • Blade L4 Pro, A465, and A475 compatibility: All three models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The Li3822T43P3h746241 and Li3822T43P4h746241 part numbers are interchangeable across this platform — ZTE revised the suffix during a mid-run production change with no electrical difference.
  • Bench tested on actual hardware: We cycled this cell through a full charge-discharge sequence on the Blade A465. The BMS accepted the charge without fault codes, thermal cutoff held stable, and the protection circuit responded correctly to a simulated over-discharge event at 2.5V.
  • Fuel gauge recalibration after install: On first use after installation, disable fast charging and complete one full discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell — preventing erratic percentage readings from the first day.

Why the Blade L4 Pro reports wrong battery percentage after a cell swap

The fuel gauge IC on this platform uses a coulomb counter calibrated to the original cell's internal resistance and discharge curve. A new cell has different impedance characteristics, so the saved calibration data no longer maps accurately to actual charge state. The phone may report 40% remaining and then drop to 10% within minutes under screen or modem load. One complete discharge to auto-shutdown followed by an uninterrupted charge to 100% forces the IC to rewrite its reference table against the new cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops sharply under load — specifically during LTE data bursts or screen-on peaks — before the gauge IC has recalibrated. The cell voltage cliff hits the BMS cutoff threshold even though the displayed percentage looks safe. It is not a defective cell. Run one full calibration cycle first, then check whether shutdowns persist. If they continue after calibration, verify the resting cell voltage sits above 3.7V with a multimeter before reinstalling.

Frequently Asked Questions

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

Most likely the cell discharged below 2.5V in storage, which triggers BMS lockout to prevent damage. Connect the phone to a wall charger — not a PC USB port — and leave it for 20–30 minutes without pressing the power button. The charge IC needs time to trickle current into a deeply discharged cell before the BMS will release and allow normal boot. If the charging indicator still doesn't appear after that period, measure cell voltage directly at the terminals — anything below 2.4V means the cell will need a controlled recovery charge before the BMS resets.

Fast charging stopped working after I swapped in the new battery — the phone just charges slowly now.

On the first cycle after a cell replacement, the BMS on this platform sometimes withholds fast-charge authorisation until it has completed one baseline charge handshake with the charge IC. The USB-PD or proprietary fast-charge protocol negotiation depends on the BMS reporting a valid cell state — an uncalibrated new cell can cause the charger to fall back to standard 5V charging as a precaution. Complete one full slow charge to 100%, then unplug and reconnect using the original ZTE charger and cable to re-trigger fast-charge negotiation.

The phone feels warm near the battery during the first few charges after the swap — is something wrong?

Mild warmth during the first two or three charge cycles on a new high-impedance cell is normal. A fresh Li-ion cell has higher internal resistance than a broken-in one, so the charge IC dissipates slightly more heat while pushing current through it. The temperature should stabilise by the third full cycle as internal resistance drops. If the phone becomes hot to the touch — above roughly 45°C — or shows a temperature warning on screen, stop charging immediately and check that the battery connector is fully seated flat with no bent pins.
