Thanks for that information. Johnson has purchased a lot of companies that deal in sports and the outdoors.

When a regular battery the plates are just hanging there and there is a large space between each plate. There is nothing really in between the plates to secure them well.

With the optima there is a the plates are wrapped around in a cylinder shape with a fiberglass matrix between the plates. Each cell is in the shape of a cylinder and then they put six cells together. It resembles a six pack of beer if you look at it from the top view.

Deep cycle batteries regardless of brand have a life expectancy they will only be drawn down and recharged a number of time, before they start having capacity loss,....even if your charger tells you their 100% try running a load on them and see if they have the same reserve capacity that the sticker says,I'll bet not. Likewise deep cycle marine batteries are built with heavier plates to withstand the abuse they get(vibration and pounding)Optimas are built good so are Everstart marine batts. but without proper maint. none will live their expected lifetime.
