Selecting the optimal video camera battery helps ensure uninterrupted and efficient shooting experiences. Therefore, this article aims to provide useful information on the different types of batteries for photographers, each with its own chemistry and performance characteristics, and offers practical purchasing tips. Photographers can choose batteries that meet their shooting needs and equipment compatibility by understanding lithium-ion, nickel-metal hydride, and other battery technologies.
Common Types of Video Camera Batteries Used
1. Lithium batteries
Lithium batteries in small video cameras and accessories offer high energy density and a long shelf life. When used as primary cell types, they are single-use for devices that require power over a period of time with light use, such as remote controls. They perform well in a variety of temperatures, operating in relatively cold and warm conditions. This advantage is also adaptable when the term refers to the secondary cell type, such as the lithium-ion battery shown below.
2. Lithium-ion batteries
Lithium-ion camera batteries are a rechargeable battery. They are essential in professional video equipment due to their high energy-to-weight ratio, which means maximum power with minimal weight, offering advantages for handheld or gimbal-mounted cameras. They also have no memory effect, meaning they can be recharged at any discharge level without affecting their capacity and lifespan, which is vital for filming on the go. They are also more environmentally friendly than some nickel-based batteries because they do not contain toxic cadmium.
3. Nickel-Cadmium (NiCd) Batteries
Nickel-cadmium batteries were once dominant in older video camera models. They are less common today due to environmental concerns. Their strength lies in their durability and exceptional performance under heavy use and frequent discharge cycles. They can also provide high current levels for devices requiring sudden power surges. However, NiCd batteries are often heavier than other types of batteries of equivalent capacity and suffer from the memory effect, requiring a complete discharge before recharging to maintain their capacity. As a result, they are less practical for erratic filming schedules.
4. Nickel-Metal Hydride (NiMH) Batteries
Nickel-metal hydride batteries are an evolution of their nickel-cadmium predecessors. They offer higher capacity and fewer environmental concerns without toxic cadmium, providing a steady power output for devices with moderate to high power requirements. They are common for mid-range video cameras and accessories. However, NiMH batteries suffer from a higher self-discharge rate than lithium batteries, discharging more quickly when not in use.
How to Choose the Right Video Camera Battery for Specific Needs
Now that you have a basic understanding of several commonly used battery types, the following tips will help you choose the best final choice to power your filming experiences.
Battery capacity and autonomy
When choosing a video camera battery, look for a higher mAh rating, which indicates the battery's capacity, for extended runtime. A higher capacity battery generally means it can provide power for longer durations. Also, consider your camera's power requirements. For example, DSLRs are known to be power hungry, especially when equipped with flash units or using continuous lights, which can further drain the battery. In these cases, consider carrying lightweight lithium batteries as backup solutions or opting for a V-mount external battery solution.
Dimensions and weight for portability
The physical dimensions and weight of a video camera battery are essential for portability. Lithium-ion batteries are superior due to their lighter weight and compact size. They provide the same power as heavier alternatives. For example, a lithium-ion battery weighs less and is small enough to fit in a small camera bag, unlike a NiCd battery of similar capacity. This is essential for handheld or gimbal-mounted cameras; additional weight affects stability and causes fatigue.
Compatibility with camera accessories
Finally, make sure the video camera battery is compatible with your camera and its accessories. This includes checking the voltage and connector type. For example, a battery with a proprietary connector may not fit a camera that requires a standard DC jack. Additionally, some batteries have built-in USB ports to power additional accessories, such as LED lights or microphones. Choosing batteries that are compatible with universal chargers is also beneficial. This makes charging easier and faster when using multiple batteries during a shoot.
