What is a UPS battery?

4th, January 2019

A UPS device consists of components such as Battery, a charge rectifier ( Rectifier ) or AC to DC converter, DC to AC converter or INVENTER INVERTER > ) and charger is formed.

UPS device is an electronic device that is designed to provide constant energy for consumer devices, which is very sensitive to disturbances in the network and disconnection and connection of electricity, and due to its very high sensitivity to outages and power surges medical and hospital complexes, Telecommunications , computer etc., are among the required equipment of these collections.

Changes such as a sudden increase or decrease in voltage, types of momentary or permanent distortion, frequency change, are examples of problems created on the urban power grid. Due to the advancement of technology and the devices produced and their high precision and sensitivities and their special and special applications, they need equipment such as a power supply without any interruption to provide stable and reliable voltage and frequency.

UPSs are designed and built to deal with AC power problems in systems. UPSs can, for example, be used to protect a typical PC ranging from a few hundred VA to several million VA for Telecom and Computer Centers and Large industrial strong> strong> strong> strong> strong>

The presence of a UPS battery in a UPS system ensures that in the event of a power outage, the UPS functions will continue properly.

A UPS will never work properly without batteries. In fact, the duty of the UPS battery is to store the energy of the electric current, which provides the necessary energy during a power outage. UPS batteries are produced in three long, medium and short life models.

Batteries that can be used in the UPS device

The types of batteries that can be used in UPS are nickel-cadmium and lead-acid batteries. The best and most suitable battery for UPS is lead acid type which has two types or The lid is open and dry or the lid is closed. Dry battery or closed cap is more popular due to the fact that it requires little service and maintenance and has a longer life than other types. If we expect special conditions or special functions from the battery, the type of battery or the voltage of the UPS battery may be different. Nickel cadmium battery is used for long life.

In order to choose the right battery UPS, it is necessary to have information in this field. Some UPSs do not accept all types of batteries as connected batteries, so their manufacturer mentions the type of batteries that can be connected to them. Apart from these cases, environmental factors and physical characteristics and operation of the battery are among the factors that affect the choice of the right battery.

lead acid , Nickel Cadmium, Lithium and Alkaline are generally batteries used for UPSs. The best type of battery is lead acid battery which is available in the market with 12 volts. The only battery with a lifespan of more than 10 years is a nickel-cadmium battery.

Environmental factors influencing the selection of suitable UPS

The meaning of influencing environmental factors are factors such as the temperature of the system location and humidity, as well as the biological effects it has on the environment. In terms of humidity, balanced conditions should be created for the UPS battery so as not to damage the terminal and connections between the UPS battery and other equipment.

In relation to the temperature, it is worth mentioning that if the UPS installation location has a temperature range of 0 to 40 degrees Celsius, a lead acid battery can be used, and if the air temperature is lower or higher than this range, a nickel battery can be used. Cadmium, which has a longer lifespan and naturally a higher cost, is used. If you use a normal battery, there is a possibility of creating environmental hazards due to the gases emitted from the battery.

Meanwhile, in the closed-cap UPS battery, charging and discharging operations are performed in a closed cell house, which does not pose biological risks to work environments. The second effective factor is the physical characteristics of the UPS battery. The size and volume of the UPS battery, which creates a limitation related to the space of the battery cabinet, as well as its arrangement and access, is one of the factors that must be considered.

Another feature of UPS battery which is related to its operation is the charge cycle efficiency component. And discharge is more important in cases where energy sources are low and the battery can be used more. It should also be kept in mind that all rechargeable batteries have limitations and issues for recharging that should be considered before choosing.

Even the type of charger in these batteries is effective and useful. Another feature of the UPS battery that should be considered is its useful life. The useful life of lead-acid batteries is normally 5 to 6 years, and in the best case, they have a useful life of 10 to 12 years. The useful life of batteries depends on the environmental conditions of the battery location. If the UPS battery works at high temperature, its useful life will be greatly reduced. Also, the duration and intensity of charging and discharging the battery depends on the battery life. For example, if it is charged for a long time or with a high intensity, the battery life will decrease and may cause its failure.
