Lead-acid battery (AGM) service life and maintenance

    Lead-acid battery (Absorbent Glass Mat, AGM) is a sealed lead-acid battery, due to its unique design, the battery has more advantages in service life, shock resistance and rapid discharge performance than the traditional liquid lead-acid battery. Understanding the service life of AGM lead-acid batteries and how to maintain them reasonably can help users maximize their performance and extend their life.

AGM lead-acid battery detailed introduction

    AGM lead-acid batteries use glass fiber dividers to absorb and fix the electrolyte, which reduces the internal movement of the battery while maintaining sufficient contact between the active substance and the electrolyte, which makes the AGM battery have high charging efficiency and discharge capacity. At the same time, because the AGM battery is closed design, there is no need to maintain and add water, which reduces the maintenance cost and extends the service life.

AGM lead-acid batteries are commonly used in UPS(uninterruptible power supply), solar energy storage systems, emergency lights, security and alarm systems, medical equipment, power tools, electric bicycles and other areas that require a reliable power supply.


AGM service life of the lead-acid battery

& have spent   Generally, the design life of high-quality AGM lead-acid batteries is between 5 and 7 years. However, the actual life can be affected by a number of factors, such as charge and discharge cycle, depth, frequency, ambient temperature, and how the battery is managed. Using the correct charge and discharge management of the battery, as well as avoiding the use of extreme temperatures, can greatly extend the service life of the AGM battery.

Battery life is also closely related to the way it is used. For example, if an AGM battery is often in a state of charge but rarely undergoes deep discharge, it may have a longer service life. On the contrary, frequent deep discharges and undercharging can shorten battery life.

AGM lead-acid battery maintenance and management

    In order to ensure that AGM lead-acid batteries can effectively extend their service life, they must be properly maintained and managed. Here are some recommended maintenance measures:

                1. Periodically check whether the battery terminal and cable are clean and tight. Corrosion or loosening can cause poor contact or electrical failure.

                2. Avoid using and storing AGM batteries at high temperatures. For every 10 ° C increase in ambient temperature, battery life decreases by approximately 50%.

                3. Avoid excessive charge and discharge. Battery discharge to less than 50% before charging can extend the life to the maximum, and the battery is fully discharged after each charge, which will greatly shorten the service life of the battery.

                4. Use the right charger and charging mode. Different types and brands of AGM batteries have different charging parameters, and using the wrong charger or setting can damage the battery or shorten its service life.

                5. Prevent the battery from being discharged for a long time. Batteries left in a state of discharge for a long time are prone to sulfation, in which the active substance is deposited on the electrode plate in a hard crystalline form, which permanently reduces the capacity of the battery.

    Through the reasonable application of the above measures, the service cycle and life of AGM lead-acid batteries can be significantly improved, still, all batteries will eventually come to the end of life because of changes in materials and chemical properties. Therefore, rational use and maintenance is essential, and following the correct maintenance steps can maximize the use of AGM lead-acid batteries.

      AGM lead-acid batteries are an efficient, reliable and low maintenance power solution. By understanding the basics of batteries and adopting appropriate maintenance measures, users can ensure their deep recycling and extended life.
