I purchased a Crown Deep Cycle marine battery at Battery World last summer. Good price. Turned out to be in my opinion a piece of trash that had a good warranty if you didn't need it.
Actually the warranty was never explained to me, however Battery World was glad to take my money with a smile. Battery World now has their (Crown) battery back and my money. Make no wonder we buy China.
