V-Mount batteries are high-capacity power sources commonly used to run professional cameras, LED lights, monitors, microphones, and other production gear. Inside each pack are multiple lithium-ion cells connected in series to deliver the rated power output shown on the label. One of the most common questions users have is, “How long do V mount batteries last?” In this post, we’ll break it down into two key aspects: battery life and overall lifespan.
If you’re asking how long a V-mount battery can last on a full charge when filming
To begin with, the battery life largely depends on the type of device you’re using.
If you’re operating a high-end camera with 4K recording, your V-Mount battery will deplete much faster compared to when using a simple point-and-shoot camera. Another important factor is the number of devices connected to the same battery — the more equipment you power, the quicker the battery will drain.
Considering these factors, how long can a V-Mount battery typically last? On average, most V-Mount batteries provide between 2 to 6 hours of operation before needing a recharge. However, some higher-capacity models can deliver up to 8 hours or more on a single charge, depending on the available battery power.
To estimate how long a V-mount battery will power your equipment, you can use a simple formula:
Runtime (hours) = Battery Capacity (Wh) ÷ Power Consumption (W)
For example, if you’re using a 99Wh V-mount battery with a camera that consumes 20W, the estimated runtime would be:
99Wh ÷ 20W = 4.9 hours
Keep in mind that this is a theoretical value. Actual runtime may vary depending on factors such as additional accessories (monitors, transmitters, lights), environmental conditions, and battery health. Using higher-capacity batteries (e.g., 150Wh or 190Wh) or multiple batteries in rotation can help extend your shooting time on set.
Three common ways to charge the V-Mount battery
To charge a V-mount battery, use a standard V-mount charger, D-Tap charger, or USB-C PD charger. Modern V-mount batteries, like Moman, support fast charging via USB-C.
🔌V-mount charger/dock: A dedicated V-Mount charger or dock remains the most traditional and often the fastest charging option. These chargers are specifically designed for V-Mount batteries and often feature multiple bays, allowing you to charge two or more batteries at once. To use one, simply slide the battery onto the charging plate until it securely locks in place, then connect the charger to a wall outlet to begin charging.
🔌D-Tap Charger: Many V-Mount batteries include a D-Tap port—a two-pin connector commonly used for both powering accessories and charging the battery itself. To recharge through this port, you’ll need a dedicated D-Tap charger that connects to a wall outlet on one end and features a D-Tap connector on the other. Simply plug the connector into the battery’s D-Tap port to begin charging.
🔌USB-C PD Charger: Many newer V-Mount batteries, particularly compact “mini” models like Moman Power 99, are equipped with a USB-C port that supports Power Delivery (PD) charging. This feature is especially convenient for travel, as it allows users to charge their batteries using standard USB-C laptop or phone chargers. For faster charging, a high-wattage PD charger—typically 45W, 65W, 100W, or higher—is recommended. To charge, simply connect a USB-C cable from a compatible PD charger to the battery’s USB-C port.
Moman Power 99 is a 99Wh V-mount battery with dual D-tap, USB-A, and PD USB-C ports.
If you mean the lifespan of a V-lock battery
How long do V mount batteries last, considering their lifespan? The lifespan can vary widely depending on several factors, including the battery type, age, and how well it’s maintained. Generally, with proper care, a V-mount battery can last anywhere from 2 to 5 years.
To maximize your battery’s lifespan, follow a few simple maintenance practices.
- Keep the battery charged regularly, as leaving it uncharged for long periods can cause it to deteriorate faster.
- Avoid exposing it to extreme temperatures, whether hot or cold, since both can reduce overall battery health.
- Lastly, store the battery in a clean, dry environment when not in use. Moisture and dust can speed up wear and shorten its service life.

Tips for maintaining to ensure a longer lifespan of V-mount batteries
To extend the lifespan of your V-Mount battery, maintain it properly by adhering to safe charging methods, storing it under suitable conditions, and routinely checking its condition.
💡Charging guidelines: Use only the charger recommended by the manufacturer to prevent overcharging, which can shorten the battery’s lifespan. Overcharging may cause the battery to swell and lose capacity. Fully charge the battery before storing it, but avoid leaving it connected to the charger for long periods.
💡Storage recommendations: Keep the battery in a cool, dry environment, away from direct sunlight. The ideal storage temperature ranges from 20°C to 25°C (68°F to 77°F). Extreme heat or cold can harm the battery’s chemistry and reduce its capacity, with high temperatures potentially cutting battery life by up to 25%.
💡Regular monitoring and checks: You should check the battery's voltage and capacity every few months, as recommended by most manufacturers. Use a multimeter to measure the voltage and confirm it stays within the acceptable limits. A significant voltage drop indicates the battery is aging and may need to be replaced or serviced.
💡Maintenance cycling: If you aren't using the battery regularly, you should perform a complete discharge and full recharge cycle every three months. This action is vital for recalibrating the internal Battery Management System (BMS), which helps balance the individual cells and extend the battery's overall lifespan.
💡Prevent deep discharges: To maximize your battery's life, avoid letting it completely discharge often. Deep discharges can drastically reduce its lifespan. For the best performance, try to keep the battery's charge level between 20% and 80%.
Adhering to these guidelines will help you get the most performance and longevity out of your V-mount batteries.
