battery voltage during discharge time in Zener Battery ZB seires
Battery capacity is the product of the discharge current and the time it takes for the battery voltage to reach the specified minimum. This diagram shows the decrease in battery voltage over time under different discharge currents. For example, it shows that after about 12 minutes, if a battery with 2 times the discharge capacity and current is drawn from it, its voltage drops from 12 volts to less than 8 volts. This diagram, with the help of discharge current tables, determines how long it takes for the voltage to reach the final limit of the table for a particular discharge current.
battery capacity with temperature in Zener Battery ZB seires
Battery capacity is a function of ambient temperature and battery discharge rate. Low temperatures reduce battery capacity and high temperatures can damage it. This diagram shows that the capacity of the battery under different charging currents varies from three times the capacity to 0.05 times its capacity at different temperatures, and shows that the temperature must be raised to charge the battery; But if the temperature exceeds 25 degrees Celsius, it will no longer have much effect and we will have saturation in the graph; So to balance the stored capacity and output and maintain battery life, it is best to charge / discharge the battery at 25 degrees Celsius.
Life experience with temperature in Zener Battery ZB seires
This diagram shows the life of Zener ZB series batteries based on their discharge over the years of use in different temperature conditions. Examination of this diagram shows, for example, that if the temperature rises to 32 degrees Celsius (7 degrees above the ideal temperature), the battery life will be reduced by about half.
battery capacity with number of cycles in Zener Battery ZB seires
This diagram shows that if the battery is subjected to certain conditions and with different discharge depths (DOD) [this means charging and being used to a certain level, for example 50%], the number of cycles that have been charged and discharged, in The amount of final capacity it can maintain is affected.
If the batteries are discharged with a higher DOD (per cycle), the capacity of the battery to store energy in cycles of about four hundredths of a second will decrease rapidly. (That is, for a load after 400 hrs, the battery capacity is reduced to 50% instead of 100%.) This diagram shows that if only up to 30% of the battery capacity is used per discharge under the above conditions, its life is up to about 1,200 cycles. Will go up; Of course, this also has another meaning, which is that if we use a battery with a higher nominal capacity for a shorter time and use a small capacity, its annual life and the number of times it will be charged and discharged will increase.
The selling price of the Zener ZB series battery varies according to the requested capacity. For information on inventory, price list and purchase of different capacities of this battery, contact the sales department of Zener Engineering Company.
