Note from Infinitum:

Tony Castleman left us a note on our Facebook Page yesterday to update us on how he is still benefiting from the desulfator units he purchased from us in November 2007. (Do excuse him if he got the date of his purchase wrong as it was certainly a very long time ago but we kept the record of his purchase). So not only is has his batteries lasted so long, the unit he purchased is still working almost 8-years later. 

16 x 200ah batteries in series/parallel to 24v are the heart of my off grid solar system.

I'm running 240v power and 24v lighting off these batteries and believe me with 3 teenage kids and their electronic devices, induction stove, fridge, freezer, coffee machine, tv's etc. the system gets loaded up every day.

So the investment in batteries adds up to about Aud $12,000, and the investment in Infinitum desulfators equates to about Aud $600. It really is a no brainer, so much protection for so little outlay.

My batteries are in excellent condition, and continue to perform, we're in the middle of winter right now, with limited PV input hours. I fire up the backup generator about once a month, just to make sure it's ready if needed, apart from that, these batteries have no other input. 

Last winter we didn't need the generator, so far this winter we haven't needed it either. I'm confident the system is providing my family's needs and the desulfators are an integral part of that system.

The picture (right)  is of an original-equipment Volkswagen Transporter 2.5-litre turbo-diesel van battery, having been used daily for the last 8 years (mostly for short-journey work where the alternator rarely is able to fully recharge the battery). In our moderate UK climate, supplemented with occasional use of a smart-charger to help maintain its performance, it has lasted very well indeed.

But after 8 years of daily use, this original Varta 72Ah 700CCA battery was beginning to show reduced capacity and finally struggling a little to start the van. It had served me well, so I simply replaced it with a new one.

As an experiment, I removed the label and topped-up the fluid level of this original old "maintenance free" Varta battery with distilled water, and extensively charged / desulfated / reconditioned it using a smart-charger. It showed a little improvement - returning slightly more than 500CCA when tested.

The DHC battery tester I used here has settings to compensate for these different European test standards (EN, SAE, IEC, DIN and CA/MCA): The 500CCA reading taken before and 733CCA measurements taken after desulfating with the Infinitum were already compensated to correctly correspond directly to the original EN/SAE test standard of this 640CCA labelled battery. 

The performance (capacity) improvement of 733CCA SAE taken is therefore a genuine “like for like” comparison against the original 640CCA SAE stated capacity of this battery. The test was repeated several times over several days after charging/desulfating to verify the measurement, and re-checked using the alternative/labelled DIN test standard: It remains correct. 

The picture (left) shows this same battery after a further 4 weeks of then being left on trickle/pulse charge with the Ctek smart charger - but with your Infinitum desulfator then also added in parallel. Note the label showing the original 640A SAE cold-cranking capability of this battery... and the result of the digital test now showing an incredible 733CCA after desulfation with the infinitum - that's significantly better than new! Surprised? I was!

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.
