A generator battery charger is unlike the battery chargers for automobiles. A generator battery charger is meant to maintain your battery charged by providing a precise "float" voltage to it.
This voltage shouldn’t be too low, or your battery may become undercharged, neither should it be too high because it will curtail its life.
Your business depends on having a dependable power source. Don't skip on this investment.
Many of our battery chargers use a ferroresonant transformer which, by its very nature, is self-regulating and completely lacking any complicated circuits that could potentially burn out. There are no tubes or fragile electronics to fall short or to cause radio frequency interference (RFI).
Voltage output to the batteries stays at a safe and constant DC level from full load to no load even if the AC power runs as high as 135 VAC or as low as 100 VAC. All workings are designed to operate safely and continuously in an different temperatures as high as 125° F.
Here are some features of our generator battery chargers.
• Stainless steel for corrosion resistance
• Ferroresonant transformer for reliability
• Fully automatic...nothing to adjust or set. (This means that the charger will never "drift" off voltage, damaging your battery, or leaving it undercharged.)
• DC output set at 2.33 volts per cell, the correct float voltage for lead acid batteries
• DC ammeter to indicate charge rate
• Combination switch; On/Off, pilot light, AC circuit breaker
• Cannot discharge battery during AC failure
• Sealed silicon diode, full wave, rectifier
• Isolated output - no direct AC to DC connection
