Elucidate Me...
Starting out with a 100 amp hour flooded battery, depleted to 50% what -exactly- does a person need to do to regain 100.00% state of charge. With this charger? How long of time is needed?
Anyone out there feel convinced they have aggregated a thousand hours of float time on a single B&D ?
Mex they don't float. I don't know why you are so skeptical of the 40a VEC1093DBD. I'd be lost without mine.
They get the battery to about 97% SOC and shut off saying FUL. Then you can go to the next step to get to 100%, which is to run the charger again in the 4amp setting with "equalize" on.
That runs for a while at a higher voltage in the 15s while amps taper from 4.1amps on down. This can take several hours or less than an hour, depending on the condition of the battery. The charger says FUL and now you check the battery SG. It might be up to baseline or not but will be close to baseline.
It might take a second run at 4a and E to get the SG all the way to baseline if the battery has been doing some 50-90s previously and got in rough shape from doing that. The second run does not take as long as the first. Now your battery is at 100% and can go on a float charger if you have one.
The beauty of the VEC doing that overcharge is you can do it overnight while sleeping, because it is automatic and shuts off by itself. No need to be there to monitor the equalize session as with a manual charger.
I don't know anything about its failure rate but mine is six years old and has been used many times. I did change its fan to make it quieter, but that was not a performance issue.
