AGM stands for absorbed glass mat, which means the battery acid inside is absorbed into fiberglass mats instead of sitting as a free-flowing liquid. The fiberglass mats spread more electrolyte in contact with the ultra-thin lead plates while cushioning the battery against knocks, bumps, and vibrations. Because of the absorbent glass mats, battery makers can squeeze in more lead plates. More lead in the battery means more power is available.AGM batteries were originally developed in the 1970s for telephone boxes and computer rooms (back when a computer took an entire room).
Comparison
Here is a brief comparison of the two best AGM batteries.

AGM Deep Cycle Battery |
| An AGM golf cart battery is a type of deep cycle battery that uses Absorbent Glass Mat (AGM) technology. These batteries are specifically designed to provide long-lasting, consistent power for electric golf carts and other similar applications. AGM batteries are a subtype of lead-acid batteries, but they differ from traditional flooded lead-acid batteries in their construction and performance characteristics. | These batteries are designed for deep discharge. This includes flooding, AGM, and gel types. Deep Cycle Batteries, or ‘*solar batteries store energy in RE systems. To use electricity outside of production times, you’ll need batteries. For instance, batteries are vital if your solar array generates excess power on a sunny day. They let you access that power after sunset. They won’t work during a grid outage. To ensure power availability, you need batteries. But which ones? First, identify the type of battery required. |
| Maintenance-Free
No need to add water or check electrolyte levels. |
Maintenance-Free
No need for water refills or regular upkeep. |
| Quality
Lithium batteries have several advantages, making them a great option for golf cart owners. Before comparing lithium battery options, define your golf cart’s requirements. Maintenance-Free Convenient AGM battery seals, unlike traditional flooded lead-acid batteries. Thus, they don’t need regular maintenance, such as water checks or additions. This convenience saves time and effort, allowing you to focus on other priorities. |
Quality
AGM Deep Cycle Batteries are known for their durability and maintenance-free operation. They offer reliable deep discharge cycles and are highly resistant to vibration, making them ideal for marine, RV, and off-grid applications. With a sealed design, they prevent leaks and spills, ensuring safety and consistent performance. |

Fast Charging:
Efficient charging times, supporting quick recovery. |
| Fast Charging:
Supports quicker recharging compared to other battery types. |
Low Self-Discharge
: Retains charge when not in use for longer periods. |
| Technology
The AGM Golf Cart Battery uses Absorbent Glass Mat (AGM) technology. It absorbs the electrolyte in fiberglass mats to make the battery spill-proof. |
Technology
Deep Cycle Battery batteries are designed for deep discharge. This includes flooding, AGM, and gel types. |
| Usability
AGM Golf Cart Battery: Engineered for golf carts, providing a consistent energy supply. |
Usability
Deep-cycle batteries are used in many applications, including solar power systems, marine use, RVs, off-grid setups, and golf carts. |
| Cost
AGM Golf Cart Battery: It’s pricier than flooded lead-acid batteries but cheaper than lithium-ion ones. |
Cost
Deep Cycle Battery: Flooded batteries are usually cheaper than AGM and gel types. They share a comparable price point with AGM golf cart batteries. |
| Lifespan
AGM golf cart batteries outlast flooded lead-acid batteries in similar conditions. Correct charging and complete draining increase battery duration.
|
Lifespan
Deep cycle batteries usually last less time. AGM and gel deep cycle batteries can match or exceed flooded AGM golf cart batteries in lifespan. |
| Weight
AGM Golf Cart Battery: Lighter than flooded deep-cycle batteries because it’s sealed. |
Weight
Flooded batteries are heavier. AGM and gel versions match the weight of AGM golf cart batteries.
|
| Temperature Tolerance:
AGM Golf Cart Battery: Works better in cold than flooded batteries. |
Temperature Tolerance
Deep Cycle Battery: Flooded batteries struggle with extreme temperatures. AGM and gel types match the AGM golf cart battery’s resilience. |
FAQs
Is AGM golf card battery good for golf carts?
AGM Golf batteries can power energy-intensive accessories. You can build them to fit various sizes. This is why this technology is ideal for high-performance EV golf carts.
How long should AGM golf cart batteries last?
Deep discharges shorten battery life and reliability. AGM batteries have a lifespan of 3 to 7 years. Yet, in ideal conditions, they can exceed a decade. Extreme heat and complete draining can cause early failures.
Do AGM batteries need a special charging system?
AGM batteries have special charging needs. Some battery chargers have an AGM or Absorbed setting for special needs.
What happens if you charge an AGM battery with a normal charger?
Chargers differ in power. Most 12-volt automatic chargers work with AGM batteries but only charge them to 80%. Newer models have special settings for AGM batteries.
What type of battery is best for an electric golf cart?
Golfers require a good golf cart to maintain consistent power and speed on any course terrain. Lithium batteries can manage this.
What is the disadvantage of AGM batteries?
The main disadvantage of an AGM battery is its high cost, compared to a flooded lead-acid battery.
What is the difference between an AGM and a regular battery?
AGM batteries recharge faster than regular ones. They have low internal resistance, allowing more amps while charging. In contrast, standard batteries, with higher resistance, must have more voltage to recharge.
