How Long Do AGM Batteries Last?

AGM batteries are considered efficient and durable and can outperform many batteries in the market. The battery has an absorbent glass mat that accounts for its enhanced performance and long lifespan. These batteries are presently the most preferred choice for heavier applications like power sports cars and commercial vehicles because of their considerably higher power. However, before buying an AGM battery, you may wonder how long these batteries last?

AGM batteries typically last anywhere between 3 years to 5 years; however, they can last up to 8 years depending on how well they are maintained.

Factors affecting AGM batteries’ lifespan

According to reviews, AGM batteries have a longer lifespan than most ordinary batteries; however, a few factors may affect the lifespan. Here are some of the factors:

  • Time: batteries that are left unused for a long degrade. Time is a significant factor that harms battery life. The longer your battery sits unused, the shorter its life expectancy will be. Even if you only drive your car for a few minutes every day, you may expect a longer battery life than if you don’t use it for a long time. In addition, unused batteries will need to be recharged more frequently than those utilized regularly. It is to maintain the charge when it is used again. 
  • Temperature: Climate factors have a significant impact because the freezing temperature slows the chemical reaction inside the battery. The batteries are unable to work to their full potential in cold weather. It also lowers the capacity of the batteries to keep a charge, resulting in faster discharges. Hot temperature, too, is not suitable for a car battery. According to many studies, car batteries fail more frequently in hot weather than in really cold weather. The heat generated by the acid and water mixture inside the battery and the increased temperature cause heat dissipation to be slower.
  • The Alternator: The alternator in your car generates energy and recharges the car battery. It keeps the battery alive to keep running the car. If the alternator fails to charge the battery, it will discharge significantly faster than usual. In typical conditions, your battery can be depleted in as little as a year or even sooner in extreme heat or cold. The only way to avoid this is to keep a close eye on your battery life and make sure it’s working correctly.
  • Sulfating: Sulfate buildup on the surface of the battery plates occasionally occurs, referred to as sulfating. If proper care is not performed appropriately, this is a critical condition that can completely ruin your battery; when a layer of sulfate forms on battery plates, the ability to hold a charge declines over time at a much faster rate than usual.
  • Complete battery discharging: It’s tough to fully recharge an AGM battery once it’s been fully depleted. It could be the result of a defective alternator or charging mechanism. As the battery can no longer hold the same amount of charge as before, the battery’s estimated lifespan is considerably reduced. As a result, if you want to extend the life of your battery, you must ensure that it is not entirely discharged.
  • Overcharging is one of the most common causes of AGM battery failure as it is particularly harmful to AGM. In addition, when it is done frequently, it usually causes cell damage.

Ways to extend your AGM batteries life?

The AGM batteries’ lifespan can be extended by taking following specific guidelines. Here is a list of ways you can extend your batteries lifespan:

  • The most important thing is Regular maintenance. It also involves regular cleaning and technical inspection, and health checks.
  • Make sure you only charge your AGM battery with the charger recommended by the battery’s manufacturer. Different AGM batteries use different chargers, each with a different voltage capacity.
  • In the case of lead-acid batteries, partial charging should be avoided because it may reduce the battery’s ability to hold a full charge.
  • you might think about changing your driving style if you’re having problems with your battery frequently,
  • Inspect your vehicle to see if any battery-related components are malfunctioning.

Do AGM batteries last longer than other types of batteries?

AGM batteries are made with advanced technologies to fit the new cars made. Not only do AGM batteries produce more energy, but with proper care can last longer than a lot of batteries on the market. The battery is spillproof with glass mat technology which makes it maintenance-free. In addition, AGM batteries typically will last longer than other brands of car batteries because it uses pure lead.

AGM batteries Advantages over other batteries

  • There is an absorbed glass mat effect. It absorbs the liquid in the array, ensuring that it remains dry. It is a distinct advantage over the competition.
  • AGM battery designs are superior because they reduce spillage that could damage the car. In addition, the fibreglass matting minimizes spills and further protects your battery and vehicle.
  • AGM batteries are made up of 99.99 per cent pure lead. It merely implies that performance and endurance will improve. By increasing the lead level in AGM, there is an extended resilience and lifespan.


AGM batteries are power cells known for their durability and efficient performance. AGM batteries are widely used as they utilize an absorbent glass technology that helps them produce more power than most batteries. In addition, the batteries use pure lead, which makes them ideal for applications requiring high energy output. AGM batteries can last between 3 to 5 years and, with proper management, can last more than that. However, with regular maintenance, some factors can affect the battery lifespan, like temperature, overcharging, sulphating, etc. Nevertheless, you can have a long-lasting AGM battery following the battery manual, saving you money.
