To ensure high-quality and long-term operation of photographic equipment, it is recommended to use batteries that are suitable for the standard size.
Despite the fact that batteries can be effectively used for these purposes, rechargeable power supplies can save money if the device is used often. The main characteristics, as well as which criteria should be considered when selecting a new power source, will be described in detail in this article.

Varieties of Power Supplies
In stores, you can find a large number of models of power supplies that can be used to change the dead batteries of the camera.
It can be difficult to determine whether a battery can be used for a specific device model. Most often, photographic equipment uses two types of batteries: finger-type and specialized.
Finger AA
Size AA can be found in low-cost photography devices. The advantage of using such products is their versatility.
The necessary designations are almost always indicated on the case of such batteries, but in many cases this information turns out to be superfluous, since it is very easy to identify a finger-type battery.
Usually, AA batteries They are installed in inexpensive cameras, in more complex equipment, original products are often used that are suitable only for a particular model of equipment.
Specialized
In expensive models, mainly specialized batteries are used, suitable only for a specific model of the camera. Such products are very high quality and can last for many years before you need to replace the battery.
The disadvantages of such products are the inability to quickly buy a battery. Often, specialized devices have to be purchased to order.
Types of Power Supplies
The possibility of charging it, as well as use in certain conditions, depends on the type of power source. The main separation of such power sources is carried out on batteries and rechargeable batteries (batteries).
Batteries
Batteries are inexpensive, and you can buy such products even at the grocery supermarket. If you stock up on a large number of such products and have at hand a sufficient number of them, then you can completely do without acquiring any other batteries.
This type of power supply is not suitable only for installation on expensive models of cameras, the design of which provides the ability to connect only a specialized (original) battery.
Saline. The advantage of this type of battery is its low cost. Such products are several times cheaper than alkaline, and an order of magnitude - lithium. This is the advantage salt power supplies can be considered exhausted.
In cameras, which provide the ability to install AA batteries, such products sit very quickly. Especially if used at night with a flash.
Alkaline In digital cameras alkaline batteries For a long time they were considered optimal sources of electricity. Such products have a significantly higher capacity compared to salt batteries.
At the same time, they significantly complicate the equipment, which with prolonged use of portable devices can be very noticeable. This type of battery is ideal for occasions when the camera is used from time to time.
Lithium If the design of the camera provides the ability to install finger batteries, then lithium products are ideal for providing this type of equipment with electric current. The main advantages are increased capacity, low weight and low self-discharge.
High price is the only drawback lithium batteries, therefore, with the daily use of photographic equipment, you should think about purchasing batteries of a suitable size.
Batteries
To provide cameras with electric current, AA batteries can be used. Despite the low voltage (1.2 V), such products will save a considerable amount of money, because many battery models can be charged up to 1000 times without loss of capacity.
If an original battery is installed in the camera, then the owner of the photographic equipment simply has no other choice but to look for a specialized source of electricity for sale.
Ni-Mh. NiMH batteries are very common products that are effectively used in various portable electrical devices. Products have high capacity indicators, so they can work for a long time without recharging.
Unfortunately, such devices have serious drawbacks, including high heat during charging, increased self-discharge and inoperability at temperatures below minus 10 degrees Celsius.
Ni-Cd. Main advantage nickel cadmium Battery life is low cost. The disadvantages of such products include the presence of a memory effect, so the power sources are completely discharged before being reinserted into the charger.
Li-ion. Lithium-ion batteries are the most durable products, so they can be used even in external batteries. A battery of this type holds a charge perfectly, so many models of expensive cameras are equipped with compact original products of this type.
Disadvantages Li-ion batteries can be attributed to the fact that they quickly sit in the cold. The high cost of products also does not allow the use of such batteries everywhere.
What is important to consider when choosing a power source
When selecting finger batteries, it is recommended to give preference to lithium products. The high cost of such elements is more than offset by long work and low weight. Care must be taken not to confuse batteries with batteries of this type.
Rechargeable lithium power sources have a voltage of 3.7 volts at the terminals instead of one and a half. Nickel-zinc batteries are also not recommended because of the increased voltage, which will be especially noticeable when connecting cells in series.
Which manufacturers should you pay attention to
By purchasing products from well-known manufacturers, there is no doubt in the high quality of products. Regardless of whether batteries are bought or batteries, it is recommended to pay attention to the following brands:
Do not use cheap Chinese counterparts to replace branded products. In this case, not only will the operating time be affected, but also the safety of the operation of photographic equipment will be a big question.
