I installed the desulfator two days after receiving it. There was immediate results via faster chraging and slower discharging. I have shared your information with my neighbor, a Hawaiian electric engineer who recently bought a small 2,400 watt solar system. I am toying with other possible applications now that I know how well it works. It is a near miraculous device, it would be criminal not to use it on every battery system at home or work.

     Since we have placed the S280 on our 2 1/2 ton trucks, we have never had a problem with a dead battery. It's great knowing that when we need to use this vehicle it is always ready to go. We haven't had to replace a dead battery since we installed this unit. I would recommend it for all vehicles.

     We use the S-1000 on our equipment and have had no problem with dead batteries since we installed them. I can see that the units are working and know that my engines will always start and be ready to go when I need them. It's one less thing to worry about.

     We installed the S-280 and S-550 units on our rental gen sets five years ago and we haven't had to replace a battery since. It's nice to know that when my customers need our equipment, it is always ready to go. No need to worry about having to charge batteries that have been sitting for long periods of time. I would highly recommend these units to anyone who is thinking about using them.

      I have been using the S-550's on 8D and 4D batteries that are used with our generators for the past three years. The units are working great. I can see purchasing additional units in the near future.

      We installed the S280's on our aircraft support equipment and we are very pleased with their performance. They were installed last year and we have not had to replace the batteries on any of the equipment.

     I want to thank you for telling me about Innovative Energy Desulfators. Since desulfation products for batteries have been a fraud in the past, this last summer I thought I would do a little test before I started selling them to my customers. I have the perfect situation for testing without expensive monitoring equipment. I have an old GE Electrack electric lawn tractor that runs on 6 golf cart style batteries. When the batteries were new 4 years ago, I could mow our whole hilly lawn on one charge. Now before my test, I could only mow 1/2 the yard on one charge.
     I thought that if the DeSulfator was working, the range on the tractor should increase. I installed a D-500 36 volt Desulfator across the series string of 6 6 volt golf cart batteries. Within on month I was amazed to find the range on the lawn tractor had returned almost to what it was when the batteries were new. I could now mow 90% of the lawn in one charge. By the end of the summer, the range was back to what it was when the batteries were new. (i.e. being able to mow 95% of the yard in one charge).
     The purchase of a Desulfator saved me form having to buy a whole new set of batteries. My test is now on-going to see just when it will be that we have to buy new batteries.

     I purchased a DeSulfator unit in May of last year. The increase in performance of my system has been nothing short of remarkable. My system is a 24 volt made up of 8-6 volt Trojan batteries that were 2 years old at the time of installation of the DeSulfator. A typical days use would pull the batteries down to as low as 19 - 20 volts. After 2 months of having the DeSulfator connected, the batteries rarely drop below 23.5 volts. The amount of energy available is obvious.

     But...on the 12 volt DS-500 DeSulfator from IES...I've been able to perform several tests. I'm not quite ready to write this up "officially" right now, but can offer you this unscientific version of my findings.
     On 2 650 CCA start batteries (app age of 1 year).....both of these had been left completely discharged for several weeks after having failed prematurely due to abuse (not mine!). Both failed to accept a charge using a conventional 2/10/50 amp Schumacher auto battery charger. The DS-500 was connected to each one in turn and charged again...using the same charger and the same charging times as previously. Both batteries appeard to fully charge and passed a 20 second (starter) load test with flying colors, although 1 of them did require a second round of charging. This battery had a slightly bulging case and appears to have been frozen. These batteries are now being used in various vehicles...in very cold weather...with great success (so far).
     On my old (3 years old) 90 AH trolling battery. This has been used for ship projects, demos and shows...and occasionally for 2 meter ham radio use. I'm ashamed to say that it's been severely neglected...by me and others that have borrowed it. It was returned by one person completely dry...no electrolyte in sight. Visual inspection showed severe sulfation. I've been throwing a charge at it whenever I had enough wind power here to justify the power usage. And over the pasy 12-14 months, I'd come to the conclusion that this battery needed funeral arrangements.
     Using the exact same charger and charge times that I had with many previous charging attempts, but now with the DS-500 attached, this battery was successfully charged. FYI...this was done with several back to back chargings over 3 days. The battery passed the 20 second starter load test with flying colors, powered my 12 volt/50 watt drop light for 19 hours and after being fully recharged has now been sitting, unused on my bench for 6 weeks. At this moment, it has only self-discharged down to 85% capacity and just passed another 20 second load test. Not too shabby for that old timer!
     I'm going to start on my old (and heavily sulfated) golf cart batteries next week. And I should have my 24 volt DC charger back shortly and can start on the 24 volt DeSulfator test. I'll keep you all posted.
     One final note...I fully realize that these tests don't conform to standard testing procedures and won't satisfy a lot of folks. But...being a non-believer myself, I'm rapidly becoming convinced that there is definitely an advantage to using these DeSulfators. Something is happening here which is allowing me to "bring back" batteries which I would normally throw away. And the results I'm getting by using "real world" testing (using them in vehicles, etc.) certainly cant be ignored. Further testing and study is definitely required but so far, so good.
