Note from Infinitum: We received this feedback from a customer from Australia who revived his deep cycle marine battery from the dump to a fully functioning battery! We particularly loved the candid way it was written and left it completely unedited:
We recently bought one of your 12V Infinitum Desulphators, intended for a former UK Colleague, but owing to the problems posting it to him in time for Christmas, we thought we’d give it a go ourselves!
ALWAYS a bit suspicious of much-vaunted claims, so to be honest we were not expecting anything really spectacular. Thought I’d try it out on an old (and rather abused) marine engine start battery which had been “living outdoors” for some time.
Although the electrolyte levels were OK, the battery wouldn’t accept ANY (and I really DO mean ANY) charge whatsoever, such that I had to keep it on trickle charge just to get the desulphator to work! Thought this would be a useful test of any capability, so left the charger and desulphator connected for two weeks, desulphating away happily.
At the end of the fortnight, disconnected the charger, and, surprise, the little green light stayed on – and kept staying on for a further 16 days! Upshot is we now have a seemingly fully functional battery that charges well (accepts a high charge current without overheating), retains the charge (for weeks), and can easily start a 4 litre marine diesel – and remember this battery was effectively “scrap”!
The Infinitum gadget is currently desulphating:
The Isuzu’s a 24 volt set up, and we’ll be buying your 24 volt version soon – and leaving it permanently connected to the engine start battery set.
We would be more than happy to let any other future customers know just how good this little gadget is – and please feel free to include this e-mail in your Customer Comments section!
Thanking you again for what is a surprisingly very effective little “box of tricks”
Best regards from us both,

Over the years, calcium has been added to lead plates to improve grid strength and conductivity, and reduce gassing and its self-discharge rate. With this, the low-maintenance or maintenance-free battery was introduced. However, the alloy plate is still consists of more than 99% lead. Whether the battery is calcium-calcium, calcium-silver, lead-calcium, or lead-antimony, it is still essentially a lead acid battery and suffers premature failure from sulfation just like any other lead acid battery. The Infinitum Desulfator reverses and prevents sulfation, typically restoring batteries to the best possible condition, maximizing its life span up to 3 times.
An excerp from Popular Mechanics:
HOW IT WORKS: MAINTENANCE-FREE BATTERIES
Like many things in life, the term “maintenance-free” is only partially true. Lead-acid batteries normally consume some of the water in their dilute sulfuric acid electrolyte during a normal charge-discharge cycle. It actually electrolyzes into hydrogen and oxygen and escapes as gas. So adding water periodically is necessary to keep the plates flooded. Maintenance-free batteries use a calcium alloy of lead instead of an antimony alloy, which reduces the amount of electrolysis.
In addition, the amount of free-standing electrolyte above the plates is designed to be much higher in a new maintenance-free battery. This means that there’s enough electrolyte to keep the plates covered even after a few seasons of normal use. So, during the battery’s normal service life there should be no need to add water. Any abnormal electrical system condition or high ambient temperatures may boil off more than the normal amount of water, however. Adding water may extend the service life of these supposedly maintenance-free batteries.
