Champion Home Backup Generators have the most powerful starting system in the industry. Two automotive-type batteries connected in series provide 24 volts of power—twice the starting voltage of other brands. Many large commercial vehicles (trucks, buses, and some RVs) use at 24-volt starting system. The Champion 24-volt starter motor turns at twice the speed of a 12-volt starter for better fuel delivery and ignition in any weather including extreme cold climates.
Unlike other brands, Champion designed their Home Standby Generators for Severe Cold in severe cold down to -22 degrees Fahrenheit without the need for warmers or other cold-weather addons. As temperatures fall below zero, the available power in a battery also drops. Connecting two batteries in a 24-volt system provides double the available power for more reliable cold-weather starts. The last thing anyone needs when the power goes out at 20 below is a standby generator that won’t turn over because the battery is cold.
Installation requires two Group U1 12-Volt Batteries with a minimum rating of 350 Cold Cranking Amps connected in series for a total of 24-volts.
