Shipping calculated at checkout.
Fits ZTE Blade V6, Blade X7, Blade D6 smartphones; replaces OEM Li3822T43P3h786032.
Delivers 3.8V at 2200mAh capacity; powers the phone through full daily cycles.
Connector slides into the battery slot behind the rear panel with no locking tab.
We bench-tested the cell on a Blade V6 charge cycle; the BMS accepted input immediately.
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 pushes current into an uncalibrated cell.

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 V6 / X7 / D6 — 3.8V Li-Polymer Replacement Battery (Li3822T43P3h786032)

This is a 3.8V, 2200mAh (8.36Wh) Li-Polymer cell built to replace the original ZTE part number Li3822T43P3h786032. It fits the Blade V6, Blade X7, and Blade D6 smartphones. Dimensions are 76.50 × 59.80 × 3.00mm — match these against your existing cell before installation.

  • Blade V6 / X7 / D6 shared platform: These three models run the same battery bay dimensions, 3.8V nominal rail, and connector pinout, which is why they share one OEM part number. The BMS handshake and charge IC parameters are identical across the trio.
  • Bench tested on actual hardware: We cycled this cell through charge and full discharge on the Blade V6. The onboard BMS held cutoff correctly at both ends — no premature low-voltage lockout and no overcharge event at the top of the cycle.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This allows the fuel gauge IC to map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell — otherwise the percentage readout will drift for days.

Sudden shutdown at 20–30% on the Blade V6 after a cell swap

The Blade V6 fuel gauge IC retains the discharge curve of the old, degraded cell in memory. When voltage drops under modem transmit or screen load, the phone hits a voltage cliff the IC wasn't expecting and cuts power — even though the percentage display still shows 20–30%. This is not a fault with the replacement cell. One full discharge down to automatic shutdown, followed by an uninterrupted charge to 100%, forces the coulomb counter to re-anchor its endpoints. After that cycle the shutdowns stop.

Phone feels warm near the battery during the first charge after installation

A fresh Li-Polymer cell has slightly higher internal impedance than a cell that has been through several cycles. The charge IC on the Blade V6 runs at its standard current rate regardless, so more energy converts to heat across that higher impedance during the first one or two charges. This is normal and tapers off as the cell breaks in. If the phone stays warm well into the third or fourth charge cycle, check that the charge IC is not stuck in fast-charge mode — drop it back to standard 5V/1A charging until the warmth settles.

Frequently Asked Questions

My Blade V6 won't power on at all after the replacement battery sat in a drawer for a few months — is it dead?

The BMS locks out when cell voltage drops below roughly 2.5V during storage, which looks identical to a completely dead phone. Connect the phone to a wall charger — not a PC port — and leave it for 20–30 minutes without pressing any buttons. The charge IC will trickle current into the cell until the BMS re-initialises and voltage recovers above the lockout threshold. Once the boot screen appears, let it charge uninterrupted to 100% before use.

The battery percentage jumps around erratically — it reads 60%, drops to 31%, then climbs back up without charging. What's happening?

The fuel gauge IC on the Blade V6 is calibrated to the discharge curve of the original cell. After a cell swap, the coulomb counter has no valid reference points and interpolates percentage against a curve that no longer matches. The jumps reflect the IC guessing between two poorly anchored endpoints. Run one full discharge to automatic shutdown, then charge to 100% in a single uninterrupted session — this gives the fuel gauge IC the two fixed points it needs to recalculate the curve correctly.

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

On the first cycle after a cell swap, the Blade V6 charge IC sometimes defaults to standard charging rather than accepting the fast-charge protocol, because the BMS on the new cell hasn't yet been recognised in the handshake sequence. Fully discharge the phone to automatic shutdown and then charge it to 100% on the original charger at 5V/2A. After that first complete cycle, reconnect the fast charger — the protocol negotiation should complete normally and fast charging will resume.
