Anwser:Either SLA (gel cell, sealed lead acid) or AGM (absorbent glass mat) batteries can be used to power a POV. They differ in the way the electrolyte is immobilized. Gel cell batteries and AGM batteries don’t offer the same power capacity. For example, a 12 volt 36 amp hour AGM battery would be rated as 31.6 amp hours in the gel cell. Gel batteries exceed AGM in slow discharge rates and will operate in slightly higher temperature. For most intents and purposes, there is little difference between AGM and gel cell batteries. More people chose AGM because they are less expensive.
