2002 996 C4S battery problem

[Gary S K Lee]

This morning when i tried to start my car it has no battery to start. I tried to jump start with another car it started but then the battery died shortly after driving for like 5 mins. Does it mean the battery can't hold charge or the alternator is not working at all?? Should there be any warning lights popping out if the alternator is not working?? I already ordered a new battery i hope it will solve the problem.

thanks

Does sound like a battery but hard to say without load testing it. How old is the battery? If you are going to put in a new battery anyway (sounds like you are), just make sure the new battery is charged up. Then once the engine is running, just pay attention to the voltmeter gauge. It should read 13.5v - 14.5v all the time when you are driving even with all accessories ON.

Great. Now just keep an eye on the voltmeter to make sure you're seeing 13.5-14.5v whenever the engine is running, then you should be fine.
