I am not sure about that type of battery? but I use a 'what some folk call a leisure or caravan battery' which requires a long trickle charge, I,m sure someone will keep me right.
But I bought 2 from Pure freedom, one for a trolly and the other for the van.
I usually charge mine once per week, depending on use, and start the charge at 6pm and switch off at 6am, (roughly 12 hours)this usually lasts me all week, and sometimes into the next week.
