  2. Voltage irregularities
  3. Reduced capacity

These symptoms can vary in severity and sometimes overlap. Therefore, it is essential to monitor multiple indicators before concluding battery health.

  1. Physical Deformities:
    Physical deformities indicate that the AGM battery may have experienced damage. This includes bulging, leaks, or corrosion on terminals. Bulging occurs due to gas buildup inside the battery. This gas builds up when the battery is overcharged or if it experiences a short circuit. The manufacturer, Odyssey Battery, notes that physical changes are signs of internal damage. Corrosion may manifest around the battery terminals, which can lead to poor connections and further issues.

  2. Voltage Irregularities:
    Voltage irregularities reflect potential battery problems. An AGM battery typically operates within a voltage range of 12.6 to 12.8 volts when fully charged. A reading below 12.4 volts indicates a possible issue. This can be caused by deep discharges or extended periods of inactivity. Furthermore, excessive voltage during charging can damage the battery’s internal seals and components, leading to reduced performance. According to a study by the Battery Council International in 2019, voltage drops of more than 0.5 volts from the standard indicate potential complications.

  3. Reduced Capacity:
    Reduced capacity signifies that the AGM battery cannot hold a charge effectively. This means the battery drains more quickly during use. For instance, if an AGM battery is designed for 100 Ah but only delivers 70 Ah, it is likely damaged. Factors such as age, overuse, and frequent deep discharges contribute to capacity loss. Studies show that AGM batteries can lose up to 30% of their capacity if not maintained properly. According to a report by the International Journal of Electrical Engineering in 2021, regular performance testing is essential to avoid severe capacity degradation.
