If your battery boils a little everyday during the charge period, you never need to equalize. When they set unused for a long period of time (Back-Up Power) and the charge just floats, then you need to make them boil to mix them up..

I set my bulk charge (12 volt system – C-40 Controller) to 14.2 volts. This voltage makes them boil for an hour then the float charge drops to 13.6 volts. I must be doing something right, being I got 8 yrs. out of a set of golf cart batteries, and they were still working when I replace them. I NEVER equalized once.. (I did a load test and they were getting weak)

I do use a desulfation unit. Installed it long ago. I know of Fire Departments that use this exact unit on their batteries and it sure helps. Cuts their replacement in half..
