Same here, we have two Deka deep cycles and one Deka cranking battery in the boat. We bought them three years ago from a local Deka dealer (thanks for the good deal Gerald) and they are still going strong.

I think a lot of getting the most out of your batteries, especially the deep cycles, would be buying a quality battery to begin with then maintaining it properly afterwards. There are several quality brands of batteries out there and just as most other things are you will usually get what you pay for. There is no such thing as a good quality cheap battery.
