Buying Guide

What Is an AGM Battery?

An Absorbent Glass Mat or AGM battery is a lead-acid battery that provides power to vehicles that have high electric demands. The sulfuric acid inside the battery is absorbed by a fine fiberglass mat that separates the positive and negative plates.

The battery acid is held inside the unit by the fiberglass mat. The body prevents the acid from flowing within the battery. The plates are compressed in each cell, while the plastic case holds the plates under pressure. The compression prevents plate materials from breaking apart.

The compression also reduces internal resistance. The design allows more pulse power to move out from the battery, thus charging up various electric devices. The full protection also allows the battery to last longer.

A relief vent also appears in an AGM battery. The vent releases pressures produced by gas. The gas comes out during charging, although the total amount isn’t too substantial. The vales in the battery also open at low pressure. The features will close to keep air from leaking into the battery.

What Items Can Use an AGM Battery?

You can get an AGM battery ready for many devices, including:

  • Start-stop vehicles
  • Trolling motors for boats
  • Motorcycles
  • Golf carts, scooters, and other small electric vehicles
  • Vehicle audio systems
  • Portable media systems
  • Heated seats
  • Assorted camping items

Some planes and helicopters in the military use AGM batteries as well. The easy to use design makes them ideal for such occasions.

How to Choose the Best AGM Battery

There are multiple things to consider when looking at how well an AGM battery can work. These include the following:

Weight

Look at the weight of your AGM battery, especially if you’re trying to power something small. AGM batteries are lightweight in comparison with other models. But you should still ensure your battery isn’t overly heavy.

Design

Your AGM battery should feature a rectangular look similar to what you’d find in a traditional car battery. The shape is perfect for when you have a smaller item to charge.

Voltage

Most AGM batteries operate on 12 volts. The total should be good enough for most devices, but you must ensure your battery is easy to charge.

mAh Total

The mAh total refers to the milliamp hours that a battery can produce. The measurement entails the electric power that works. A higher mAh total means that the battery has a higher capacity. You’ll need a good enough capacity for whatever you wish to power, although the rate at which you’d burn through it before having to recharge the battery will vary based on how you use the unit.

Sensitivity

Your battery should be capable of handling various temperature extremes and vibrations. A good rule of thumb is to avoid using a battery in certain extremes, although an AGM battery will work through more conditions.

Lead Type

You might come across either a recycled or virgin lead. The lead may be designed with a recycled body, but it may not support as many cycles or recharges as a virgin lead. The virgin option is a new one that has not experienced any cycles or recharges before you use it for the first time.

Advantages of AGM Batteries

  • An AGM battery charges faster than a traditional lead-acid flooded battery.
  • The battery works well in freezing conditions. It will not struggle to start when it is cold.
  • The compact construction ensures the battery won’t experience lots of vibrations. It will not be harmed by external vibrations.
  • The battery has a higher specific power level and low internal resistance.
  • The body will not leak or spill, thus reducing maintenance needs.
  • The battery lasts longer than regular flooded batteries.
  • The self-discharge rate is low. The rate is about 1 to 3 percent each month.

Disadvantages of AGM Batteries

  • The battery requires a higher investment at the start.
  • You must watch how you charge the battery. You could harm the battery if you charge it for too long.
  • The battery’s capacity may decline over time, although this is a common issue among batteries that focus on electric items.
  • Excess heat can damage the battery. The power source must be away from a motor, engine, or other forms of heat. You’d also have to stop charging the battery if the core reaches 120 degrees Fahrenheit or 49 degrees Celsius.

Conclusion

It is outstanding to see how an AGM battery works. An AGM battery can work in many conditions, not to mention it can last for a while. You’ll appreciate how such a battery is easy to maintain and use in many situations. The general functionality of the battery makes it an ideal option for your use.

Recommendation

Considering above all the factors (Specs & Pricing), VMAX MR 127  grabs top position in the list of best AGM marine batteries. The battery does well for many heavy-duty needs, and it can also recharge in moments. The design is also sturdy, as it produces enough energy for many power uses without delay.
