A lot of cheaper leisure batteries are just cheap normal lead plate wet acid staring batteries ...it's a bit of a topic at the moment and the Camping and Caravan Club even featured a standard people are trying to apply to cut down on this.
There is some stuff here http://www.aandncara...-technology.php that will explain it ...but my suggestion was based on the following exert ..
We set about trying to find a quality low cost battery.
We stumbled upon the newly announced, Bosch S5/Varta Silver Starter battery that was made using really advanced Technology and techniques that created not only an outstanding Starter battery but a really capable Habitation battery that would charge and recharge like no other battery before it. The technology was so advanced it was patented by the manufacturer with no other manufacturer able to copy it. The Varta incarnation cost little more than a budget Leisure battery.
We tested it to find it outperformed almost anything in the same price bracket, so began telling the World. We then got slated on the Forums because, "you can't use a Starter battery as a Leisure battery".
The reason I suggested it that is with a 5 year warranty and an 063 size you can use it to run you stuff now and then re-use it in the mini later and you can git from Eurocarparts at a good price.
