I hazard to suggest most places that deal primarily with car batteries simply cant test a leisure/deep discharge battery without doing it more harm than good. A prolonged low current drop test over several hours is needed not a short sharp high current one of a few seconds.
As already said Varta do some excellent medium priced leisure duty batteries as do Banner. There is a lot of budget and not so budget poor stuff out there so be wary; basic rule is lead is heavy, expensive and vital for a good battery; if it is light weight for its claimed rating it is 'light weight in every sense'. Ideally look for the protection given by one meeting EN 50342, where the capacity in AH is quoted at C20 [or K20 in some countries] a 20 hour test. Good reading is the Caravan Clubs technical article of October 2010.
Unfortunately from what you say about yours it looks to me that you are into spending money; spend it wisely.
