AGM automobile batteries outperform ordinary flooded batteries in every way:

  • More durable construction
  • More starts per battery
  • Special valves protecting the battery’s lifespan
  • Safer to handle
  • Faster recharging

AGM batteries can power an engine more than 60,000 times during their lifetime. That’s more than three times the number of starts you’ll get with a standard battery.

AGMs also recharge faster than standard batteries. Starting your engine depletes your battery only a little before the alternator kicks in. When this happens, the alternator recharges the battery and keeps the car’s electrical components working.

AGMs are more resistant to tremors and vibration than standard batteries because of their absorption mats. They’re also labeled as spill-proof, which means the standards for carrying them by air or road are less stringent.

This may appear to be marketing jargon. Instead, it’s simply science.

This is How AGMs Work.

The two innovative additions to Planté’s innovation plus several minor design modifications that fundamentally increase the capabilities of automobile batteries are what give an AGM battery its superpowers.

The battery case’s valve first stops evaporating water from exiting. Perhaps you think this is the opposite of the one-way valves on coffee bean bags.

But the key to an AGM’s extended life is this simple step.

How? Read on. Lead, sulfuric acid, and water still make up its introductory chemistry. The acid molecules migrate to the lead plates when you drain power, leaving just water and lead sulfate. You are eliminating the sulfuric acid from the solution to promote a chemical interaction between the paste on the plates. When the battery is charged, this procedure is reversed.

When H2O is divided into hydrogen and oxygen gases by electricity, there is always a danger that some water may be lost. Losing those water molecules causes the electrolyte to remain more acidic than usual, which reduces the intensity of the chemical reaction that may occur on the plates and eventually reduces life.

The AGM’s valve prevents such gases from escaping

Except when the battery is overcharged. When an AGM is charged using the incorrect charger, the electricity must travel through everything it can. That implies splitting up more water molecules and accumulating excessive gas inside. When this happens, the safety mechanism kicks in, discharging some gas to relieve the pressure inside the battery.

Second, there are fiberglass mesh mats. They serve as the general manager of AGM (absorbed glass mat) batteries.

The electrolyte (water and sulfuric acid) is absorbed by ultra-thin glass fibers, which form thin pillows that cushion the lead plates. Instead of the free-flowing liquid inside a standard automobile battery, the AGM stores its charge in saturated sponges covering the lead plates. The total coverage of the glass mats makes it easier to draw more power from an AGM battery – and to recharge it. AGM batteries outperform ordinary batteries in terms of power, speed, longevity, and durability.
