The lifespan of an Absorbent Glass Mat (AGM) battery for powered access equipment is a crucial factor for both equipment operators and battery suppliers like us. Powered access equipment, such as boom lifts and scissor lifts, rely heavily on reliable battery performance to ensure safe and efficient operation. In this blog, we'll delve into the factors that influence the lifespan of AGM batteries in powered access applications, typical lifespan expectations, and how to maximize their longevity.
Factors Influencing AGM Battery Lifespan
1. Depth of Discharge (DoD)
The depth of discharge refers to the percentage of the battery's capacity that has been used before recharging. AGM batteries for powered access are designed to handle a certain level of DoD. Generally, the deeper the discharge, the shorter the battery's lifespan. For example, if a battery is frequently discharged to 80% or more of its capacity, it will experience more stress and degradation compared to a battery that is typically discharged to only 20 - 30%. In powered access applications, operators should aim to keep the DoD as low as possible. This might mean recharging the battery more frequently during the workday, even if the equipment is not fully depleted.
2. Charging Practices
Proper charging is essential for the longevity of AGM batteries. Over - charging can cause the battery to overheat, leading to the breakdown of the electrolyte and the plates inside the battery. On the other hand, under - charging can result in sulfation, where lead sulfate crystals build up on the battery plates, reducing the battery's capacity over time. Using a high - quality charger specifically designed for AGM batteries is crucial. These chargers are programmed to deliver the correct voltage and current at different stages of the charging process, ensuring a full and safe charge.
3. Operating Temperature
Temperature has a significant impact on the performance and lifespan of AGM batteries. High temperatures can accelerate the chemical reactions inside the battery, causing faster degradation of the battery components. In contrast, low temperatures can reduce the battery's capacity and increase its internal resistance. For powered access equipment, which may be used in a variety of environmental conditions, it's important to consider temperature management. In hot climates, providing proper ventilation for the battery compartment can help dissipate heat. In cold climates, using battery heaters or storing the equipment in a heated area when not in use can improve battery performance.
4. Maintenance
Although AGM batteries are considered maintenance - free compared to traditional flooded lead - acid batteries, some basic maintenance is still required. Regularly inspecting the battery for signs of damage, such as cracks or leaks, and cleaning the terminals to prevent corrosion can extend the battery's lifespan. Additionally, checking the battery's state of charge and voltage periodically can help identify any potential issues early on.
Typical Lifespan Expectations
The lifespan of an AGM battery for powered access equipment can vary widely depending on the factors mentioned above. On average, a well - maintained AGM battery in a powered access application can last between 3 to 5 years. However, in some cases, with optimal operating conditions and proper maintenance, the battery can last up to 7 years or more.
For example, in a controlled indoor environment where the temperature is stable, the DoD is kept low, and the charging practices are correct, the battery is likely to have a longer lifespan. Conversely, in a harsh outdoor environment with extreme temperatures and frequent deep discharges, the battery's lifespan may be significantly reduced.
Maximizing AGM Battery Lifespan
1. Optimize Depth of Discharge
As mentioned earlier, keeping the DoD low is key to extending the battery's lifespan. Equipment operators should be trained to monitor the battery's charge level and recharge the battery before it reaches a critical level. For example, setting a reminder to recharge the battery when it reaches 50% capacity can help prevent deep discharges.
2. Use the Right Charger
Investing in a high - quality charger designed for AGM batteries is a wise decision. These chargers are equipped with features such as multi - stage charging, which can adjust the charging current and voltage according to the battery's state of charge. This helps to prevent over - charging and under - charging, ensuring a longer battery lifespan.
3. Manage Operating Temperature
To manage the operating temperature, equipment manufacturers can design battery compartments with proper ventilation systems. In addition, operators can take steps to protect the battery from extreme temperatures. For example, during hot summer days, parking the powered access equipment in the shade can help keep the battery cool.
4. Regular Maintenance
Performing regular maintenance tasks, such as terminal cleaning and visual inspections, can go a long way in extending the battery's lifespan. A simple inspection can help detect any potential issues early, allowing for timely repairs or replacements.
