The use of an extension cord is not recommended. If you must
use an extension cord, please follow these guidelines:
• Ensure the pins on the extension cord plug match the Battery
Manager’s plug exactly (e.g. same number, size, shape, etc.).
• Ensure the extension cord is properly wired and is in good
electrical condition.
• Ensure the wire length and gauge correspond to the AC
ampere rating, as specified in the chart below:
