AGM vs Flooded Batteries: Which Lasts Longer?

Understanding AGM and Flooded Battery Technology

When it comes to batteries, there are two main types: AGM (Absorbent Glass Mat) and flooded. Both types have their own advantages and disadvantages, but which one lasts longer? Let's take a closer look at these two technologies to determine which is the right choice for your application.

AGM Batteries

AGM batteries use a special glass mat material to absorb the electrolyte, which makes them maintenance-free. This also means that they can be mounted in any orientation, making them ideal for tight spaces. AGM batteries typically have a longer lifespan than flooded batteries, lasting up to 10 years with proper maintenance.

Flooded Batteries

Flooded batteries are the most commonly used type of battery on the market today. They use a liquid electrolyte, which makes them heavier and more prone to leaks. Flooded batteries require regular maintenance, including checking the electrolyte level and adding water as needed. Flooded batteries typically have a shorter lifespan than AGM batteries, lasting around 5 years with proper maintenance.

Which Lasts Longer?

In general, AGM batteries last longer than flooded batteries. This is due to the fact that AGM batteries use a sealed design that prevents the electrolyte from leaking out. As a result, AGM batteries are less likely to suffer from corrosion and other problems that can shorten their lifespan.

Deciding Which Battery is Right for You

The best way to decide which type of battery is right for you is to consider your specific needs. If you need a battery that is maintenance-free and can be mounted in any orientation, then an AGM battery is a good choice. If you are looking for a more affordable option, then a flooded battery may be a better choice.
