Hello folks, ive recently taken a trip out to europe and have been driving my brothers car. In the past day and a half on the nav display there was a warning sign that stated for me to turn on the car or eveything would shut off in 3 mins(however car was on at the time).

Once i parked the car it wouldnt start but had enough battery to operate the doors windows and radio. I jumped the car and it started right away, and let it charge for about half hour. Once i shut the car off however it wouldnt start again.

Does this sound like a battery or alternator problem?

By the way the battery read about 10.6 volts while the car was running.

Thanks in advance everyone

While the car is running, the battery should read 14 volts+, it sounds like an alternator problem.
