Read this & look at the #35 Footnote (listed in all three sizes of Deep Cycle Marine batteries) which says :

"Deduct 15% from CCA and CA rating to allow for double insulation (glass mat)"

And right under the Deep Cycle list is this : Note: “DC” (deep cycle) part numbers include double insulated glass mat separators.

So are they saying that the CCA & CA ratings on the chart are 15% over their actual value ??

Yeah, I believe you are right, you deduct 15% from the CCA and MCA due to the double insulated glass mat separators. That sure is an odd way of presenting the data.

Just blows my mind how these battery companies all play these games. Companies like Johnson Controls won't even put out a chart like this, probably on purpose just to keep everyone clueless of what their stuff is actually rated at.

Is it possible to have a battery for trolling motor 12 volt that is not heavy. Is it a general rule that a heavy battery has more reserve than a lighter deep cycle? Any recommendations on a battery just for trolling, trying to stay under 200.00. Trying to lighten the boat a little
The battery I have been using is 60 lbs.
675mca
550cca
182rc
105ah@20hr
If I replace this battery would I simply do the math and buy the best battery for the buck.
Going back to how do they test their battery

The heaviest battery will have the largest capacity unless you move to another technology. Lithium batteries are substantially lighter than lead acid batteries.

Thanks, I will keep reading the post here and learn more about batterys.
