Low battery voltage
When I checked the battery voltage on my car with my digital meter, it registered only 11.5 volts. This measurement was taken with the car's engine turned off. When the car is running the reading is right around 13 volts which I assume is normal hen it is being charged by the alternator. But as soon as you turn off the engine, the voltage starts to drop when you look at it with the multi-meter.
Right now I am charging it up with my battery charger. Once it is fully charged, I will continue to keep an eye on it. But I am wondering if there is enough parasitic drain from the electronic components to discharge a battery if the car sits idle for 2-3 days?
