Then see if it starts up quicker.

. Fully charged battery should be 126 with engine off. However the battery can be charged also with higher voltages for fast charge which is not implemented in automotive alternator so it should output the float charging voltage. 24V LiFePO4 Battery Voltage Chart.

The voltage will fluctuate depending on the outside temperature. This voltage range means the battery is in good condition for starting the vehicle. If it reads 124 volts this means the battery is operating at only 75 percent capacity.

Usual average cranking voltage should be 108V. At rest engine off. If your car battery voltage is discharged or has less than 124 volts the power decreases dramatically.

I measured the voltage across my battery using a voltmeter directly connected to the battery terminals. 24V lithium iron phosphate batteries are another popular option for solar power projects. When the Car Is Running.
