If you are keenly interested to know about the AGM batteries that are new in the market. So you have an approach to the right place.
One of the most common questions asked by people is, " how do I know if my battery is AGM" and what does it mean. So the AGM batteries are the advanced lead-acid batteries designed, including technologies like gel and liquid lead-acid. These batteries provide superior power to support high electrical devices or start-stop technologies.
Let’s deep dive -
Absorbed Glass Mat batteries are built differently than conventional flooded batteries. This write-up mainly covers AGM means on battery or why they are more convenient than old traditional batteries.
A thin ultra-fine fiberglass mat is wedged between the plates in AGM batteries (also called starved electrolyte), which are saturated with battery acid to about 95 percent of what they can hold. This mat is then packed into between the plates and compressed slightly, then welded/soldered in place. They are almost immune to vibration because the plates and mats are packed reasonably tight.
What exactly the AGM battery means and how it benefits:-
?Steady life up to 2x longer than standard flooded batteries
?Intended for harsh weather conditions and demanding conditions
?Controls high electric charges
?Charges up quickly and extends cycle life
?Perfect for applications on start-stop
?Vibration resistance
?Nonreplaceable and maintenance-free
?Greater flexibility in mounting
It is important to know the type of battery you currently have at hand because each type has different handling procedures. The most popular lead-acid batteries type include liquid lead acid or wet cells. But AGM batteries are the newest in the market and usually referred to as dry cell batteries, which can be replaced by the wet cell batteries. These batteries have a reputation for being safer, more mobile, and longer-lasting.
Below are the two methods to determine the type of battery:-
First method: It involves studying the label on the battery. The terms on liquid batteries or flood-lead-acid batteries you will find include "wet cell," "lead-acid," or "flooded lead acid," and "liquid lead acid." Now, Gel-filled lead-acid type batteries will have "Gel-Filled" written on the label.
And then the labels of the AGM lead-acid batteries should state "AGM" or, in full words, "Absorbed Glass Mat," or terms such as: "dry cell," or "sealed regulated valve," or "non-spill," or "regulated valve" on the label.
However, telling an AGM apart from a gel cell is difficult if there is no labeling. Still, if doubtful, you can turn to online lookup details using the battery model number. The manufacturer's information and the name or number of their model are usually embossed on the case or placed on the label.
Second method: You have to look at the top of the battery. Usually, batteries have removable tops or caps unless you find "sealed" written on the label if they are liquid lead-acid type. Gel-filled type and AGM lead-acid batteries are designed with flat tops from which the positive and negative endpoints emerge.
You need to get a safety protocol (goggles and rubber gloves) in this method because you need to shake the battery. You'll feel the type of liquid lead-acid battery has a wiggle after it's heavily shaken.
The liquid center generally continues to move for a while, even if the battery is sealed. It is exactly the opposite. If they are a gel-filled battery or an AGM lead-acid battery, they won't wiggle after the shaking.
Changing of batteries is now a way more complex feat than what it was 20 years ago with conventional lead-acid batteries. Apparently, it is one of the reasons why a professional workshop should carry out the replacement. These days, only 58 percent of the batteries are present in the engine compartment. However, 40 percent are in the trunk, while 2 percent are installed in the passenger compartment. For some car models, seats may need to be removed or carpets cut in order to reach the location where the battery is placed.
Replacing a modern battery can take up 28 steps, which significantly complicates the entire process. Individuals must understand that incorrect replacement of the battery can cause severe malfunctions. A DIY installation that is not carried out precisely can cause restriction or even failure in the start-stop function, which can further result in increased fuel consumption. Therefore, the experts in a workshop are apprised with the current battery technology. However, if you are still bent on changing your own AGM, note that an AGM battery is always replaced with an AGM, while an EFB battery can be replaced with either an AGM or EFB.
AGM batteries eliminate acid spillage in accidents because they are sealed. If your car’s battery is not under the hood, the probability is that it is an absorbent glass mat (AGM) or a gel cell battery.
Individuals must comprehend a few prevalent misconceptions about AGM batteries while they are undertaking a replacement. While the installation process of an AGM or a conventional battery is the same, during replacement, additional recalibration steps need to be conducted to prevent battery failure. Newer vehicle models entail a Battery Sensor Module that requires a scan if the battery is being replaced. However, if the system is not recalibrated accurately, the chances are that the alternator might overcharge the battery and cause the battery to fail post replacement.
Since AGM batteries are sealed and cannot be topped easily, they cannot be replaced by a standard lead-acid battery. AGM cells require a slightly different charge rate to prevent any overcharging. In the event of excessive discharge, the safety valves provided in the battery will open and release some amount of the electrolyte into the atmosphere. Overcharging of the battery can cause the cells to dry out prematurely. Therefore, experts recommend that the entire replacement process of AGM batteries must occur under expert supervision.
