What is a Standard Battery?
Definition and Basic Structure
A standard battery, often referred to as a flooded or wet-cell battery, is a conventional lead-acid battery where the electrolyte freely flows around the battery plates. This type of battery requires regular maintenance, such as topping up with distilled water.
Common Uses
Standard batteries are widely used in automotive applications, motorcycles, boats, and backup power systems. They are generally more affordable and have been a reliable power source for decades.
Key Differences
AGM vs Standard Battery Technology
Construction and Design Differences
The primary difference between AGM and standard batteries lies in their construction. AGM batteries use absorbent glass mats to hold the electrolyte, while standard batteries allow the electrolyte to flow freely. AGM batteries are sealed and maintenance-free, whereas standard batteries require periodic maintenance.
How Each Battery Type Works
AGM batteries work by absorbing the electrolyte into the glass mats, which enhances conductivity and reduces internal resistance. Standard batteries rely on the free-flowing electrolyte to facilitate the chemical reactions needed to produce electricity.
