It would help if you say what machine, etc. so people have a reference.
And an auto parts store or tractor supply store should be able to cross reference your battery to the specs of your machine. just because a particular battery is in your machine does NOT mean it is the proper one to use as replacement.
I concur with the two dealers about the Interstate batteries- I used to sell them from my foreign auto shop for many years- they are buy far the best batteries. I have them in my cars, boat, tractor DK-35se/hst, etc.
