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.
