Scratchin my head on this one. My original battery lasted a bit more than 10 years. It still cranked but had a hard time starting the RTV down in the 20's. So, an outfit here, Votex Batteries carried the original equipment. I think they supplied Kubota as they are right down the road from the mother ship factory.
So, I went to the local Voltex battery dealer and got the original style and stuff for $89 or so. Yes, I have to run the lights a bunch without the engine running, that's the regular lights and aux lighting on the roof or back when working on stuff in the night. I guess I could run a radio for quite a bit longer................
What does matter is that the original never failed me so why mess around with something that works? Not being an electrical design engineer. I just stick with the girl that brung me to the dance. .........It really doesn't matter, it's what you use and how it does for YOU.............God bless......Dennis
