Energy storage, which is one of the most important issues of energy reliability, is one of the main research areas today. Of the wide variety of methods investigated, the most common is still a variety of batteries.

Hundreds of types of batteries are available to adapt to different needs and environmental conditions. Different batteries should be used according to the purpose and place of use, and it is a real expertise to choose the most suitable one among this variety.

Technical Information About Accumulators

Cell: It is the smallest unit in terms of voltage. It is determined by the chemicals used. For example, it is 2 Volts for Lead-Acid and 1.2 Volts for Nickel-Cadmium.

Number of cycles: Indicates how many times the accumulator can be charged/discharged without losing its properties.

Discharge Depth: Indicates the extent to which the capacity of the battery can be used during discharge. As the discharge depth decreases, the number of cycles increases.

Using and Storage Temperatures: It is one of the important factors that determine the life and capacity of the battery. It shows different effects depending on the type of battery used.

Capacity: It is a measure of how much energy the battery can provide. It is defined as Ampere-hour (AHt) if it is discharged up to a certain value at a certain temperature.

Here, the value of t indicates that the capacity is defined with the condition of drawing constant current for “t” hours at 20C.

For example, the capacity of the battery that will draw 10A current for 10 hours is defined as 100 AH10. This does not mean that the same battery can draw 20 Amps for 5 hours or 100 Amps for 1 hour.
