(6) The hour meter has an internal battery
The engine monitor incorporates both a rechargeable internal battery as well as a
charging circuit.
While the generator is not in operation, the engine monitor will still indicate the hours
operated via its internal battery.
While the generator is in operation, the internal battery recharges.
When the generator remains unused for a long period of time, the battery will continue to
lose its charge. Once the charge is exhausted, the hour meter will not indicate hours, and
the battery will need to be recharged. From a completely exhausted state, recharging the
battery for 30 minutes will only result in a 30 minute charge to the battery.
However, if charged for 3 hours, the hour meter will indicate hours for more than 10 days
without another charge.
Please refer to the table below to see the relationship between battery time charging
versus length of indication by the hour meter.
