A little question about desulphators

by tranha2 » Thu Mar 08, 2018 2:15 am

We have 3 pairs of one-year old golf cart batteries, but no reasonable way of running them up to 16 V or so periodically

Any real world experience with desulphators ???

Any recommnedations on brand?

Or best to avoid them?

If you are referring to devices that claim to desulphate batteries with pulsation current, variable DC frequency and similar, based on extensive tests by independent marine electrical experts they are all complete snake oil.

The best thing you can do for your batteries, other than fully charge them as often as possible and avoid really deep discharge, is to get a charger that will do equalization. Do you have a smart charger with an EQ mode? Can you connect to shore power occasionally? I believe the better solar chargers can also do this and possibly a smart alternator regulator.
The water is always bluer on the other side of the ocean.

Do you have a solar charger? We used our Outback MPPT solar controller to run our lead acid batteries up to 15 volts when they needed it. We had a large battery bank, and to get the Outback to push the batteries up to 15v, we had to split the bank and only do half of the bank at a time. It took patient monitoring, and perhaps several cycles of a few hours in the middle of the day per bank, but it did the job. Our Rolls Surette batteries lasted (6v lead acid forklift batteries) lasted about 8 years of nearly full time cruising.

We also added a "nano pulser" to our circuit, but hard to tell if it did anything (but make noise on the SSB). We still needed to equalize the traditional way periodically.
