AGM Battery Basics 

What is an AGM battery?

In layman’s terms, an AGM battery is a battery that incorporates a glass mat separator designed to hold electrolytes. Owing to the incorporation of glass mat separators, electrolytes in AGM batteries would be kept in a suspended dry state instead of free liquid form. 

How does AMG battery work?

During operation, AGM batteries should steadily transfer electrolytes held in the separators to the plates. The amount of electrolytes on the battery separators would still stay at an adequate level in order to provide full capacity. 

Benefits of AGM battery

Output: Compared to traditional batteries, AGM batteries have rather low internal resistance so power passes through them with relative ease. As a result, AGM batteries could guarantee excellent outputs in a wide range of settings. 

Ventilation: Since AGM batteries nowadays happen to have a well-sealed construction, they never release toxic emissions into the surrounding. That means if you assemble your battery bank out of AGM batteries, there is no need to worry about ventilation. 

Maintenance: The sealed construction of AGM batteries eliminates the hassle of spilling acid in use. Hence, keeping conventional AGM batteries in top shape is just a walk in the park. 

Longevity: Thanks to its design, AGM batteries receive and deliver charge without trouble for years. In the case that your battery bank consists of quality AGM batteries, you don’t have to think about replacing it for quite some time. 

Expense: While AGM batteries seem kind of expensive, their longevity would help you save some bucks in the long run. By heading out with AGM batteries, the money that goes into battery replacements should reduce. 

Types Of AGM Batteries 

Today’s market is saturated with models but all AGM batteries could be split into two types: flat and spiral. 

Flat AGM Batteries: At first glance, the average flat AGM batteries resemble flooded acid batteries in a couple of regards. Normally, batteries of the type carry six sets of plates compressed in rows so as to put out more capacity. 

Spiral AGM Batteries: As the name suggests, spiral AGM batteries integrate spiral-wound cells that speed up the charging process. Thus, batteries of the type prove popular among those that wish to fully recharge the batteries as fast as possible.

How To Get The Best AGM Battery 

With preferences varying significantly from people to people, there is no such thing as the best AGM battery for everyone. However, in the case that you seek a good buy, it’s strongly recommended that you memorize the criteria below

VOLTAGE – Different appliances tend to run on different voltages which is why you have to pay utmost attention to voltage prior to making up your mind. The last thing you want to do is to spend money on batteries that have incompatible voltages with your appliances. Normally, you should be able to determine the voltage rating of a battery by checking out its owner’s manual. Depending on the models, it’s possible to change the voltage of battery banks by wiring the batteries in series.  

AMPERE HOUR (Ah) Commonly used to measure the amount of electricity that batteries could provide, ampere hour in essence indicates the battery capacity. To deduce the ideal ampere hour rating of your battery, it’s widely advised that you take the power consumption of your appliances into account. In the case that your appliances only require little electricity to operate, feel free to settle for standard AGM batteries. On the other hand, if you own plenty of power-hungry appliances, you have to stick to high Ah models. 

DIMENSIONS – The dimensions of the batteries that you use dictate the space that your battery bank would occupy so you should consider giving that some thoughts. Brands usually include details about dimensions in the owner’s manual but to be thorough, it’s best to read a couple of customer reviews. To avoid ending up with ill-suited models, use the measurements of the spot where you intend to set up the battery bank as guidelines. That is going to help you keep the number of batteries on your shortlist low and save lots of time. 

ENDURANCE – Overall, it’s unwise to treat battery banks roughly but you don’t need batteries that fail shortly after purchase. So unless you have the money to constantly pick up battery replacements, it’s important that you think about endurance while shopping for AGM batteries. To decide whether a battery is able to hold together over time, you need to examine and inspect its construction. If you come across issues that suggest potential compromises, just move on to other models.

When should I recharge AGM batteries?
