Will My Battery Charge While Idling. Let us talk about whether car batteries are charged while idling. However if your electrical use load radio lights fan etc exceeds the amount of charge the battery is receiving from the alternator you will end up with a discharged battery at some point.
When the motorcycle is idling the alternator simply does not produce sufficient voltage to charge the battery. Then the alternator is producing AC current thereby charging the battery while your car is idling. The hybrid battery will get down to one bar and the triangle of death will come on while in drive idling like at a drive thru or car wash after about 5 minutes.
Sometimes its best to rev the engine and leave it revving for a little while too.
Many trucksvehicles pulling a trailer will provide a charge to the trailer battery while driving down the road. That is being turned by the engine crankshaft. You cant expect a bike to charge up a dead battery at idle. To maximize charging at idle turn off all accessories air conditioning and lights if possible to reduce stress on the alternator.
