Best AGM Battery in 2022: Capacity, Deep Cycle Power, Reserve Capacity, Voltage, CCA, etc.

In the early 1970s, multiple investigations in the field of efficient and safe battery technologies led to the development of an AGM (Absorbent Glass Mat) system. AGM batteries contain acid in the ultra-thin glass mats, unlike the conventional flooded lead-acid batteries. Nowadays, AGM technology is widely used for modern cars and all-terrain vehicles due to the design peculiarities of such batteries. Let’s have a closer view of advanced AGM products and the best options available on the current market.

What is the best AGM battery? The high-performance deep cycle AGM battery should be suitable for the majority of modern types of vehicles, marine motors, and RVs. Due to its innovative Absorbent Mat Technology, it can store an unmatched amount of energy to power various electric devices during extended periods of time. Thanks to the minimum self-discharge rate it should be a perfect solution for all-season applications. More than that, such a battery is considered to be a leak- and maintenance-free which makes it the best user-friendly option among other modern battery technologies.

What is AGM technology? | Advantages over SLA batteries

AGM batteries, together with gel cell batteries, are the modern types of valve-regulated lead-acid (VRLA) batteries which are also named as sealed lead-acid (SLA) batteries.

AGM and gel batteries are similar in design developed to provide a sufficient sealing of housing with internal lead plates submerged in electrolyte material of higher density. Unlike gel batteries with their gelly-type electrolyte, AGM batteries feature an ultra-thin glass fiber in-between the plates saturated with liquid electrolyte. Due to the absence of flooded electrolytes in AGM batteries and their high-tightness characteristics, the risk of leakages is minimized. Thus, such batteries can be used at a certain slant, and they are safe in case of an occasional tip over. Besides, such batteries are suitable for almost any type of vehicle.

• AGM self-discharge rate is considerably lower (1-3% per month) in comparison with conventional flooded lead-acid batteries. That is, they can be stored for a year without additional recharging before its further use.
• AGM batteries feature deep cycle capabilities. That is, they can be discharged down to 50% without affecting the installed capacity. Besides, they are less sensitive to temperature fluctuations with an ability to work within – 40 F° to 158 F°. And again, it relates to the fact that there is no free liquid acid inside which could be frozen and expanded.
• AGM batteries are maintenance-free except for minor cleanup from dust or dirt which can be gradually accumulated with time. With a rugged and sealed design AGM batteries are highly resistant to vibrations and impact loads.

More than that, AGM batteries come with lower inner resistance than the traditional models. Thanks to this feature they can generate higher current in a shorter period of time, which is especially important during cold cranking.

Fields of application of AGM batteries

AGM batteries are capable of generating a high starting current rate and a quick charge recovery. Besides, these batteries are widely used in high-class vehicles to power big energy-consuming accessories like heating and audio systems.

For instance, the OPTIMA DH6 YELLOWTOP BATTERY is designated for heavy-duty vehicles and capable of supporting an entire range of high-demanding onboard electronics.

The development of modern battery technologies has contributed to the dissemination of professional-grade solutions to residential fields of application. The market of a backup power supply is not excluded. In particular, maintenance-free high capacity AGM batteries can be applied as follows:

• UPS (uninterrupted power supply) devices, for domestic and commercial applications, including deep cycle usage. The INTERTSATE DCM0100 would take the lead with its superior deep cycle power.

• Marine motors, RV, off-grid applications and fish finders. You would appreciate the RENOGY 12 VOLT 100AH DEEP CYCLE AGM BATTERY as a reliable backup energy source.

• Solar energy storing. The kit of RENOGY DEEP CYCLE AGM BATTERY & MONOCRYSTALLINE SOLAR PANEL would be an outstanding combination for such purposes.

• Auto and motorcycle racing companies stand for AGM products due to their ability to withstand higher vibrations and higher impact loads in comparison with the conventional lead-acid models. In particular, the ODYSSEY PC680 battery is specifically designed for power sport applications.

Features to be considered when looking for AGM battery| Buyers’ Guide

Capacity. It is one of the main parameters which should be obligatory to consider when choosing an AGM battery. It is a volume of electricity stored by the battery and the amount of time it is capable to power your vehicle and other energy consumers. The capacity of AGM products is usually measured in Ah. It is preferable that the amount of power left after starting would be sufficiently high, as this might guarantee a successful restarting in case of failure. And be advised that, high capacity batteries take more time for recharging. Renogy has 12 Volt 100AH & 200AH Deep Cycle AGM Batteries.

Reserve capacity. It is another crucial issue you should think through before purchasing an AGM battery. Reserve capacity shows how much time (minutes) left till full battery depletion at an average ambient temperature. AGM batteries demonstrate quite a high reserve capacity in comparison with conventional flooded lead-acid options. Thus, AGM products have on average 100 minutes of reserve capacity and even more.

Voltage. This parameter helps to monitor and determine battery charge. By applying special measuring devices you can easily get to know a state of charge, thus increasing a useful lifetime without affecting battery capacity. A conventional ideal voltage level should be always close to 12,8V. However, don’t forget that this value will be lower with outside temperature reduction, and vice versa.

Cold Cranking Amps. This definition means the maximum current transferred by a battery during several seconds for engine starting. If a battery doesn’t come with appropriate CCA for a certain state or a region with specific weather conditions, there could be mishaps with its smooth performance in winter. 800 CCA and higher would be adequate values for those who live in colder areas. Renogy Deep Cycle AGM Battery for RV, Solar Marine and Off-grid Applications has the highest rate of 1800 CCA in the class.

Overall dimensions. Additionally, you should pay attention to the size and weight of an AGM battery. Despite the fact that there is no direct relation between battery size and its properties, it just could happen that the battery will not fit its mounting place.

Weight. You might need to know the weight of a battery in case you are going to transfer it from its working stationary place to another. For instance, if you plan to use it as a UPC source, or as solar energy storing battery, then its portability would be highly useful. Besides, knowing the weight of a battery, you can figure out which tools and attachments will be required to carry it safely.

How to charge AGM batteries?

Be advised that in order to charge such batteries you will need special devices designed for dealing with AGM batteries only, or universal chargers with an additional option that makes them compatible with AGM systems. It would be an ideal situation if you purchase a battery together with the right charger. Otherwise, using an improper device you might overcharge your battery, which is highly sensitive to excess voltages. Thus, if you want to purchase a universal device that could be used as an AGM battery charger and portable power station for other electronics or appliances, check its compatibility beforehand.

For instance, the DEWALT DXAEJ14 is a universal helper, indeed. It can be used as a jump-starter for 12V AGM, GEL and WET batteries. Besides, it has an alternator check function, and it is equipped with an auto-stop 120 PSI air compressor. More than that, it can simultaneously support two sensitive electronic devices by means of its USB outlets provided.
