Is there an advantage to the AGM style battery over the regular wet cell? Looks like I can get a regular wet cell battery (size 24, 650 CCA) for $100 - $150, and an AGM style with the same specs for $150 - $200. Is the AGM technology worth the extra cost? I don't have a lot of electronics nor any add on lights to power and live in a fairly temperate climate (Kentucky).
