Deep Cycle batteries
This has probably been discussed somewhere but allow me to bring it up one more time. Since deep cycle batteries are designed to be repeatedly discharged as much as 80%, does that necessarily mean ...

Uh, first the figures I saw said 50% not 80% though some claim 80% for AGM.
And Though I'm not sure of single digit discharge cycles, (Someone else suggested they are not that good an idea, I won't argue with him, I also won't agree with him, I have very simply not researched that thought well enough)
If you discharge to say 25%,,, Well you will be happy, let's just put it that way.
With nearly all batteries the deeper the discharge, the greater the damage. And the relationshiup is not linier.
That is at 25 percent you do damage, at 50 Percent you do more damage, clearly, but it is not 2x. It is greater than 2x (as in 2.y) and in the case of some starting batteries is "Many x" (how many varies brand to brand)
If you run em down 75 percent, that is perhaps 2x as bad as 50 for a deep cycle, (And many many times for a starting)
I've run my GC-2's (Deep cycle) down to .. Well I'd be embarassed to say (Lights won't) a few times over their 8.5 year life and .. Well they now need replacement... 8.5 is within the 7-10 year life expencentcy of the batteries, dead center in fact.
With starting batteries every time I've taken them that low.. NEW BATTERY TIME.
NOTE that Marine/Deep cycle, are far closer to starting batteries.
