battery charging

When I first fire up my Honda Genny I can hear the converter turn on. once I know longer hear it does that mean the batteries are charged
  • do you have a hydrometer to check the battery properly?.. All the stuff with voltage, amps and charge time are not accurate way to determine is the battery is properly charged or not.

    read this to find out a lot more about batteries, charging and generators and solar.
  • No, the converter is silent, you are probably just hearing the cooling fan in the converter which is thermostatically controlled.

    No.

    As the battery gets to 14.2+ volts, charge for an additional 60 minutes. This gets you to about 90%. 100% will take an additional 4 to 8 hours.

    If you have a fixed voltage converter you are slow charging at about 13.6 volts and you need 2 to 8 hours to get to 90%.
    thanks for the info

  • Maybe. What make converter is it? What's the battery voltage when the fan quits?
