12V Lead-Acid vs 12V AGM Battery
First, let''s define what these batteries are. A 12V battery is a lead-acid battery that is commonly used to power vehicles and boats. It has a nominal voltage of 12 volts and is rechargeable. On the other hand, a 12V AGM battery is also a lead-acid battery, but it uses Absorbed Glass Mat (AGM) technology to hold the electrolyte in place.
