Fits JVC GZ-HD620, GZ-HM330, GZ-MS210 and 174+ models; replaces BN-VG107, BN-VG107U, BN-VG107E, BN-VG108, BN-VG108U, and related OEM part numbers.
3.7V nominal, 890mAh capacity delivers 3.29Wh — adequate for short to medium shooting sessions; video recording draws more than stills.
Connector slides straight in vertically; no locking tab, just press until seated; polarity marked on the cell housing.
We bench-tested this pack in a GZ-HD620 body; BMS accepted the cell on first insert without authentication delay; voltage held steady through three discharge cycles.
On first use, insert the cell and run one complete charge cycle through the camera body itself — the JVC firmware updates its fuel gauge after the initial cycle completes.

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.

JVC GZ-HD620 Series — 3.7V Li-ion Replacement Battery (BN-VG107)

This 3.7V, 890mAh Li-ion cell replaces the BN-VG107 battery in JVC camcorders including the GZ-HD620, GZ-HM330, GZ-MS210, and over 170 additional GZ-series models. It slots into the same battery bay and connects via the same three-contact interface as the factory cell. Dimensions are 42.60 × 31.00 × 21.40mm — verify these against your current battery before ordering.

  • GZ-series compatibility: JVC's GZ-HD, GZ-HM, and GZ-MS lines share the same 3.7V single-cell platform and use the same BN-VG107/BN-VG108 footprint. The connector pinout and BMS handshake protocol are consistent across this family, which is why one cell covers such a wide model range.
  • Bench tested on actual hardware: We ran this cell through the GZ-HD620 charge circuit and confirmed the BMS accepted the cell, reported charge status correctly, and held voltage above 3.5V through a full discharge cycle. The protection circuit tripped cleanly at low-voltage threshold without requiring a manual reset.
  • First-use charge cycle on GZ-series bodies: Insert the new cell and charge it fully through the camera body or OEM charger before your first shoot. Some GZ-series bodies need one complete in-camera charge cycle before the battery-remaining indicator maps accurately to the new cell's discharge curve.

Why the GZ-HD620 shows a dead-battery icon on a partially charged replacement cell

The GZ-HD620 uses a voltage-threshold lookup to estimate remaining charge. A new cell's discharge curve starts slightly higher than a worn factory cell, so the camera's indicator can misread the state of charge until the BMS recalibrates. This usually resolves after one full charge-to-discharge cycle run through the camera body. If the icon persists, check that terminal voltage at the contacts reads above 3.6V with a multimeter — anything below that points to a cell that didn't ship fully charged.

Battery percentage jumping erratically during recording on the GZ-HM330 and GZ-MS210

Erratic percentage jumps happen when the camera's fuel-gauge algorithm is calibrating against an unfamiliar discharge curve. The GZ-series processor, sensor, and image stabilisation draw current in bursts, and if the BMS hasn't mapped the new cell's internal resistance yet, the voltage reading swings wider than expected. Run two full charge-discharge cycles entirely within the camera to let the gauge settle. After that, percentage steps should be consistent and track evenly down to the 3.2V cutoff.

Frequently Asked Questions

My GZ-HD620 shows "no battery" or refuses to power on with the new cell installed — what's wrong?

This is a BMS authentication check that some GZ-series bodies run on first contact with a new cell. Insert the battery, connect the camera to its OEM charger, and let it complete one full charge cycle before attempting to power on. That single charge cycle writes the cell to the camera's accepted-battery register. If the body still rejects it after a full charge, clean the three contact pads on both the battery and bay with a dry cloth — oxidation on those contacts causes the same symptom.

The battery percentage on my GZ-HM330 drops from 80% to 20% with no warning mid-shoot — is the cell faulty?

It's not a faulty cell — it's the camera's voltage-threshold indicator mapping against the wrong discharge curve. New Li-ion cells have a slightly different voltage-versus-capacity profile than the worn factory cell the camera learned on. The gauge recalibrates after two full charge-discharge cycles run through the camera body. After calibration, the steps will track evenly; if large jumps persist past two cycles, measure resting voltage after a full charge — it should read 4.1–4.2V at the contacts.

My GZ-MS210 runs through this replacement cell noticeably faster in cold weather than indoors — normal?

Cold temperatures raise a Li-ion cell's internal resistance, which causes voltage to sag faster under the combined draw of the sensor, processor, and stabilisation system. At around 0°C, effective capacity can drop 15–20% compared to room temperature — this is a chemistry-level behaviour, not a defect. Keep a spare cell in an inside jacket pocket to maintain its temperature, then swap it in when the in-camera cell sags. At room temperature both cells should recover close to their rated 890mAh delivery.
