Louie the easiest way to keep a battery charged is one of those $35.00 solar chargers that supa cheap sell, leave it connected at all times and the battery will stay in great shape for years, we use these at our dark sky site and some of these battery's are 5 yrs old.
I use a 17a/hr to run my dew zappers and I get two nights out of them running the dew zappers at 3v. when the dew is heavy I have to up the voltage to 6v and then I only get one night.
cheers
David.
