Battery help. I searched but that didn't help.

75' to the shed?  It'd be pretty easy to bury a line and get an outlet out in your shed to take care of the extension cord/wife problem (unless you have a mountain of concrete or landscaping in the way).

Big trees=big roots and lots of concrete but It can be done. Bigger issue is a full and outdated breaker box. That needs to be replaced before we add new circuits. We want to add a spa to an already existing pad but can't until we replace breaker box.

If na extension cord can be run to them, Id string one out to a charger once a month before I went through the trouble of hauling out/in batteries. A charged batter will weather the winter just fine. 

I just replaced the batteries another set of group 24s from Costco so i could get out on the water today. All symptoms of low voltage went away and boat ran/started perfect.  I ordered a charger and will use an extension cord periodically. Will prolly add an ACR and wire it up when I install the charger, prolly after i install my reversible bow pump stuff which has been sitting in a box in my garage since Christmas. Next set of batteries will be 1 house 1 starter.
