To determine if a battery is an AGM (Absorbent Glass Mat) battery, you can check for the following characteristics.
- Label and Markings: Most AGM batteries are labeled as such. Look for labels or markings that indicate “AGM” or “Absorbent Glass Mat” on the battery case.
- Sealed Design: AGM batteries are sealed and do not have removable caps for adding water. If the battery has removable caps, it is likely a flooded lead-acid battery.
- Weight: AGM batteries tend to be heavier than standard flooded batteries of the same size because of their internal structure.
- Product Documentation: Check the battery’s product documentation or specifications sheet. This information is usually available on the manufacturer’s website or in the product manual.
- Battery Terminals: AGM batteries often have different terminal designs compared to flooded batteries. Some may have threaded terminals or specific terminal configurations.
- Price: AGM batteries are generally more expensive than traditional flooded batteries due to their advanced technology and performance benefits.
- Shape and Size: While not a definitive indicator, AGM batteries sometimes have a more rectangular, boxy shape compared to the more rounded corners of some flooded batteries.
