In recent times, technological advancements have brought about significant innovations, leading to the development of more efficient and long-lasting products compared to their traditional counterparts. The AGM (Absorbed Glass Mat) battery, introduced in the early 80s, emerged as an enhanced alternative to the flooded lead-acid battery, known for its durability and minimal maintenance requirements, without any risk of spillage.

Conversely, the flooded lead-acid battery, a stalwart in use for over a century and a half, relies on liquid electrolytes and is often referred to as a wet cell battery. While it has served various applications, the advent of AGM technology has provided a viable alternative.

Here are key distinctions between an AGM battery and a lead-acid battery:

Maintenance Needs:

  • Lead-acid batteries require well-ventilated spaces due to the emission of gases from the electrolyte. In contrast, AGM batteries are maintenance-free and emit no gases, making them suitable for vehicles with batteries in enclosed areas like trunks and beneath seats.

Durability:

  • Lead-acid batteries are susceptible to damage from vibrations and forceful movements, requiring careful mounting to minimize potential harm. AGM batteries, constructed with glass mats and robust battery plates, boast an unbreakable structure, enhancing resistance to shock and vibration.

Internal Resistance and Power Output:

  • AGM batteries exhibit low internal resistance (around two percent), resulting in higher power voltage. Flooded lead-acid batteries, with internal resistance ranging from ten to fifteen percent, fall behind AGM batteries in power output.

Charging Time:

Lifespan and Self-Discharge:

  • AGM batteries showcase a lower self-discharge rate, ensuring a longer lifespan of up to seven years with proper maintenance. In contrast, other batteries, including flooded lead-acid types, typically last three to five years.

Summary

  • The advancements embodied in AGM batteries present a multitude of benefits compared to the historical usage of a singular brand of batteries. Consequently, opting for AGM batteries, given their superior attributes, is highly recommended over traditional lead-acid batteries.
