Which batteries are a better value,
Gel or AGM?

The Gel technology has far superior cycling ability. At the typical 80% discharge rate (80% of the battery capacity used) the gel battery will last 300% longer than the AGM battery!!

Typical* VRLA Battery Cycling Ability
vs. Depth of Discharge
Typical Life Cycles

Capacity Withdrawn	Gel	AGM
100%	450	150
80%	600	200
50%	1000	370
25%	2100	925
10%	5700	3100

* You may experience longer or shorter life based upon application, charging regimen, temperature, rest periods, type of equipment, age of battery, etc.
