Infinitum Desulfator Installation & Setup


Sulfation is the lead sulfate crystal build up on lead plates of batteries, resulting in less usable active material, essential to battery lifespan.

Optimises efficient storage capacity

Green LED – Battery voltage is above 12.5V. The Green LED must be on when the engine is running.

Red LED – Battery voltage is below 11V. You should never see this when the engine is running! If your engine is running and no LEDs are illuminated, either the unit has failed (which is unlikely) or your alternator has failed. 
When you crank the car, you may notice the Red LED illuminated for a short while, then the Green LED lights up. This is normal. During cranking, current is drawn out of the battery, causing a drop in voltage. At this moment, the Red LED indicates the voltage drop. After the alternator kicks in, the Green LED will illuminate, confirming that the voltage is above 12.5V.

Installation In 3 Simple Steps:

External Desulfator Installation

All Infinitum desulfator models can be installed paralleled with an appropriate external charger.

Reconditioning two or more batteries: For example, when using the 12V desulfator, two or more batteries can be set in series and be reconditioned as long as the voltage adds up to 12V.

Installing The Infinitum Desulfator On Multiple Batteries

Installing Multiple Batteries In Series

Both illustrations above are typical setups for golf carts or fork lift batteries, where six 6V or 8V batteries are lined up in a serial connection to produce a total voltage of 36V and 48V respectively. The Infinitum Desulfator can be installed in parallel on more than one battery.

Figure 3
In Figure 3, we see how an Infinitum Desulfator is installed in parallel to a configuration of six 2V batteries in series often found in UPS (Uninterruptible Power Supply) batteries or solar and wind battery banks.
In Figure 4, the Infinitum Desulfators can be installed on individual batteries and charged together. In this setup, all four 12V batteries in series would be charged with a 48V charger in a parallel connection. Similarly, the desulfators will work just the same should there be more or fewer batteries in the serial setup, just as long as they are charged with a correlated volt rated charger.

Installing Multiple Batteries In Parallel

Dedicated desulfators are installed on each battery in this parallel setup.
The desulfators installed on a battery bank with batteries setup both in parallel and in series.


The length of each cable measures 10.5 inches (270mm) providing a span of 21 inches in both directions. The length of the cables can be increased by soldering on similar or thicker cables.
The combination of battery setups are virtually limitless, as long as the total voltage of multiple batteries matches the voltage of the desulfator. The rule of thumb being, the fewer batteries a desulfator reconditions the greater the efficacy.

Infinitum Desulfators are designed to work when the batteries are in a state of being charged. This unique shut-off feature initiates when the battery voltage drops to about 12.5V. This is to prevent unnecessary battery drainage, even though the power consumed is less than 0.5W. So for any of these configurations above to work, they would need to be in a state of charge.
