"A scrapped battery I purchased for A$5.00 in April 2012 is still functioning today!
My son and I have not bought a new battery for at least three years,
and none of our batteries have died since fitting the units."
Toyota Landcruiser and Scrapped Battery Optimised
As far as performance of the Infinitum desulfators, I have one on each of the two batteries in my Toyota Landcruiser. One of the batteries was about 5 years old and probably near the end of its life, when I fitted the first unit (desulphator) in March 2012. This battery is still starting the cruiser.
The other battery is one I picked up outside a tyre service for scrap price of $5.00. I immediately fitted a desulphator and it is still running my 12 volt fridge/freezer as well as auxiliary starting. That was in April 2012.
Solar Deep Cycle and Tractor Batteries Recovered
My son has a caravan/shack on our farm and has a solar panel to power his TV, external hard drive, laptop computer and his lights. He has two of your units, one on each of three batteries. He swaps one unit between 2 batteries. These batteries were thrown out of refrigerated trucks and had been recovered with your units and been in use since April 2012. He also has two batteries that have been recovered in his Landcruiser.
I have a tractor that has a battery that's been recovered with one of your units and the rest of them (your desulphators) are recovering batteries for future use.
I use your desulphators on my trailer sailer batteries as well. Here's an image of me in my boat sailing in the Gulf of Carpentaria, Queensland.
We have not bought a new battery for at least three years, and none of our batteries have died since fitting the units.

Note from Infinitum:
Peter purchased 16 12V units in 2012 for his personal use on various applications, his trailer-sailer as well as for his friends. At the time of this post, he purchased an additional 10 12V desulfators.
