I paid a bunch for a pair of Interstate series 27 a few years ago. One of them went out really soon. I went back to the Interstate center and the guy checked both of mine and said "I'll make you a real deal". He offered to exchange my series 27s for series 29 for $20 bucks more. I asked if they were factory new and he said they were. I jumped on that deal. In a few months one of them wouldn't hold a charge for long. I got to checking around some of my fishing buddies who ran Interstates and found out the guy at the store had a pallet of new, old stock series 29s he had been pawning off on folks like me. No telling how old those two 29s actually were. When I went back to the store, they told me the story was BS and wouldn't do anything about either of mine. Last time I will ever darken their door. I ran them for some time then went to Everstarts and have had nothing but good luck with them.

My next battery purchases for my Terrova will be golf cart units.
