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.

LG G6 Series — 3.8V Li-Polymer Replacement Battery (BL-T32)

This is a 3300mAh, 3.8V Li-Polymer replacement battery for the LG G6 smartphone. It fits the G6, G6 TD-LTE, LS993, AS993, and over two dozen additional G6 variants. OEM part numbers are BL-T32 and EAC63438701.

  • G6 variant compatibility: The LS993 (Sprint), AS993 (AT&T), and TD-LTE variants all share the same 3.8V cell format, connector pinout, and BMS communication protocol — one cell works across the entire G6 platform.
  • Bench tested on actual hardware: We ran this cell in an LG G6 and confirmed the BMS handshake completes normally, charge current ramps correctly through CC/CV stages, and the fuel gauge IC reads cell voltage without fault codes.
  • First-cycle fast charge protocol: 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's discharge curve before high-current charging pushes into an uncalibrated state.

Why the G6 reports wrong battery percentage after a cell swap

The G6 uses a coulomb counter and a stored discharge curve to estimate state of charge. When you replace the cell, the coulomb counter is still calibrated to the old cell's curve. The phone reads voltage correctly but maps it to the wrong percentage. One full discharge to automatic shutdown, followed by an uninterrupted charge to 100%, resets the curve and corrects the readout.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops sharply under modem or display load — what's called a voltage cliff. The G6's processor and LTE modem together draw enough current to pull cell voltage below the BMS cutoff threshold before the fuel gauge reports 0%. The BMS trips the output to protect the cell even though the percentage looks fine on screen. Charge the phone to 100%, then run one full cycle without fast charge — if the shutdowns stop, the gauge has recalibrated. If they continue, check that cell resting voltage reads at least 3.85V after a full charge.

Frequently Asked Questions

My LG G6 won't turn on at all after the replacement battery sat in a drawer for a few months — is the cell dead?

The BMS locks out the cell when voltage drops below roughly 2.5V during storage, which cuts the output circuit entirely. Plug in a charger and leave it connected for 15–20 minutes before attempting to power on — the charge IC needs to trickle current into the cell before the BMS re-enables the output. If the screen shows any charging indicator after that window, the cell is recovering. If there's no response after 30 minutes on charge, check that the battery connector is fully seated and the flex cable isn't lifted at the corner.

Fast charging stopped working the first time I plugged in after fitting this battery — was it working before?

On the first cycle after a cell swap, the G6's USB-PD and Qualcomm Quick Charge handshake can fail because the charge IC is negotiating with an uncalibrated BMS. The phone falls back to standard 5V charging as a safety measure, not a fault. Complete one full standard charge to 100%, then discharge normally and charge again — fast charge typically re-engages on the second cycle once the BMS and charge IC have completed one full negotiation sequence.

The battery percentage jumps around erratically — it reads 45%, then skips to 60%, then drops to 30% within minutes. What's causing that?

The fuel gauge IC is recalibrating its coulomb counter against the new cell's actual impedance and discharge curve, which it hasn't seen before. Until it completes that process, percentage readings are unreliable. Run the phone from 100% down to automatic shutdown without interrupting the discharge, then charge in one unbroken session to 100% with fast charge disabled. After that cycle, the fuel gauge will have enough data to map the new cell curve accurately and the jumping should stop.
