Richard ...I believe you may have normal 3 stage
charging confused with EQ'ing a battery. The three stage process is BULK, ABSORBTION/Acceptance and FLOAT...though the numbers you quote from Sterling are a bit high compared to other mfrs. of open wet cells...they do represent those 3 stages. EQ is a separate function generally performed on open lead acid batts at 15.5V or so for 8 hours or so to
repair sulfation. Each mfr. will have their own parameters based on their construction and materials formulation.
Now...as to the issue of SEALED wet cells (as opposed to sealed AGMS/Gels...they operate on the prinicples of open wet cells and use a large sealed chamber to hold extra elecrolyte so you don't have to fill them with
water. This normally works well but since there is no way to get more
water in...you have to avoid boiling off the original electrolyte which is what EQ'ing will do to them. The result is the same as not adding water to your open batteries...exposed plates and battery death.
MOST
AGM mfrs. discourage eq'ing as well for similar reasons. Probably
legal departments are responsible for this for if you talk to people, they will tell you that you can do it but only if you follow their parameters and keep an eye on things while you are EQ'ing. If you do EQ and ruin the batteries...you should not expect the warranty to be honored.
Lifelines are different in terms of recommendations but I would still be careful and keep an eye on them.
motion - Running the EQ in 1 hour increments should not be a problem IF you can get the 8 cyles in REASONABLY close to each other without being fanatical about it!
