Panasonic CGA-D54 AG-DVC62 Replacement Battery 7.4V 5400mAh

Up to 19% off
New arrival
From $46.99 USD $57.99
Shipping calculated at checkout.
Fits Panasonic AG-DVC62, NV-MX500, NV-MX350, NV-GX7 and replaces OEM part numbers CGA-D54, CGA-D54SE, VW-VBD55, CGR-D54S, and CGP-D54S.
Voltage runs 7.4V; capacity is 5400mAh—sufficient for extended MiniDV shooting without mid-session swaps on standard recording loads.
Connector type is proprietary Panasonic slide-lock; tab seats fully into the AG-DVC62 battery chamber with audible click and positive mechanical hold.
We bench-tested this cell through a full discharge cycle on the AG-DVC62 body; BMS accepted the new pack on first insertion without authentication delay or voltage-threshold errors.
On first load into the AG-DVC62, run one complete charge cycle through the camera body itself before extended video recording—the Panasonic BMS requires internal charge recognition to map the new cell's discharge curve to the remaining-battery display.

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.

Panasonic AG-DVC62 / NV-MX500 Series — 7.4V Li-ion Replacement Battery (CGA-D54)

This 7.4V 5400mAh Li-ion cell replaces the CGA-D54 battery pack used in Panasonic MiniDV professional camcorders. It fits the AG-DVC62, NV-MX500, NV-MX350, NV-GX7, and over 130 additional Panasonic models sharing the same battery bay and connector footprint. Capacity is drawn from product data: 5400mAh / 39.96Wh.

  • AG-DVC62 and NV-series compatibility: These models share a common 7.4V two-cell Li-ion architecture with the same D-series connector and BMS communication protocol. One cell format covers the full broadcast and prosumer MiniDV lineup from this generation.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Panasonic MiniDV body. The BMS accepted the cell without fault flags, and protection circuitry tripped correctly at both the low-voltage cutoff and during a simulated overload event.
  • First charge cycle on the AG-DVC62: On first install, charge the battery inside the camera body or OEM charger before shooting. Some Panasonic MiniDV BMS units require one in-body charge cycle to map the new cell's discharge curve and display accurate battery-remaining percentage on the viewfinder.

Battery percentage jumping erratically on the AG-DVC62 viewfinder

The AG-DVC62 uses a voltage-threshold lookup table to estimate remaining charge. A new Li-ion cell has a slightly different discharge curve shape than an aged original cell, so the camera's BMS maps voltage readings to wrong percentage steps. This is most visible in the middle of the discharge — the indicator can drop from 60% to 30% in seconds, then hold steady. One full charge-discharge cycle via the OEM charger recalibrates the table. After that cycle, the percentage display tracks the cell closely at all charge levels.

Camera body warm under sustained AG-DVC62 video recording

During continuous recording, the AG-DVC62 draws simultaneously from the sensor, tape transport motor, LCD panel, and image stabilisation system. Combined, this load is significantly higher than standby or menu use. The cell surface and camera body warming up is normal under this combined draw — it does not indicate a fault. If the body becomes hot to the touch and recording stops unexpectedly, check that the battery terminal contacts are clean and making full contact; oxidised pins increase resistance and generate extra heat at the junction.

Frequently Asked Questions

My AG-DVC62 shows a "no battery" warning even though the replacement cell is fully charged — why?

The AG-DVC62 BMS runs an authentication check on first contact with a new cell. If the camera hasn't completed a charge handshake with this specific cell yet, it can reject the pack entirely rather than displaying a low charge warning. Insert the battery and charge it fully inside the camera body using the OEM charger before attempting to record. One completed in-camera charge cycle is usually enough for the BMS to accept the cell and clear the warning.

The battery percentage on my NV-MX500 drops fast at the start of a shoot, then seems to recover — is the cell faulty?

This is a discharge curve mismatch, not a faulty cell. The NV-MX500's fuel gauge maps voltage thresholds calibrated to an aged original cell — a fresh 5400mAh cell holds voltage higher for longer early in discharge, which confuses the lookup table and causes a steep initial drop followed by a plateau. Run one full charge-discharge cycle in the camera body. After that, the gauge recalibrates to the new cell's curve and the percentage tracks more evenly across the full discharge.

Flash recycling on my Panasonic camcorder is slower near the end of the charge — is that the battery or the flash unit?

Near the end of a Li-ion discharge cycle, cell voltage sags under the capacitor recharge current the flash draws between shots. The capacitor takes longer to reach full charge voltage when the supply rail is low, so recycling slows noticeably in the last 15–20% of capacity. The flash unit itself is not the cause. To confirm the battery is the variable, charge the cell to full and test recycling speed again — if it returns to normal speed above 3.5V per cell (7.0V pack voltage), the cell is working correctly.
