![]() ![]() *** Assumes you started with a new battery costing $85 - $150 and lasting at least twice as long as it would without desulfating it. Applies to 12-Volt or 2 series-connected 6-volt batteries. Remember, the Manufacturer guarantees their performance with a 100% Money Back Guarantee plus a five-year “no hassle”, 100% parts and labor or full replacement warranty. If you answered yes to any of these questions, then you need a desulfating charger-maintainer. Do I want to win back the price of the battery charger before I need to replace the battery I first bought it for? ***.Do I want to use the lowest amount of electricity to charge my batteries?.Do I want to eliminate or greatly reduce battery maintenance (adding water, etc.)?.Do I want to them to charge as fast as safely possible?.Do I want the highest level of performance during their lifetime?.Do I want my batteries to last as long as possible (5+ years)?.Patented** method is this most effective way and VDC Electronics guarantees it with a Manufacturers’ 100% Money Back Guarantee plus a 5 year “no hassle” full warranty Here are the questions you should be asking yourself: In summary, if you want your batteries to deliver the very best performance and have the longest possible life, they must be kept free of sulphate by desulfating them in the safest, most effective way. In fact, the discharge rate doubles, as does sulfation, for every 10 ☏ rise above room temperature. Using or storing batteries in temperatures above 75 ☏ accelerates the rate of self-discharge and increases sulfation dramatically. It must be charged enough to prevent the battery from dropping below 12.4 Volts* (2.07 volts / cell). Even when stored fully charged sulfate will form without a frequently applied maintenance charge. This condition can be exacerbated with smaller lead acid batteries, such as motorcycle batteries. If they are overcharged, undercharged or left discharged for just a few days, they will rapidly develop sulfate. Batteries develop sulfation each time they are used (discharged – recharged). This includes the new sealed “dry batteries”, such as Optima, Odyssey, Exide and Interstate branded AGM-spiral-wound types. All lead-acid storage batteries will develop sulphate during their life time. Several battery charger companies claim a battery will not develop sulfation if it is always kept fully charged. Have a look at our Battery Minder product page to see our great selection No loss of electrolyte takes place in this process, thus ensuring sealed batteries, as well as “wet”, never die due to loss of electrolyte. It does this in the shortest possible time, without developing excessive heat. This immediately raises its specific gravity and frees the storage plates to now accept a fuller charge. The sulfuric acid, the major ingredient in a sulfate crystal, can then easily pass into the electrolyte (liquid, gel or absorbed type). With a slow charger, it takes a few hours to fully charge a battery, depending on the charged left in the battery. By generating just the needed range of frequencies and avoiding high voltages, we eliminate potential damage to the batteries storage plates known as “flaking”. A battery trickle charger, also known as a slow charger, continually sends a small amount of current to the battery (usually 2 amps or more, depending on the charger). They “dissolve” the sulfate rather than “destroying” or shaking it loose. Using just one fixed frequency may remove some, but not all, especially long established–hardened sulfate crystals. This ensures both old and newly formed sulfation will be safely dissolved in the shortest possible time. Unlike other pulse type battery chargers that claim this or similar sounding features, VDC’s BatteryMINDers® use a range of high frequencies. Recommended.Sulfation (sul-fay-shun), the number one cause of early battery failures, can be safely reversed, using high frequency electronic pulses. I needed to use the car a few days later and the engine turned over and started immediately without any effort. My heavy duty car battery was fully charged in just a few hours (I was expecting a trickle charge over days), so I tried the 'Recon' function to recondition the battery, but it didn't seem to need it much as that was also done in an hour or two. The display tells you what the current condition of the battery is and progress on charging. So simple, the biggest hassle is removing the tool kit and spare wheel from the car (mid-engined sports) to access the awkward location of the battery. ![]() It took a few minutes to understand the different options and capabilities of the unit before using it, but it was simple enough to use. The unit is very compact, with the battery connection cables and mains cable all fitting (very tightly) into a compartment at the top of the unit. I bought the DFX-150 to recharge my car battery as it wouldn't start after low usage during lockdown, and my old jump starter was long dead. ![]()
