Battery De Sulphation Science Or Fiction

by Curt Hudek, PGA

Don’t you just hate it when you go to change the channel on the TV and the battery to the remote is dead? Then you remember back to the day when you used to have to get-up to change the channel and chuckle about how getting up to change the channel is such a thing of the past. Dennis LeBlanc of Battery Rejuvenators feels like the same paradigm shift may take place in the next few years with respect to the replacement of many types of batteries.

Dennis currently owns and operates a company appropriately called Battery Rejuvenators, which recently began exploring golf car batteries as an application for their product line. Dennis worked successfully for several years with industrial type batteries, which typically cost $6,000 each, in extending the life of batteries saving warehouse managers thousands of dollars while enabling them to defer significant capital investments.

So how does it work? Basically it is relatively simple—most lead batteries (Forklifts, cars, golf cars) build up layers of sulfur deposits on the lead plates that are layered inside the battery casing. This build-up reduces the battery’s ability to hold a charge, require more energy to charge and reduce the battery’s performance. A typical golf car battery loses efficiency after one year, even more after two years and in the desert heat is generally nearly expired after three years. …or right in the middle of one of your better rounds of golf on a hot summer day! The “Rejuvenating” process is able to “knock off” most of this sulfuric layer enabling the battery to once again take a full charge and perform very close to that of a new battery.

Eddy Renio, PGA in Sun Lakes introduced Dennis to the SWSPGA a few weeks ago. Eddy spoke of how he and Dennis had performed this rejuvenating process on approximately 70 private golf cars in Sun Lakes. 95% of the Golf Cars showed significant improvement in “run times” following the procedure and the members were very pleased with the performance of their golf cars following the process. When asked about the three golf cars that did not show improvement Dennis explained that while the process could “rejuvenate” a battery it could not “resurrect” a battery—in other words once a battery is dead—it is dead!

The process takes between thirty and forty minutes per golf car (depending on the age and usage of the golf car) and generally will extend the life of the battery by 50% providing there is reasonable life left in the battery. Dennis has significant research and testimonials on this procedure and invites you to give him a call or if you would like an outside opinion feel free to call Eddy Renio at Ironwood Country Club! (Eddy even had the process done on his father-in-laws private golf cart—that is confidence!)
While the process has benefits to the individual with a private golf car—it could have significant benefit to golf clubs with their entire fleet, golf course maintenance equipment and beyond. Dennis is looking forward to working with golf courses in addition to the heavy equipment industry. You can find Dennis at
