How is an AGM battery different than a conventional battery?

An AGM battery uses a fiberglass mat to absorb the electrolyte that’s essential for energy storage and delivery. A conventional “flooded” battery contains a liquid electrolyte. The AGM design makes the battery spill-proof and maintenance-free.

What are the benefits of an AGM battery?

An AGM battery’s maintenance-free design makes it spill-proof and resistant to vibrations. It also offers up to twice the life of conventional flooded batteries, along with more power and Cold Cranking Amps than conventional flooded batteries.

Do I have to replace an AGM battery with another?

Yes. If the original-equipment battery was an AGM battery, it’s important to replace it with another. That also goes for “aux” batteries in vehicles with Start/Stop technology and other features with unique electrical demands.

What is an “aux” battery?

Some vehicles use an auxiliary battery as a part of a more complex electrical system with increased demands. Typically, these “aux” batteries are used in vehicles with Start/Stop technology as well as hybrid vehicles and battery-electric vehicles.

Can I use an AGM battery in a vehicle that did not originally come with one?

In most cases, the answer is yes. Most modern vehicles can accommodate an AGM battery as a direct replacement. Some vehicles, however, may have compatibility issues when it comes to the charging and voltage needs for an AGM battery.
