Qu'est-ce qu'une batterie AGM ?
An AGM (Absorbent Glass Mat) battery is a type of sealed lead-acid battery that uses a highly absorbent fiberglass mat to hold the electrolyte. This design allows for a maintenance-free, spill-proof, and vibration-resistant battery that delivers high cranking power and deep cycling capabilities. AGM batteries are widely used in start-stop vehicles, marine applications, solar energy storage, and backup power systems due to their reliability and enhanced performance.
AGM Battery vs. Standard Lead-Acid Battery
Compared to conventional flooded lead-acid batteries, AGM batteries offer several advantages:
-
Maintenance-free – No need to add water or perform routine maintenance.
-
Higher power output – Provides stronger and more consistent cranking power for vehicle startups.
-
Faster recharge rate – Recharges up to five times faster than standard batteries.
-
Better deep cycling performance – Ideal for applications requiring repeated discharge and recharge cycles.
-
Improved vibration resistance – More durable for off-road and high-performance vehicles.
-
Longer lifespan – Typically lasts longer than traditional flooded lead-acid batteries.
AGM Battery vs. Lithium Battery – Which is Better?
While lithium batteries are becoming increasingly popular, AGM batteries remain a preferred choice for many applications. Here’s a comparison:
