Do Consider These Factors: Shop For The Best AGM Battery

The AGM RV battery is much more than a power source. It becomes extremely important to select the right AGM battery for your RV or any other application that supplies the right amount of functionality, power, and reliability.

There are a few factors that should never be ignored for picking the right one.

Life Expectancy

It is potent that the battery you think to choose lasts longer and stronger. You need to assure that whether it is good for long-term use, frequent use, or any kind of use.

The more the life-expectancy the more service years will be provided to you by the AGM battery you purchase.

This is another important factor as if wrong power levels are chosen then you may encounter problems with your RV.

The battery that will deliver maximum power with output and capacity that your RV needs should be your choice. Consider these for sure:

  1. Voltage

  2. Capacity

  3. Amp hours


When you are spending money, then you need to see that the battery you choose is capable enough to support your vehicle/RV/equipment.

Amperage per hour should always be noticed. Though the AGM batteries are designed to support all sorts of vehicles and applications but still everything needs to be confirmed prior to your buying decision.

Reserve Capacity

At normal temperatures the number of minutes a fully charged battery discharges and that is referred to as reserve capacity.

The AGM batteries top in this matter as compared to the other batteries. Just match the reserve capacity that will go with your RV or application as some require more amperage and some less.

Cold Cranking Amps

In cold and freezing temperatures the ability of the power source to produce current is CCA.

The CCA of different batteries differ and if you are residing in colder climates and want a great start even if the temperatures are at the lowest then you should go for a heavy-duty AGM battery. A quality battery will always start the engine immediately and give you more pleasure.

Why Are They Better Than Wet-cell Batteries?

  • Spill-proof due to matting technology.

  • Comes with high specific power, low internal resistance, and responsiveness to load.

  • Flaunts of 5-times faster charge than the flooded technology.

  • Comes with a better cycle life than flooded systems (wet-cell batteries).

  • Sandwich construction provides vibration-resistance.

  • Great water retention: Oxygen + Hydrogen combine to produce water.

  • Stands-up well even when freezing temperatures.

Frequently Asked Question's

Q1. Are AGM Batteries A Right Choice For Your Rv?

Ans1. The AGM batteries are a far better option than the wet-cell batteries (also known as flooded batteries). Without a doubt the AGM batteries are the right choice for an RV as they are:

  • Totally sealed

  • Maintenance-free

  • Durable and safe (don’t let the user come in contact with battery acid –electrolyte).

Q2. How Much Can An Agm Battery Be Discharged?

Ans2. About 80% depth-of-discharge is offered by an AGM battery. In comparison to flooded systems, these are better as the latter is specified at 50 percent Depth of Discharge for attaining a similar life cycle.

Q3. How Long Can An Agm Battery Sit?

Ans3. In comparison to the flooded batteries generally, the AGM last 2-3 times longer. For e.g. where a flooded battery will last 3-5 years then an AGM will be like your buddy for 6-10 years. This is certainly like a cherry on top of a cake.

Q4. What Kind Of A Charger Can I Use For My AGM Battery?

Ans4. For charging an AGM battery a regular battery charger will be sufficient. Many of the gel cell or AGM batteries tend to gather information with their microprocessors to adjust the voltage and current as required. Henceforth, this is a misconception that these batteries should be charged low and slow.

Q5. What Is The Maximum Voltage-Charge Needed Fora 12-V AGM Battery?

Ans5. The charger for Deep Cycle AGM batteries should possess a mode switch for AGM type batteries. The recommendation is for a charger with a current limited to 20% or 0.2C of the battery capacity. The charging voltage should be between 14.6 – 14.8V when in deep cycle use and 13.6V – 13.8V for standby use.
