Sealed AGM vs. Wet Conventional Batteries and 6 Volt vs. 12 Volt Marine Batteries
Sealed AGM batteries will not leak acid and do not vent gas like the conventional batteries. They can be used in closed spaces. They typically last longer and require little to no maintenance. They do however cost more up front but in the long run save you money and time.
There once was a time when there was some merit to the claim you should use 6V batteries rather than 12V batteries. But with the advent of sealed AGM batteries we feel this is no longer the case because the layering of active material between the glass matt means there is just as much surface area available. You don't have to worry about the degradation of the plates like in the old days when it was a solid lead plate stuck down in some acid.
To get the full story behind their legend, you will have to read the article. You will discover why so many put their trust in this sealed AGM American made workhorse.
One thing we will reveal is that Lifeline's have the lowest internal resistance of any battery manufactured at only 2 percent! If that means nothing to you, know this, that number is outstanding! And when you couple that with proper wiring and charging techniques this will translate into batteries that will last many times longer than the competitors. You can learn more about perfectly balanced parallel charging on our tutorial.
So if you are searching for the best RV and Marine battery you have come to the right place! You may also want to consider updating your charging system and installing a new DLS or SDC series IOTA charger converter.
