- Why volt meters are NOT accurate in determining battery health:
When you connect the SOC140’s test cables to the battery under test, the SOC tester's Voltage Analyzer will show you the present voltage of the battery prior to test. The initial reading of the Voltage Analyzer will be the same as a multi-meter reading set to read the voltage of the battery under test. Once you dial in the SOC140 and start the test, the Voltage Analyzer will show you the voltage of the battery while the SOC140 is examining the internal profile of the battery under test. It will also display the final voltage after the test is performed.
Here is a one specific example of a false positive utilizing a volt meter:
-Say you were to take two 20 AMP HOUR 12 Volt batteries off their charging systems at the same time and each one of those batteries read 13 volts off the charging system utilizing a volt meter. Both those batteries would be good right? Not Necessarily.
Take the same batteries and test them with an SOC140. The Voltage Analyzer on the SOC140 will show the same reading as a volt meter before the test starts. After starting the test, the SOC140 will show you the voltage drop of each battery under test during the 43 second analyzing process.
You may see one battery's voltage drop further at times through the test sequence than the other. Even though the initial voltages were equal, the final evaluation of the battery's health may be different. One battery could have a final reading of 60%, while the other could have a 100% reading. If you had utilized a volt meter to perform the tests, you would have passed both batteries due to reading only the surface charge of the batteries under test. If you had utilized an SOC140 you would have only passed the good battery. The damaged battery would be replaced and the ups system's reliability intact.
These SOC140's results are commensurate with actual 20 hour discharge tests. In other words, if you were to completely discharge the battery as per the manufacturer’s recommended 20 hour discharge rate, you would get the same results you get from this tester in 43 seconds. Most importantly, the battery will not be fully discharged at the end of a SOC140's test. It will be able to go right back online with the ability to perform to it's maximum potential immediately.
-Inadequate test cables are a clear indication of an inadequate load test: You need to put enough of a load on the battery under test in order to be accurate in evaluating its condition. There is simply no way a load tester that has thin gauge cables can be putting an adequate load on the battery under test to properly evaluate that battery's capacity.
Any Tester can be manufactured to put a load on a battery, but the load must be precisely applied and predetermined to change based on the AMP hour capacity of the battery under test. Without this method, the results on a different AMP Hour battery with the same tester can not be accurate either. Would you apply the same load to a 10 AMP Hour Battery as a battery with 10 times the AMP Hour capacity? It doesn't make sense. The load would have to be ten times the amount to keep all constants. Change the constants, lose the accuracy.
String analysis leads to an unreliable system
If you were to find an "accurate" string analyzer and test the string of batteries above, you would find a combined reading of 92.5 %. In other words, this string would be able to produce 92.5% of its rated power. 92.5% would be adequate as long as your system is engineered to have more backup capacity than is necessary. This is usually the case.
In the example below the system would not be reliable, efficient or stable. The problem with utilizing a string analyzer is that you cannot determine if one or all of your batteries are performing as they should be. You only see the combined value.
To a string analyzer the two examples are the same:
100 + 100 + 70 +100 / 4 =92.5
92.5 + 92.5 + 92.5 + 92.5/4 =92.5
So either way you have adequate power for your application and a reliable system, right? WRONG. What you have is a weak link in your string, which is detrimental to your system's reliability and efficiency in more ways than one.
The good batteries in the string will be compensating for the bad battery. This compensation situation will shorten the life of the goods batteries in the string. If you remove the weak link, you will be increasing the life of your good batteries and thus decreasing your battery replacement costs while maximizing reliability.
Even if the majority of the batteries in your system are 100 percent, the weak link in your system may fail. When it does, your system fails. The string is only as reliable as its weakest link. Utilizing the SOC140, you find the weak link or links and maximize the reliability of your string.
-Temperature compensation: If the device you are using is not compensating for the temperature of the battery under test the results may be off by up to 50%.
Battery capacity (how many AMP Hours the battery can hold) reduces as temperature goes down, and increases as temperature goes up. The standard rating for batteries is room temperature or 25 degrees C (about 77 F).
At freezing, capacity is reduced by 20%.
At 122 degrees F, battery capacity would be approximately 12% higher.
At approximately -22 degrees F (-27 C), capacity drops by 50%.
-Cooling Fans: If the tester you are using does not have any cooling fans to cool a heat sink that is integrated into the load tester, the temperature of the load resistance function will effect the accuracy of the load applied to the battery. If the resistance function of the tester is not temperature controlled and precisely applied the results are not as accurate. When you are testing multiple batteries, you need a cooling process or you need to wait for the tester to adequately cool between tests. The absence of an integrated cooling system results in wasted man hours to allow for proper device cooling between tests.
-Appropriate Ampere Hour Compensation: In order to get the proper results from a test, the device you are using must have the ability to be specifically dialed in to the AMP Hour capacity of the battery.
If you are testing a 20 Amp Hour battery you need to apply a load designated specifically for a 20 Amp Hour load. When testing a 110 Amp Hour battery you would apply a load designated specifically for a 110 Amp Hour battery. If you are using a tester that applies the same load to a 20 Amp Hour battery as a 110 Amp Hour battery the results cannot be accurate, because of the difference in the specific AMP Hour capacity of the battery.
-Simplicity of Operation: In order to appeal to the masses we have designed this tester with the novice in mind. We know that the last thing you need in your company is countless hours taken away from work and spent training your technicians. The technology is complicated, but operation is simple as can be. It should take you about 5 minutes for anyone to master the device. Set the battery's AMP Hour Rate, Temp, Voltage and push the start button. The device will do the rest and in 43 second you will have the actual 20 hour discharge results of the battery as if you had discharged it yourself under controlled lab conditions. The other benefit is that the battery will not be depleted and possibly damaged as a result of the full discharge test.
-Relying upon Good, Marginal or bad, may be VERY BAD!
How important is precise accuracy of an SOCtester as opposed to the good, marginal or bad reading provided by other inferior battery test equipment? How important is it to the customers relying on their batteries? Unless you are grading a kindergarten assignment, good, marginal and bad evaluating may be about as useless as you would think it could be. The standard for the industry for a passing a battery is anything above 80%. If you don’t know what the actual percentage of the battery is, you are left in the dark and need to rely upon the reliability of the tester.
So just how reliable are your current testers results? Usually the manufacturers of battery test equipment have a hard time trying to get repetitive accuracy and reliability utilizing their own devices. When you are relying on good, bad and marginal evaluations the testing device may be producing internal readings within a certain realm of 20% to 30%. Utilizing the Good, Marginal and Bad practice, the tester may reveal the same “good” reading every time. What you don’t know is whether the testing device is reading 100% the first time you test, 80% the second time and 90% the third time on the same battery under test. All you see is “good” as an evaluation. The tester’s evaluation may be off by as much as 20%-50% without you even knowing it.
The good, marginal and bad evaluation process is a way of compensating for a lack of definitive accuracy. In the case of emergency systems and vital ups system power, you need to know the specific state of charge of your batteries and be sure of your tester’s accuracy and reliability. So what is the bottom line? You simply cannot rely upon an evaluation that is inconclusive.
The Load process is critical in evaluating battery health. The Process by which you apply the load to the battery under test is vital to test accuracy. This is yet another process that separates the SOCtester from the rest. Our tester scans the infrastructure of the battery. It examines the batteries internal profile and determines the state of charge. This state of charge directly correlates to the batteries 20 hour discharge characteristics. Every UPS battery has a 20 hour rate. The 20 hour rate is the best way to determine the health of a battery as determined by the manufacturers. The bottom line: The SOC tester has been shown through controlled lab tests, conducted by companies that have utilized our equipment, to have results commensurate with the actual 20 hour discharge test results. You just can't get more accurate than that.
Don't Be Fooled By The Copycats! Over the years, we have had many try to copy our patented testing methods. Unfortunately for them, they based their test equipment on our previous piece of test equipment, the Powercheck series. The problem with their inferior design and interpretation of our testing method is that the accuracy of their attempt to copy, while still remaining free from infringement, will not allow them to realize our level of Accuracy, Reliability and Consistent Evaluation Repetition.
Besides inadequate development due to infringement issues, their limited interpretations were based on our previous models of testers and not the new SOC140. The bottom line: They do not have a clear understanding of our testing methods. We are the best for a reason and we intend to stay that way. Don't be fooled into purchasing a partial and inferior interpretation or our test methodology. We can guarantee you will NOT get what you paid for no matter what the price.
-Reputation: We are not the only battery tester on the market, not the least expensive (like the $5.95 testers that pass every battery with any voltage) and not the most expensive (some selling at $6000 requiring intense training, sophisticated software manipulation and computer integration, with results that are bottom line still inferior to our patented testing method, but with all the bells and whistles to fool you into thinking you are getting the best results.) We are however the most accurate tester on the market. We could sell our product for thousands more. Our previous model, which was far inferior to the present model, sold for more than $3700 With thousands sold to date. Our new and improved model is much more versatile, but with a price that is more affordable as well. The competition is simply not worth the money when compared to our device. Whether you are buying the $5.95 or the $6000, you may as well be throwing your money away. The results of our tester and its reputation clearly speak for itself. One of the largest testing companies in the world conducted their own independent lab tests on our tester. The tests consisted of comparative analysis of our testers results, the results of several other testers on the market and actual full discharge test. Not only did our tester come out on top, it was the only accurate tester evaluated. As a result the SOC140 is now the standard for their company. Shouldn't it be the standard for yours? Show me more
