AOA
I faced strange issue today.
washed my civic and went for drive (didn't wash engine bay and bonnet was closed)...
drove about 40 kilometers in hot weather and took break near grocery store....
I tried to start my car after 5 minutes break but it didnt start...Felt as if battery is trying to start the engine has less power
The battery tried to start the car but failed .. dashboard lights and sound system was working properly... Had to jumpstart using another car's battery
Reached home safely and parked it in garage... same issue car was not able to start
I tested again after 3 hours and car starts normal now....Everything is back to normal but I want to know the main reason of the issue in order to avoid such issues in future...
battery voltage when car is powered of is 12.25 volts... and when i start the car, it reads 13.7 volts
