In AGM batteries, the sulfuric solution is absorbed by the glass mat thus making the AGM battery virtually leak proof and much safer to use than other lead-acid batteries. Moreover, these batteries can be shipped much easier because the hazardous material transportation restrictions do not apply to the AGM batteries.
Plus, AGM battery plates can either be molded into flat plates or squeezed into cylindrical cell tubes. Furthermore, AGM batteries have been tested and found to possess a very low resistance hence these batteries are capable of delivering high currents without using too much of its internal resource.
Also, AGM batteries are considered to be very reliable despite being practically maintenance free but you would still need to change the top of the battery so as to prevent the sulphates build up. Once in use, the AGM batteries have been reported to be very low in charge thus serving much longer than other types of batteries.
AGM batteries compromise of large plates made out of lead that are submerged in an acidic electrolyte. When the vehicle is turned on and the battery starts discharging, the lead plates begin to cover in sulfate while the acidic electrolyte turns into an alkaline one.
Similarly, once the AGM battery charges, the alkaline electrolyte turns back into an acidic one because the sulfate from the lead plates goes back into the electrolyte. On the other hand, lead batteries are very likely to corrode and could be hazardous to handle as the electrolyte can cause serious skin burns if it leaks.
Plus, such batteries are not eco-friendly because if they are discarded the wrong way then they could contaminate soil and water. Furthermore, lead-acid batteries are more exposed to the vibrations of the vehicle engine thus they are much more likely to leak.

What Ratings Are Given to Batteries?
All vehicle batteries are rated on the CCA, which stands for Cold Cranking Amps, just like vehicle batteries are plus these ratings are a good indicator on how much current the AGM battery will be able to deliver when the outside temperature is around 0 degrees Fahrenheit.
However, keep in mind that this is just a rating to indicate how robust a certain battery is and not whether it will work in winter. Another type of rating is based on the size of the battery, these ratings are assigned according to the American Battery Council.
Nowadays, most batteries are assigned a rating of U1 which means that they are about 8 inches long and 5 inches wide. Such dimensions are important because different vehicles have different sized battery trays. Plus, the battery must also be connected to the battery cables thus buying the right sized battery for your vehicle is crucial.
What Are the Advantages of Agm Batteries?
The main advantage of AGM batteries is their recharging speed, with some battery models being capable of recharging almost five times faster than regular flooded version. Moreover, most AGM battery models are very compact and usually range from 35-100 Ah plus they are often used in different vehicles to power radio, windshields and mirrors.
Furthermore, AGM batteries are often used in motor and marine homes because they have great cold temperature resistance. However, AGM batteries are very sensitive to overcharging hence you will have to be very careful not to overheat or burn the battery. Also, try to keep the AGM batteries away from the engine compartment and any other hot compartments.
Why Cca Rating Matters?
The output of the battery might not be of concern to you when you have a small power needs however it will become an important factor in choosing the best AGM battery if you have a large marine vehicle with large power need. Thus, check the recommended rating of CCA that the manufacturer of your vehicle has specified. Choosing an AGM battery with very low CCA rating can lead to your vehicle not starting at all. On the other hand, a higher CCA than your vehicle can take could lead to your battery wearing out.
AGM batteries are often also called VRLA, valve regulated lead-acid battery or SLA which stands for a sealed lead acid battery. Moreover, these batteries have their own variants, for example, the gel cell battery which involves using silica dust on the electrolyte to form a thick and putty-like gel layer. Plus, because of their specific construction, these batteries can be mounted in a number of ways and do not require much maintenance.
However, they will still need some cleaning and testing for longer life. On the other hand, lead acid batteries are made out of an acid and water solution that makes up the electrolyte. This electrolyte can potentially cause chemical burns to the skin and the eyes if the battery leaks. The water from the electrolyte can evaporate during the batteries work while hydrogen and oxygen get released when the lead plates are heated.
These gases are very dangerous because they are combustible have the potential to blow up hence it is crucial for you to take all the safety precautions when dealing with lead-acid batteries. Most scientists believe that a large number of explosions occur when the electrolyte level drops thus allowing for oxygen and hydrogen to accumulate. Then when the battery is started, a spark is created that could ignite these gases.
To protect yourself, always install and connect the battery in a well-ventilated area plus never smoke around the battery. Also, think about wearing gloves and maybe even an apron when you will be handling the battery, charging or installing it. Lastly, never forget to wash your hands thoroughly after lead-acid battery handling and check for battery leaks every once in a while.
