How Long Does an AGM Battery Last?

Chances are, you don't think about your vehicle battery until your vehicle doesn't start. But rather than continuing to invest in the same traditional flooded batteries, let's take a step back and consider another great option — Absorbed Glass Mat (AGM) batteries.

AGM batteries go their start in the early 1980s as a sealed lead-acid battery for military aircraft and UPS to improve battery reliability and reduce vehicle weight. Since then, AGM batteries have become popular choices for commercial, marine, and powersports vehicles to get the best of enormous cranking power and deep cycle reserve power. Sounds, great, right? But one important thing to consider when shopping for a new battery is — how long does it last?

So How Long Do AGM Batteries Last?

AGM life expectancy is a commonly asked question in the industry, and for good reason. The goal of buying any vehicle part is to make sure it lasts a long time, but not all vehicle batteries are created equally when it comes to lifespan. Traditional flooded lead-acid batteries are typically not robust enough for repeated cycling and tend to experience sharp capacity fade after about two years with an overall service life of about five years.

AGM batteries such as Odyssey Performance and Extreme Series batteries not only feature an overall service life of 3-10 years, but they also feature a storage life of two years before requiring a recharge. For a traditional battery, storage life is only as much as 6-12 weeks.
