Ugh, I hate "which battery" threads cz they are always so full of whack. You buy batteries by weight and weight alone (for the given group size). CCA and amp hours mean nothing in terms of longevity. Lead does. More lead, more life. Period.
The best quality batteries are in no particular order; Odyssey, Trojan, Deka, and Surette/Rolls. These are all made in the USA or Canada in ISO9001 certified facilities.
There are two types of battery. Starting batteries, and deep cycle. Starting batteries will be a lot lighter in weight as they have open mesh plates to give more surface area. That allows lots of electrons to flow. Think of this type of battery as a sprinter. Deep cycle has flat plates which release electrons more slowly, they also can take a deeper discharge before they begin sulfation. They are like a marathoner.
Batteries may use an electrolytic solution (flooded) gel or absorbed glass mat (AGM). The gel and AGM batteries never need topping up and can be stood on end or on their side as there is no sloshing inside the battery case. They also tend to last longer.
The best way to ensure long battery life is to buy the biggest heaviest battery that will fit. That way you discharge it less. Also keep it charged. If it goes flat sulfation can occur and that will kill it.
So take your pick; starting or deep. You can start an engine with a deep cell, but you can't run a start battery as long as a deep cell. I use a Deka Marine Master AGM deep cycle in my DK45. Has been in there 5 years still going strong.
