I have to replace my two 12v coach batteries. Again. I am going to get the maintenance free ones because I can't see to add water to the back battery. I tried the battery watering system. I think the shut off valves don't work. Acid has slopped all over. I understand the Optima maintenance free ones are more expensive than the regular Group 27s that I have now, and at least one person said they aren't as powerful. Since I boondock approximately two days per year, this should not be a problem. I don't even use the furnace, which is the main 12v draw in my mh. I've killed too many pairs of batteries. If these die an early death, then I'll have a better indication that something in my coach is reducing normal battery life. I have a new converter, so at least these won't be subjected to the old defective one.
I believe that 4 years and at least as many pairs of batteries has proved that I have tried the maintenance route. I've been talked into sticking with the batteries that need watering a couple times now. Time to make a change.
