Factors affecting battery cycle life

The battery cycle life refers to the number of charge and discharge cycles that a battery can undergo before its performance begins to degrade. Solar panel installations use batteries to store excess energy produced by the panels for later use. It is, therefore, essential to understand the factors that affect battery cycle life to ensure that the batteries offer optimal performance for a long time.

One of the primary factors affecting battery cycle life is temperature. High temperatures can increase the rate of chemical reactions inside the battery, leading to a faster degradation of the battery’s components. Similarly, very low temperatures can slow down the same chemical reactions, which is also detrimental to the battery’s performance. Experts recommend keeping the batteries within a temperature range of 15°C to 35°C for optimal performance and longevity.

Another factor affecting battery cycle life is the depth of discharge. Batteries that are discharged to a high capacity, that is, below 50%, tend to have a shorter life cycle. It is essential to keep the discharge depth as shallow as possible to prolong the battery’s life cycle. Setting the battery’s charging and discharging limits can help keep the depth of discharge within the recommended range.

The charging voltage and current also have a significant impact on battery cycle life. Charging the batteries at a high voltage or current can result in excessive heat generating, leading to battery damage.
