What distinguishes an AGM battery from a conventional battery?

AGM (Absorbent Glass Mat) batteries are designed with specific features that set them apart from conventional batteries, which is why the choice highlighting their sealed and spill-proof characteristics, along with superior cold weather performance, is correct. AGM batteries utilize a fiberglass mat to absorb the electrolytes, which means they are sealed and can be installed in any position without the risk of leakage. This design not only enhances safety but also allows AGM batteries to have lower internal resistance, leading to improved performance, particularly in low-temperature conditions where conventional batteries might struggle.

In addition to these benefits, AGM batteries are also known for their ability to withstand deep discharges and rapid recharge cycles, making them ideal for use in various demanding applications, such as start-stop systems in vehicles. This combination of features makes AGM batteries a preferred choice in scenarios where reliability and efficiency are critical, especially in cold environments.
