Pete purchased 16 12V Infinitum desulfators from us back in 2012 and another 10 in 2014. We managed to contact him for an update from his earlier testimonial he had left us in 2014.
The car that Pete is referring to in this testimonial is his Toyota Land Cruiser batteries which he got an additional 3 years of service life. The scrap battery he purchased for $5.00, intended to run his refrigerator is still running after 4 years. Here's a summary of how he benefitted:

The best time to install the desulfator is now. You will enjoy the best lifespan optimisation the earlier you start using it.
