Sulfation, is the number one cause of early golf cart battery failures

It has long been known that a Golf Cart as well as other application lead-acid batteries, sealed AGM or
flooded (wet cell-filler caps), when used infrequently, lose power and have shorter lives than those used on a more
regular-daily basis.  Batteries develop sulfation each time they are used (discharged – recharged). If they are overcharged, undercharged or left discharged for just a few days, they will rapidly develop sulfate.

However, it can be safely reversed, using high frequency electronic pulses. Some people claim a battery will not develop sulfation if it is always kept fully charged. This is not correct. All lead-acid storage batteries will develop sulphate during their life time. This includes the new sealed “dry batteries”, such as Optima, Odyssey, Exide and Interstate branded AGM-spiral-wound types.

By doing so, otherwise healthy batteries, those which have lost no more than 20% of their power*, can expect improvement to an 85% or greater level of performance.

Prevention beats rehab, every time. With BatteryMINDers’ ability to fully charge,without ever overcharging, no matter how long left connected, there is no reason sulfation should ever become an issue. Further, without sulfation ever reaching damaging levels and the battery never subjected to overcharging, life and performance can be expected to be several folds better than any battery left to self-discharge, as is typical of so many golf car batteries.

Testing Your Battery For Sulfation

The following, if done correctly, will tell you more about the condition of your battery.
Use a Digital Volt Meter and a hydrometer.

Testing your battery for sulfation

BatteryMINDer Charger/Maintainer/ Desulfater
– 2 Amps for 48V Systems,

Step 1
Charge battery to as full a level as possible with a charger. Allow battery to “rest” which means don’t charge or discharge for a minimum of 12 hours.

Step 2

Measure the battery’s voltage using a digital meter. Record this reading. If your battery is a “wet cell” type (has filler caps) you can also test the Specific Gravity (SG) of the liquid electrolyte in each cell. Record the SG readings in each cell. For 48-Volt – minimum voltage for effective desulfation = 50.0 (wet cell SG reading 1265).

 

 

Step 3
Leave battery connected to your BatteryMINDer for a period of 72 hours minimum.

Step 4
Disconnect and retest battery voltage and SG. You should measure an increase in the voltage and SG, indicating
desulfation is taking place i.e. The sulfuric acid that was in the sulfate crystals has now returned to the electrolyte
where it came from originally.

Step 5
Continue leaving battery connected to BatteryMINDer for an additional 72 hours minimum and test again. Continue this testing until you no longer measure any improvement (increase) in the battery’s voltage (and SG, if wet cell).

Conclusion
Desulfation, via variable high frequency pulses, dissolves sulfate from any type sealed or wet cell lead-acid battery.

By doing so, otherwise healthy batteries, those who have lost no more than 25% of their power, can be expected to
improve to 85% or greater level of performance.

Note: Increases in battery voltage and a wet battery’s electrolyte specific gravity, will be very small and depend on
how sulfated the battery was, and how long the sulfate has been deposited on the storage plates.

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.
