About BatteryMINDers
BatteryMINDers® are the new generation of SMART, pulse type "computer-on-a-chip" chargers, that safely charge and maintain all size / type / brands of batteries including starter, deep cycle and sealed types including AGM “dry” made by OPTIMA, ODYSSEY, EXIDE, INTERSTATE, et al. They do all of this without ever overcharging, no matter how long they are left on charge – days-weeks-or even months. Dubbed the chargers with "brains," they are the first to fully-automatically reverse the primary cause of early battery failure known as "sulfation". Sulfated batteries once considered beyond recovery can now be brought back to long-term useful condition. Certain models of BatteryMINDers® can more than double the useful life of new batteries.

What is Sulfation (sul-fay-shun) and How Does It Affect Batteries?

When batteries are improperly maintained (over-under charged or left uncharged for extended periods) small crystals of sulfuric acid from the battery’s electrolyte (liquid or paste) form on the battery’s charge plates. They act as a resistor (barrier) preventing the battery from ever again accepting a full charge, no matter how long a charging source may be connected. Once this occurs, the cranking power of the battery is severely reduced, as well as its life. Aviation batteries are affected the most because they have been designed for maximum performance in the smallest-lightest case possible.

VDC Electronics has developed simple, but highly effective circuitry, able to safely dissolve sulfation, restoring much, if not all, of the lost power, providing the battery’s cells are not shorted or structurally damaged. This U.S. Patented approach is believed to be the most effective method for eliminating even the oldest hardened sulfate. By generating safe, wide-band, random frequency electronic pulses, we are able to cover the full range of sulfate crystals sizes, in the shortest possible time. Depending on the amount of sulfate and its age, complete de-sulfation can occur within several days to several weeks. De-sulfation takes place automatically, while the battery is being bulk or maintenance level charged.

Note: Both BatteryMINDer models (12-V or 24-V) provide “full-time” de-sulfation. We guarantee to safely eliminate all sulfate from any non-commercial aviation battery meeting the criteria clearly stated in our Instruction Manuals.

What makes the BatteryMINDer® desulfation method unique?
Sulfation (sul-fay-shun), the number one cause of early battery failures, can be safely reversed, using high frequency electronic pulses. Unlike other pulse type chargers that claim this or similar sounding features, VDC’s BatteryMINDers® use a range of high frequencies. This ensures both old and newly formed sulfation will be safely dissolved in the shortest possible time. Using just one fixed frequency may remove some, but not all, especially long established – hardened sulfate crystals.

Our U.S. Patented methods are truly unique. We “dissolve” the sulfate rather than “destroying” or shaking it loose. By generating just the needed range of frequencies and avoiding high voltages, we eliminate potential damage to the batteries storage plates known as “flaking”. The sulfuric acid, the major ingredient in a sulfate crystal, can then easily pass into the electrolyte (liquid, gel or absorbed type). This immediately raises its specific gravity and frees the storage plates to now accept a fuller charge. It does this in the shortest possible time, without developing excessive heat. No loss of electrolyte takes place in this process, thus ensuring sealed batteries, as well as “wet”, never die due to loss of electrolyte.

Several charger companies claim a battery will not develop sulfation, if it is always kept fully charged. This is incorrect. All lead-acid storage batteries will develop sulphate during their life time. This includes the new sealed “dry” such as Optima, Odyssey, Exide and Interstate branded AGM-spiral-wound types. Batteries develop sulfation each time they are used (discharged – recharged). If they are overcharged or undercharged or left discharged, some for even just several days, they will rapidly develop sulfate. Even when stored fully charged, sulfate will form, without a frequently applied maintenance charge. It must be charged enough to prevent the battery from dropping below 12.4-Volts* (2.07-volts / cell). Using or storing batteries in temperatures above 75°F accelerates the rate of self-discharge and increases sulfation dramatically. In fact, the discharge rate doubles, as does sulfation, for every 10°F rise above room temperature.

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.  BatteryMINDers’ U.S. Patented** method is this most effective way and VDC Electronics guarantees it with a 100% Money Back Guarantee plus a 5 year “no hassle” full warranty.

Here are the questions you should be asking yourself:

• Do I want my batteries to last as long as possible (5+ years)?
• Do I want the highest level of performance during their lifetime?
• Do I want to them to charge as fast as safely possible?
• Do I want to eliminate or greatly reduce battery maintenance (adding water, etc.)?
• Do I want to use the lowest amount of electricity to charge my batteries?
• Do I want to win back the price of the charger before I need to replace the battery I first bought it for? ***

If you answered yes to any of these questions, then you need a desulfating charger-maintainer. Remember, we guarantee their performance with a 100% Money Back Guarantee plus a five-year “no hassle”, 100% parts and labor or full replacement warranty.

* At room temperature. Applies to 12-Volt or 2 series-connected 6-volt batteries.
** U.S. Patent No. 6078166
*** Assumes you started with a new battery costing $85 - $150 and lasting at least twice as long as it would without desulfating it.

Excellent Video on RVEducation101 about Batteries and the BatteryMINDer
I highly recommend viewing this entire video before using your BatteryMINDer.  It is great at describing the benefits of BatteryMINDers and is a good training video on how to use them.

Not for use with Aviation Specific batteries.
Note: Most gliders use batteries which are not "Aviation Specific".  The Power-Sonic batteries sold by Cumulus Soaring, Inc. are Absorbent Glass Mat (AGM) type batteries.  AGM batteries (and all glider batteries I've seen) work great with BatteryMINDers.

An Important Question
An Important question you should know the answer to before making a buying decision:
Why would you or anyone pay up to $150 for any battery charger, when there are dozens of much less expensive, good quality chargers from which to choose?

Answer:

1. The cost of the average starter or deep cycle battery is $85, with an average-life of three (3) years (200 full charge – discharge cycles). Many types, such as sealed AGM, Gel or spiral-wound “dry” (Optima, Odyssey, Exide, etc.) cost considerably more ($125 - $175 ea.). They also will not reach their full design life of five or more years, unless they are properly “treated” during their entire lifetime.
2. The Average performance of all battery types, over their life, diminishes to 50% of original. Measured in either cranking-amps (starter type battery) or ampere-hours (deep cycle battery), your battery has “shrunk” when compared to its original performance and capacity by 50% or more, before it finally dies. The major reason (believed by many authorities to be 75% -90% of the cause) for this loss is not just “old age”, but a condition known as "sulfation”.
