All solar batteries degenerate in performance and lifespan from a process called sulfation. Sulfation is a build up of an insulating layer of spongy sulfate crystals which occurs whenever a battery discharges. The live of the battery or active material become lodged in an unusable crystalline form. The process reverses whenever the batteries are charged. However since the amount of time where a battery is discharging is higher than when it is charged, over time the sulfate crystals harden and cannot return as active material even with charging.
A customer from Canada, Joseph Wong, recently sent us images of his installation of four 24V Infinitum Desulfators on his 24V solar battery bank made up of eight 12V batteries. We see here four parallel rows of two 12V batteries in series. One 24V desulfator is installed on each two 12V batteries in series.
Below is the image of the actual installation, an illustration of that installation, an example of a 48V battery bank setup with 24V Infinitum Desulfators as well as a snapshot of his comment on this article in which he mentioned that there was an apparent improvement after using the desulfators for three weeks.
Most batteries in warmer climates like the one found in the tropical climate of Malaysia usually last 1 to 2 years. The doubling of the battery life span that Dr. Nizam enjoyed from the single Infinitum Desulfator unit he purchased from us not only saved one but two batteries and will continue to do so for a few more batteries.
Below are images he sent us:
We received this product review from Joe recently. Find the full review below:
Dutch mariner, Meijlink purchased three 12V Infinitum Desulfators from us back in July 2009 which he used for his yacht batteries. He purchased more a week ago for his friend and left this testimonial:
Mark purchased the 12V Infinitum Desulfator from us in November 2013 for his BMW 5 Series E39. He contacted us again recently after over 3 years to purchase another unit for his other BMW, a BMW 6 Series E63. He saved a whopping MYR3000 (about US$750), which is the price he would have spent to replace his battery. That is a significant on his return on investment.
Tamz left this testimonial on Facebook of how he managed to recover his solar batteries that were no longer able to accept a charge. In the image you would note how he has hooked up the 24V Infinitum Desulfator in parallel with two 12V batteries that are hooked up to make up 24V.
The testimonial is a mix of Filipino and English. Below is the translation:
Mike from Philippines successfully revived his solar batteries which at 4-years-old began to show a significant drop in performance. Mike placed the desulfator into action having promptly received his order. Here is the English translation from the Facebook testimonial he posted:

We've received yet another testimonial on a jump starter battery recovery after using the Infinitum Desulfator (The previous one was on a Century Jumper 850). This time it is a Stanley Fatmax 350 Amp jump starter. The 12 volt 7.2 Amp hour sealed lead acid or SLA battery could only hold a charge at 11.8 volts but after charging it with the Infinitum Desulfator installed at the same time for a day, the battery now is fully restored to hold a charge at 12.6V. More importantly, the Fatmax can now crank up his Isuzu without issue.
Jump starters have built in SLA batteries that provide the power to work. These batteries, similar to automotive batteries, will also experience the 'cancerous' process of sulfation. If left untreated, the battery will die in half the time that it was made for. In other words, that's good money down the drain. With the Infinitum desulfator, this growth of sulfation is reversed and returning the much needed active material back into the battery. Not only that, the Infinitum is reusable, so you can expect to recover many batteries throughout its long service life.

I have bought more of your product after being totally amazed with result achieved having bought one to trial on a Heavy Duty Battery that was showing signs of failure in a VW Diesel car. That was a month ago and the battery is now performing as if new and those tell tale sounds made when a battery is failing to produce enough starting current have completely gone. So satisfied with your product that I have bought these additional units and I will install them on all vehicles with battery powered starting.
We got in touch with Rob Denton late last year to find out how the desulfator he purchased from us in October 2010 was faring after 5 long years. And we were pleased to know that it was still working fine.
Rob is a licensed amateur radio enthusiast based in Nottinghamshire and uses a 3 kilowatt uninterruptible power supply (UPS) with 8 batteries as backup power for his weather station computer and radio equipment. This was the testimonial he left us in 2010:
We also found out then that Rob is a regular contributor to the quarterly journal GEO (Group for Earth Observation) and wrote an article which appeared in the GEO Quarterly No 33 in 2012. He was kind enough to search through his library to send us the image of the article. We have transcribed the article below for easy reading.
