Hi can somebody tell me what a fiat ducato 2006 alternator charging amp output to a leisure battery could be at maximum?
Alternator amperage output
- Thread starter freeflow
- Start date
According to a google search, the alternator has a 180A capacity. However you would not see that much charging the leisure battery, The actual current output from an alternator when is determined by the load resistance and the voltage limiter.
Most auxiliary battery and fridge circuits are fused to 20A each. The actual current fed to the caravan just like above will dependent on the difference between the batteries standing voltage and alternators voltage regulation output and the resistance of the conductors between the leisure battery and the batteries internal resistance.
In practice this usually means the typical charging current available for a caravan/motorhome leisure battery is unlikely to exceed about 10 -15A when the batterie is discharged, and reduce down to as the charge increases.
