How To Test If A Desulfator Is Really Working

Testing the efficacy of your desulfator:

The best way to test the efficacy of our desulfators is to have the battery tested for CCA (Cold Cranking Amps) and milli Ohms (mΩ) before installation. You can either use a multimeter or a digital battery analyzer. Over time, you will notice an increase in the CCAs and a drop in the Ohms.

How long does it take to fully desulfate a battery?

  • 2 to 3 weeks when installed in a vehicle with daily city driving.
  • 2 to 3 days when installed with an external charger
  • 1 to 2 weeks with a solar or wind power

The above estimated durations are influenced by the following variables:

  • Level of sulfation
    A brand new battery will usually have a single digit milliohm reading while a heavily sulfated battery can have an Ohm reading up to a couple of hundred milliohms.
  • Amp hour rating of the battery
    Infinitum Desulfators are unique in that they are able to recondition even large forklift batteries without an issue. For road vehicles, 2 to 3 weeks is more than sufficient to fully desulfate a battery, the rest of the time, the desulfators work to prevent the accumulation of sulfation.
  • Duration of the charge
    The amount of effective sun and wind conditions affect the level of charge provided in a solar and wind power setup.

Battery Tip: When using an external charger, ensure that the charging amps on the charger is at least 10% of the battery’s Amp Hour (Ah) rating.

Why CCAs & Ohms?

The actual reading of a battery’s health is in its CCA (Cold Cranking Amps) or Ohms.

These two readings will contrast each other. CCAs measures the ability of a battery to start an engine. When sulfation occurs the build up of sulfate crystals will increase the resistance (Ohm) in the battery which in turn reduces the CCA.

Voltage readings indicate the state of charge for a battery, so in most cases, the voltage reading will remain high whenever the battery is fully charged. After all, you want to know a battery’s capacity to crank an engine, not its state of charge. So voltage is not always a true indication of the battery’s condition. 

What if I don’t see any results? Does that mean that the desulfator isn’t working?

There are instances even desulfators cannot recover because the failure or poor condition of the battery is not related to sulfation such as:

  • Natural wear & tear: old age, separators between plates decay, plate connectors corrode, etc.
  • Abuse – filling tap water instead of distilled water into the batteries.
  • Physical damage – any strong impact or dropping a battery
  • Lack of Maintenance – not filling water into the batteries, loose connectors.
  • Aging – batteries that are too aged will lose active material.
  • Crystallization of Lead Sulfate – 84% of batteries fail due to this (Battery Council International).

It can be that you are also using an amp rated charger that is too low

As the name suggests, desulfators can only recover sulfated batteries. Though there are several conditions where batteries cannot be recovered, 84% of premature battery failure is still due to sulfation, so it still makes sense to own an Infinitum desulfator as you can always use it on other batteries if one is unrecoverable. And due to the robust nature of the Infinitum, you can expect to reuse the device over several batteries throughout its service life.
