Advantages and Disadvantages of AGM Batteries

AGM batteries are totally sealed batteries. This indicates that there will be no need for user maintenance and that these batteries are leakproof. It is therefore an excellent replacement for the traditional options that are currently on the market. AGM batteries have a high power capacity, which allows them to start cars with a significant amount of current and last a long time. The advantages of AGM batteries are environment-friendly, longer lasting, charge faster, durable, spillproof, More efficient, low self-decaration rate. The disadvantages of AGM batteries are it is more expensive, Reduce capacity over time, are sensitive to overcharging, and have energy issues. Following are some advantages and disadvantages of AGM batteries to better understand this topic.

Benefits or Advantages of AGM batteries

  • They require no maintenance.
  • They are spill-proof.
  • It is durable.
  • It is more efficient than regular batteries.
  • In any orientation, they can be installed.
  • It lasts a longer lifespan than traditional flooded batteries and regular batteries.
  • Environment friendly.
  • They have a low self-discharge rate.
  • They produce minimal gases.
  • Compared to Flooded batteries, AGM batteries charged quickly.
  • They are shock-resistant.
  • Less toxic than traditional gel or flooded cell batteries.
  • It never needs any water.
  • When properly cared for, they outlive SLA batteries.
  • They are vibration-resistant. They were designed to withstand the continuous vibration of military helicopters and aircraft.
  • An AGM battery is considered as maintenance-free as it never needs water.

Drawbacks or Disadvantages of AGM batteries

  • The batteries cost more because of higher manufacturing costs.
  • After a long time, AGM batteries lose some of their capacity to charge.
  • AGM batteries cannot be accurately tested by certain older battery testers.
  • Your AGM battery lifespan may be shortened if you accidentally overcharge it or charge it at a high voltage. Therefore, properly charging AGM batteries is important.
  • They need an AGM battery-specific charger that maintains temperature, voltage, and current.
  • Lead acid batteries have an 80% discharge capacity, but deep-cycle AGM batteries are limited to a 50% discharge capacity. This indicates that appliances will run longer on a single charge for the lead acid battery.
  • These AGM batteries are less tolerant of overcharging and high voltages than flooded batteries. Their lifespan is shortened if they are subjected to these conditions.
  • They can be unsuitable for some applications where it is difficult to fully charge.
  • AGM batteries cannot be properly tested by some older battery testers.
