140Ah AGM Battery

To get the most out of your 140ah agm battery, you need to know exactly what an AGM battery is and what it can do. AGM technology stands for Absorbent Glass Mat. That explanation alone sounds ridiculous but wait. The absorbent glass mat refers to a fine fiberglass mat that is capable of absorbing sulfuric acid, making batteries spill-proof. Makes more sense now right? In the 1980s the demand was increasing for lighter weight and less hazardous batteries that could be used in aircraft and vehicles. Read more

To get the most out of your 140ah agm battery, you need to know exactly what an AGM battery is and what it can do. AGM technology stands for Absorbent Glass Mat. That explanation alone sounds ridiculous but wait. The absorbent glass mat refers to a fine fiberglass mat that is capable of absorbing sulfuric acid, making batteries spill-proof. Makes more sense now right? In the 1980s the demand was increasing for lighter weight and less hazardous batteries that could be used in aircraft and vehicles.

AGM technology allowed this demand to be met. All of a sudden batteries could be transported without hazardous material issues and the construction of the mat meant that batteries could now be shaped as a cylinder or the traditional rectangular cube.

The inside of a battery contains positive and negative lead and lead oxide plates that attract or release electrons when they react with an electrolyte typically made of sulfuric acid and water. AGM batteries hold and suspend the electrolyte mixture like a sponge with tiny glass fibers while maintaining evenly distributed contact with the active lead materials on the plates. The electrons flow in a series circuit through six cells, each of which runs at approximately 2 volts for a total of 12 volts.

AGM batteries improve on a major flaw of flooded batteries, spillage, but they are not without their own negatives.

Pros

Sealed and maintenance-free
No spillage
Claimed not to degrade
Claimed not to sulfate or corrode
Claimed shock resistance
Claimed better discharging and recharging efficiency
Claimed higher starting power

Cons

Sensitive to overcharging and undercharging
Reduced charging capacity over time
Typically higher price tag

AGM batteries could last two to three times longer than traditional flooded lead-acid batteries. Traditional batteries should typically be replaced every three to five years, depending on a range of factors such as driving environment, driving conditions, and driving habits.

What’s the Difference Between a Regular Battery and an AGM Battery?

The primary difference between the two is the state of the electrolyte. In traditional flooded lead-acid batteries, the electrolyte fluid is free-flowing and can spill. In AGM batteries, the electrolyte is suspended and held within a glass material.

What’s the Difference Between an AGM Battery and a Gel Battery?

Gel batteries use a different method to keep the electrolyte in place. Gel batteries typically use a chemical agent such as silica to create a gel-like substance that allows for less movement. Both gel and AGM batteries are considered Valve-Regulated Lead-Acid (VRLA) batteries.

Can You Use a Regular Battery Charger On an AGM Battery?

Because AGM batteries are sensitive to charging, we recommend buying a charger and maintainer specifically designed for AGM batteries.

Does a New AGM Battery Need To Be Charged?

No, new batteries come ready to go!

Tips for Changing an AGM Battery

Wear paint-friendly clothing, meaning clothing without any hard items such as buttons, zippers, or fasteners. When you’re leaning over to pick up that heavy battery, you could scratch the paint.

Never let anything metal such as a tool touch both battery terminals at the same time. This closes the battery circuit and will result in sparks.

If all of this is too overwhelming, chain auto parts stores such as AutoZone and Advanced Auto Parts offer free battery testing and charging services.
