Introduction

Are you wondering how long AGM Car Batteries can last? While many expect them to last forever, there are a few key factors that determine their true lifespan. In this article, we’ll discuss the typical lifespan of AGM batteries, the factors that influence it, and what you can do to extend their life.

 

What Are AGM Car Batteries?

How Do AGM Car Batteries Work?

AGM batteries use a special technology where the electrolyte (battery acid) is absorbed into fiberglass mats, preventing any spillage. This design ensures that the battery remains sealed, making it safe to use in various applications. The electrolyte doesn’t move freely inside the battery, which also helps reduce gas emissions during charging.

● Electrolyte in Fiberglass Mats: This technology immobilizes the electrolyte, preventing leaks.

● Sealed & Spill-proof: Prevents accidents, ideal for vehicles and equipment.

● Oxygen Recombination: Reduces the need for frequent water topping up by reusing oxygen inside the battery.

AGM batteries are a great choice for vehicles with start-stop systems, as they are more efficient in providing quick, repeated bursts of power without losing capacity.
