Ablative shedding PT :)
A 5-amp battery maintainer would allow safe storage when the battery is at 95%. Don't play games trying to store a battery with <85% full. You will lose. I do realize tenders of 5 amps are not common but try for the highest potential.
This is where you see the value of a Meanwell or Megawatt. Mere TOP CHARGING eliminates the need for equalizing up to 95%. Set for 15 volts. When 15 volts is reached a vague timer can be used to charge one hour per battery additional then shut off. VAGUE is just that. 15 volts. If curious do look at the cells. When they bubble you're done.
Triple-digit IQ allows a user to incorporate a wristwatch to TIME the top charge and then incorporate the elapsed time from then-on instead of using visual bubbling.
But then you can forget all this and just buy batteries twice as often.
EVERYTHING above is for flooded batteries.
And is calculated from 30 years of experimentation and verification by autopsy.
