Sulfation and desulfation
Sulfation is the number one cause of premature golf cart battery failure. All lead-acid golf cart batteries will develop sulfation to one degree or another during their lifetime. Golf cart batteries form hard sulfate crystals each time they are used or discharged or are left in storage and not maintained in a charged condition.
Internal self-discharge of a battery can bring about the start of this condition in as little as three days in warm temperatures. Storing batteries in temperatures above 75 degrees F accelerates the rate of self-discharge and increases sulfation dramatically. In fact, the discharge rate doubles, as does sulfation, for every 10 degrees F rise above 75 degrees F.
Batteries not properly maintained and allowed to sit uncharged in storage in hot temperatures will self discharge and sulfate, and some permanent loss of capacity, distance and life should be expected. Even when stored, fully charged batteries will form sulfation without a frequently applied maintenance charge.
Batteries left in storage must be charged often enough to prevent the battery cell voltage from dropping below 2.07 volts/cell. We recommend using a trickle charger with built-in desulfator in warm/hot temperature storage.
If you want your batteries to deliver the very best performance and provide you with the longest possible life, keep them free of damaging sulfation by charging them immediately after every use (even short trips) and use a trickle charger w/built in desulfator in conjunction with your everyday maintenance charger especially in long warm temperature storage.
Sulfation, the number one cause of premature battery failures, can be safely reversed using an electronic device that produces high frequency electronic pulses called a desulfator. Electronic desulfators are the safest and the most effective way to keep your batteries free of damaging sulfation.
The most effective desulfators sweep a wide range of frequencies which ensures both old and newly formed sulfation will be safely dissolved in the shortest possible time. Using a fixed frequency desulfator may remove some, but not all, especially long established, hardened sulfate crystals.
The Battery Minder desulfator uses a truly unique patented method that dissolves sulfates rather than just shaking them loose. Potential damage to the battery’s storage plates called shedding, which reduces the battery’s capacity and life, is almost totally eliminated with top of the line desulfators by generating the correct range of frequencies and avoiding high voltages.
The sulfuric acid, the major ingredient in a sulfate crystal, can then easily pass back into the electrolyte during desulfating. This immediately raises the batteries specific gravity (ratio of acid to water), thus allowing the battery plates to now accept a more full charge increasing the battery’s capacity and the cart’s range of distance. No loss of electrolyte takes place in this process and it is done in the shortest possible time without developing harmful, excessive heat.
