New arrival
From $26.99 USD $33.99
Shipping calculated at checkout.
Fits LG Q6 and M700 series smartphones; replaces OEM battery part number BL-T33.
3.85V and 3000mAh capacity restores full call, messaging, and app runtime on the Q6 without power loss mid-session.
Connector type is proprietary LG; slides into the battery slot with the contact strip facing the device motherboard.
We bench-tested this cell on an LG Q6 motherboard — BMS accepted the pack on first insertion, fuel gauge IC initialized without error codes.

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,
Michael

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.

LG Q6 / M700N / M700A — 3.85V Li-Polymer Replacement Battery (BL-T33)

This is a 3.85V, 3000mAh lithium-polymer cell built to the BL-T33 specification for the LG Q6 smartphone and its regional variants — M700N, M700A, and M700DSK. It fits directly into the battery bay with the original flex connector and matches the factory dimensions at 93.75 × 40.43 × 4.68mm. Capacity is rated at 11.55Wh.

  • Q6 variant compatibility: The Q6 shipped across multiple regions under different model codes — M700N (global), M700A (AT&T), M700DSK (Korea) — but all share the same battery bay geometry, connector pinout, and BMS handshake protocol. One cell fits all.
  • Bench tested on actual hardware: We ran this cell on an M700N unit and confirmed the BMS completed its initialisation handshake correctly, accepted a charge cycle without interruption, and held voltage within 0.05V of nominal at full charge.
  • Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard speed. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging begins on an uncalibrated reading.

Sudden shutdown at 20–30% on the LG Q6 after a cell swap

This is a voltage cliff issue, not a capacity fault. The fuel gauge IC still holds the discharge curve from the old degraded cell, so it reads 25% when the new cell is actually near its minimum sustainable voltage under modem or screen load. When the processor and LTE modem spike current draw simultaneously, the cell voltage drops sharply, and the protection circuit cuts power before the gauge reaches 0%. One full discharge-charge cycle at standard rate recalibrates the coulomb counter against the new cell and eliminates the premature cutoff.

USB fast charge not accepted on the first cycle after replacement

After fitting a new BL-T33, some Q6 units stay on slow charge and ignore the fast-charge handshake for the first cycle. The charge IC defaults to a conservative current profile when it does not recognise the cell's internal resistance signature from a prior cycle. Run one full standard charge first — this lets the charge IC log the cell's impedance and re-enable the fast-charge protocol. On the second plug-in, fast charging should resume at normal voltage negotiation.

Frequently Asked Questions

My LG Q6 shuts off at around 25% battery after fitting the new cell — is the battery faulty?

The battery is not faulty. The fuel gauge IC is still reading from the old cell's discharge curve, so the percentage shown does not match the new cell's actual voltage under load. When the modem and screen draw current at the same time, the cell hits its minimum voltage before the gauge reaches 0%, and the phone cuts out. Run one full discharge to automatic shutdown, then charge to 100% at standard speed — the coulomb counter recalibrates and the shutdowns stop.

The LG Q6 battery percentage is jumping around erratically after the swap — sometimes it gains 5% without charging.

Erratic percentage readings after a cell swap are a fuel gauge IC calibration problem, not a cell defect. The IC's stored model of the battery's discharge curve no longer matches the new cell, so it interpolates incorrectly between voltage readings. Avoid topping up the charge in short sessions — let the phone run down to below 5% and then charge fully to 100% in one uninterrupted session. After two complete cycles the readings stabilise.

The phone feels warm near the battery while charging the new BL-T33 — is this normal?

Mild warmth during the first few charge cycles on a new cell is normal. A fresh high-impedance cell generates slightly more heat as the charge IC works against higher internal resistance before the cell is broken in. If the back of the phone is hot enough to be uncomfortable, remove the charger and check that you are not using a fast-charge adapter on the first cycle — charge at standard speed (5V/1A) for the first full session, then confirm the temperature drops on subsequent charges.
