My 318 had a brand new Strongbox in it when I bought it. Two years later, it was spewing acid out the vents. Some electrical checking showed that it would not charge up beyond around 13.2 volts; any attempts to charge it further turned into electrolysis of the electrolyte, causing the spew. The voltage output of the voltage regulator is about 14.5 volts on my tractor, so the problem was obvious.
My solution was to get an Interstate MT-26 battery. I don't know if the battery cables on my tractor have been replaced, but the Ford reverse terminal configuration would not install with the terminals on the front side. The MT-26 has the terminals "straight," that is, reversed from the 22F battery that Deere specifies for the tractor. Made a neat installation, and I think the Interstate is on its fifth seasons. Of course, I had to remove the battery tray and pedestal sides, repaint them, and do a good baking soda cleanup in the pedestal area.
I have bought only Interstates for the past twenty years, for all my needs. That includes the U1 tab type used in most small tractors. Not necessarily the cheapest to be found, but I've run Interstates in vehicles for ten years and replaced them because I didn't want to gamble on them lasting longer.
