FAQS



Q:What is Microprocessor Controlled Charging?


A microprocessor controlled battery charger is designed to provide fast, safe and efficient charging to a wide variety of battery types and sizes. Advanced microprocessor controlled algorithms monitor the charging process to avoid battery damage caused by overcharging. Simply put, the charger collects information from the battery and adjusts the charge current and voltage based on this information. This allows the battery to be charged quickly, correctly, and completely when using a microprocessor controlled battery charger. Because of this, fast charging does not have negative effects on the capacity of the battery and on battery cycle-life. The multi-phase charging process ensures that each battery gets the power it needs in a manner that is best for the health of the battery ensuring that all of the energy is properly absorbed by the battery whether it’s a Conventional, AGM, Gel Cell, Marine or Deep Cycle battery. Microprocessor controlled battery chargers can remain connected to the battery indefinitely and will not overcharge or damage it. Microprocessor controlled battery chargers are faster, safer and certainly more efficient than "old school" transformer type battery chargers.


Q:What is Automatic Charging?


When an automatic charge is performed, the charger stops charging and switches to the Maintain Mode (Float-Mode Monitoring) automatically after the battery is fully charged. Automatic chargers are more forgiving on the battery than manual chargers but are not designed for indefinite or maintenance use. Automatic chargers use a cycling process (see Maintain Mode) to prevent overcharging the battery.


Q: What is Maintain Mode?


When the CHARGED LED is lit; the charger has started Maintain Mode. In this mode, the charger keeps the battery fully charged by delivering a small current when necessary. If the battery voltage drops below a preset level, the charger will go back in to Charge Mode until the battery voltage returns to the full charge level, which at this point the charger will return to Maintain Mode. The charger automatically switches between Charge Mode and Maintain Mode as necessary. The CHARGED LED will cycle on when the battery is at full charge and off when the voltage drops below a preset level and the charger goes into Charge Mode. The cycle will continue, and the CHARGED LED will stay on for longer periods of time as the battery becomes more fully charged. The voltage is maintained at a level determined by the BATTERY TYPE selected.


Q:When should I use a 2-amp, 10-amp, 12-amp, or 15-amp charge rate?


This depends on how fast you want to charge your battery and the size of the actual battery you are charging. The higher the amp setting, the faster your battery will charge. For smaller batteries like lawn/tractors and motorcycles, we suggest a 2-amp charge rate, as higher charge rates may create a dangerous condition. Check your battery specifications for the charge rate.


Q:Why doesn't my automatic battery charger shut off in the 2-amp position when charging my vehicle or deep-cycle battery?


The 2-amp charge rate is intended for small batteries such as motorcycles, snowmobiles and lawn garden tractors. Consequently, when trying to charge a larger battery at that rate, it will take a very long time and the battery may discharge at a greater rate than the 2-amp charge can provide. It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher. However, check you battery specifications for the proper charge rate.


Q: Why don't I get sparks when I touch the battery clips together, creating a short?


With electronic short-circuit protection, the battery charger must be able to measure a battery's voltage before it turns on. There is no output power in the clips until they are hooked up to a lead-acid battery.


Q:How long can I leave my charger connected to my battery?


The type of charger you are using more accurately determines this, but generally your battery charger is safe to leave powered up and connected to your battery until the battery has reached a full charge. Manual chargers should be removed as soon as the battery has reached a full charge. These chargers will not cycle or shut down by themselves. They will continue to put a current through the battery until they are disconnected. The use of a hydrometer or voltmeter to monitor state of charge is recommended for use with manual battery chargers.


Automatic chargers are more forgiving on your battery than manual chargers, but they are not designed for indefinite use. They utilize a cycling process, as described above, to prevent overcharging of the battery. The only charger recommended for extended or storage application is the 1.5 amp 12-volt charger specifically designed for long term, slow trickle charging/maintenance applications. However, problems with the battery, electrical problems in the vehicle, improper connections or other unanticipated conditions could cause excessive voltage draws. As such, occasionally monitoring the battery and the charging process is recommended.


Q:How do I tell what type of battery I have; Flooded, AGM or Gel? 


Flooded or Wet Cell batteries are the most common lead-acid battery type in use today. They usually are not sealed and electrolyte can be added through holes in the top casing of the battery. Gel Cell batteries are sealed and cannot be re-filled with electrolyte. Therefore they have a smooth top with no access holes. AGM (Absorbed Glass Mat) batteries are the latest step in the evolution of lead-acid batteries. They are sealed like Gel Cell batteries but are smaller and can be recognized by their compact size.


Q:What is the correct charging voltage for my battery?


That depends on the battery. While most of today’s automotive and marine batteries are 12 volt, some motorcycle and lawn tractor batteries are 6 volt. Check the battery and the owner’s manual of the vehicle the battery came out of for the correct voltage. The value of the charge rate voltage is determined by the battery manufacturer. Deviating from the recommended values will under or overcharge the battery – both of which will reduce the battery’s life and performance.


Q: How can I tell if my battery needs to be replaced?


If your battery won’t accept a charge or won’t stay charged as long as it used to, replace it.


Q: Why is the fan on all of the time?


It is normal for the fan to be on all the time in order to keep the transformer and electrical circuitry cool during normal charger use. Keep the area near the charger clear of obstructions to allow the fan to operate efficiently.
