I got the 6V ones from Costco and they have been great.
Actually then can and do! Our OEM Interstate U-2200's lasted one month short of 10 years and actually were still pretty good. We were headed out on a trip and I didn't want to have trouble on the road. The two 1000 CCA starting batteries were replaced only a couple months before the house batteries.
I did put 4 oz of moneral oil in each cell of the U-2200's, helped cut down on water usage and corrosion in the battery area.

Mineral Oil

Mine had to be replaced within a few months of us buying the Bounder. When I checked the dates on the ones I took out they were a year older than the build date of the coach. So indeed they were about 7 years old. The starting batteries failed even sooner.

Mineral oil? I'm interested. What kind of mineral oil did you use and where did you get it? I've read quite a few posts that say not to use drugstore oil, other that say it's fine, others that say mineral oil will make your batteries last forever, and some that say it will ruin them. Who you gonna believe?

I don't mind adding water. But the corrosion is starting to just plain piss me off! I have to scrape it off and spray with battery protector much more often than I think reasonable. The new battery retainer clips I coated with plastic are already starting to fall apart, and the little suckers were not easy to find!

Guess I'm a little late to the party, too. Don't mess around with tires that old. I've seen the damage a blowout will do to your rig (not my rig, thankfully.)

I have also used oil in my batteries and it mostly eliminated that caustic cloud of rust causing gas in the bat compartment. The product is called battery demister. Now it may simply be common oil colored red but it worked well. I used to work for a company thet sold electric scissor lifts and many customers used this because when you dont add water and expose the plates in the bat that section is dead. I add water much less frequently with the oil in there. I have no association with this company by the way.
