Deep Cycle Battery
Can anyone suggest a good deep cycle battery? I've had a yellow top for the past 2 years and it's slowly dying and has been given me problems for a while after leaving my lights / radio on a few times and having to get a jump.

Aren't those things supposed to last like a decade? I would try returning it under warranty. When a basic cheap battery lasts 4-5 years I would image an Optima would last much longer...

lead-acid battery chemistry if treated badly will not last long. Even AGM technology has to be maintained above a reasonable voltage. A flooded battery if it gets under 10V is toast. AGM will recover from it once or twice, maybe . . . but if you make a habit of it, even a deep cycle battery will die young.
