12V 3 Stage Battery Charger
Benefits:
1. Portability being small & lightweight
Battery chargers are smaller, lighter and more portable than conventional ones, now that they no longer have to rely on bulky and heavy transformers.
2. Saves on your power bill
Switchmode chargers now operate a efficiencies higher than 85% compared to the old designs that have typical efficiencies of 50% – 60%. Resulting in less heat generated and less electricity wasted.
3. Fuse protection
4. Maintains batteries & prevents damage
Batteries are never undercharged, preventing sulfation, which shortens the lifespan of batteries. Restore previously failed and junked batteries due to sulfation to optimum working condition, when used in parallel with our Desulfators.
5. Stable output voltage
These chargers also have stable output voltages, regardless of input AC fluctuations.
6. LED Charge Progress Indication
The 3-stage chargers have a fully-charged indicator. During charging, one LED is orange in colour, but will turn green when fully charged. It is a practice to always pay attention to the charging process when you’re using a relatively high-ampere charger as the batteries may overheat. If it does simply use a lower ampere charger or continue the charging process once the battery has cooled.
Applications:
Charges all forms of batteries used in vehicles, UPS or electrical equipment. Batteries include: lead acid batteries, SLA batteries, AGM (Absorbed Glass Mat) batteries, gel batteries, deep cycle batteries, maintenance-free batteries (dry batteries), calcium-calcium, calcium-silver, lead-calcium, or lead-antimony batteries.
The 3 Stages During Charging
The three stage charging process of the Infinitum 3-Stage Battery Charger is illustrated in the graph below and constitutes a Bulk Charge, Absorption Charge, and Float Charge.

Bulk Charge: The first stage of 3-stage battery charging. Current is sent to batteries at the maximum safe rate they will accept until voltage rises to near (80-90%) full charge level. Voltages at this stage typically range from 10.5 volts to 15 volts. There is no "correct" voltage for bulk charging, but there may be limits on the maximum current that the battery and/or wiring can take.
Absorption Charge: The 2nd stage of 3-stage battery charging. Voltage remains constant and current gradually tapers off as internal resistance increases during charging. It is during this stage that the charger puts out maximum voltage. Voltages at this stage are typically around 14.2 to 15.5 volts.
Float Charge: The 3rd stage of 3-stage battery charging. After batteries reach full charge, charging voltage is reduced to a lower level (typically 12.8 to 13.2) to reduce gassing and prolong battery life. This is often referred to as a maintenance or trickle charge, since it's main purpose is to keep an already charged battery from discharging. PWM, or "pulse width modulation" accomplishes the same thing. In PWM, the controller or charger senses tiny voltage drops in the battery and sends very short charging cycles (pulses) to the battery. This may occur several hundred times per minute. It is called "pulse width" because the width of the pulses may vary from a few microseconds to several seconds. Note that for long term float service, such as backup power systems that are seldom discharged, the float voltage should be around 13.02 to 13.20 volts.
Available Models
The 3 stage chargers come in 5A, 8A and 12A models.
There is a 10% rule when it comes to battery charging, for example, a 50 Ah battery should be charged at 5A, and a 120 Ah battery at 120A.

12V Battery Desulfator Optimizer 25R Series
The 25R & 40R Series Infinitum Desulfators are for industrial use and reconditioning batteries. They are exactly the same as the regular 12V Desulfator except they do not have a shut-off feature and works within a range of 6V – 12V.
The 40R series has a higher pulse for batteries 70Ah and more. All our Desulfators work regardless of the Ah rating of a battery. However with the 40R, the process is speeded up.

"
“I ran this desulfator unit on the battery in my 7 year old booster pack that would never hold a charge over 20% and voltage read 4.2 volts. I didn’t think it would work but it is now reading 12.5v and says 85% after 3 days trickle charging with the desulfator connected.”
Jeremy Shaffer (YouTube Channel: Tooextrememx’s) Quad & Motorcycle Enthusiast, NY, USA
"I now have a hassle-free maintenance for my solar and wind power batteries. I have been a repeat customer and will continue to do so."
Greg Mason Rimfire Technologies, Washington, USA
"I am very satisfied with the Infinitum Desulfators I bought. I have recovered one almost dead battery. After almost a year later, I am still using the same battery in my motorhome Photovoltaic system. Its perfect, keeping the charge pretty well."
Jorge Monteiro Lagos, Portugal
"My 18 month old 600CCA rated Duralast Battery had been left uncharged in my car since I installed it. Just before using your desulfator, it measured 4.6V. After charging it overnight with a trickle charger and your desulfator and 1 week of occasional driving, the battery then measured 12.42V and 1376 CCA. I had the battery tested with a digital load tester at the Advance Auto Parts in Orange, Massachusetts, even they were astounded by the results!"
Ted Athol, MA, United States
"I use a 12V battery to power the trolling motor for my kayak. I decided to buy the Infinitum Desulfator to salvage a 3-year old sealed lead acid battery which was completely "dead". To my surprise, the battery came back to life!"
Gerald Khoo Eco-Sports, Kuala Lumpur, Malaysia
"I installed a very weak battery which I collected from the junk pile of a tyre shop in Petaling Jaya into my car. My casual observations told me the battery is as good as new after 1 month of the Infinitum Desulfator use. Measuring the conductance of the battery using an analyzer, confirmed that the battery has been revived from junk. It is miraculous."
Ir. Chia Engineer, Petaling Jaya, Malaysia
"I have been driving around with a revived “dead battery” for the past 5 months. I can’t believe that I have been throwing away weak batteries in the past."
Anthony Charles Chemical Engineer
"I was an absolute non-believer until I actually measured the Ah rating of my car battery. It went up 20%, two weeks after I installed the Infinitum Desulfator."
John Wong Electrical Engineer
"One reason your battery desulfphators appeal to me is the sealed epoxy encapsulation, protecting it from the wet and salty air of the marine environment."
Ken Lessin Marine electrician, Caribbean
"I am stoked, it has not only saved me A$4500 on a (fork lift) battery pack but it costs much less to recharge as well so I save on my power bill!"
Tony Castleman Qualified mechanic of 25 years North Shore, Victoria, Australia
"My 3-year-old battery went from a nearly dead battery to cranking a 262 cu in. engine like a brand new battery."
Joel Grant Auto enthusiast Carmel, Indiana, USA
"We have found the LED displays on the Desulfator units to be particularly useful in monitoring the battery voltage of seldom used equipment with illumination of a red LED giving us a prompt that voltage has fallen to a level which requires the vehicle to be restarted or recharged to maintain reliability."
David McNamara Queensland, Australia
