Why Should You Choose AGM (Absorbed Glass Mat) Car Batteries?
AGM car batteries contain fiberglass mats that are soaked with battery lead acid and then placed and compressed between plates of lead. This setup makes it spill-proof and allows you to install in different orientations.
The tightly packed lead plates and mats make this type of battery almost entirely resistant to vibration and shock. The tightness of the plates also reduces its risk of freezing.
AGM batteries can deliver high currents, and they can also power vehicles with high electrical demands. These types of cells also offer you a faster charge, and they are relatively lighter and cheaper than many other types of car batteries available.

AGM Batteries Vs. Gel Batteries
You may wonder, What is a AGM battery? Absorbent glass mat (AGM) technology came into the game almost 40 years ago as a sealed replacement for lead-acid batteries. They are preferred because of their spill-proof design and their lesser weight.
AGM batteries contain special fiberglass mats that absorb the sulphuric acid contained in the battery. This feature makes AGM batteries spill-proof, and also allows installation in any position without risking acid spills.
The lead plates can be placed flat in a rectangular container, or coiled into a cylinder.
In gel batteries, the acid is made into a very thick liquid using sand or silica. This technology is what makes them spill-proof and similar to AGM batteries, but that is where the similarities end.
Whereas AGM batteries are quick charging, resistant to vibration, and hold their charges, gel batteries are the exact opposite. They are delicate and prone to damage from the slightest mistake during charging.
Gel batteries also cost more than an AGM battery of similar specifications, and they can get burnt if used under heavy applications.
AGM batteries are far more durable, and they are also great in support power-consuming audio systems. It is less common to see a gel battery being used as a first choice in place of an AGM battery, and AGM batteries generally outsell gel batteries.
FAQs – Frequently Asked Questions
1. How long do AGM batteries last?
A typical AGM battery can last anywhere from three to five years. If you use it and maintain it correctly, the life expectancy can extend to eight years.
Some AGM batteries can even stay up to ten years, on rare occasions.
2. Can you jumpstart an AGM battery?
Yes, you can jumpstart an AGM battery in the case of an emergency. The battery may not charge fully because of the alternator if it has discharged completely.
However, you can probably use it for a few hours after jumpstarting.
3. Can overcharge damage an AGM battery?
Yes, it can. Always use a particular trickle battery for AGM batteries. Using a regular battery charger can cause them to get overcharged, leading to permanent damage.
4. Can you use a regular car battery Charger for AGM batteries?
No, you can’t. AGM batteries, like gel batteries, require a special trickle charger, rather than the regular chargers used for flooded batteries. You need to charge them slowly, so you need to buy a special charger to charge them fully.
