While it is true that Sam's does not carry the Interstate brand,,, The fact is there are no interstate batteries.. They are made by one of two companies. One is Johnson Controls. (And I'm not 100% sure of the other) .
Who makes the batteries Sam's does sell?
I just got two small (Lawn Tractor) batteries for my wife's mobility scooter, These U-1 size 31 amp hour batteries replaced a pair of 17 amp hour AGM's that died young, as AGM's often do (they are the shortest lived of the options we have).
They are the Wal-Mart house brand.. "Distributed by Johnson Controls" clearly fine printed upon them.
Oh, wife is very happy, the six year old AGM's. (Like the six year old East Penn AGM's I had in the motor home) were getting very weak, These new ones give her scooter about 2x the range it had when the batteries were brand new.
The "next newest" batterys in my coach are the OEM's 1 maintenance free starting battery, and a pair of Interstate U-2200s.. All going strong. I also have a Group 29 Maintenance free that is.. Not so good.. It will be the next to get replaced, it is OLDER than the RV however by a few years.
