[quote=Anonymous][quote=Anonymous][quote=Anonymous]This is op, forgot to up update that it was the battery problem. Once I got a new battery, everything goes well. But one thing was weird that they check my old battery was in healthy condition, but battery was really low, like 10 only. I don’t have any headlight or interior lights on the day before, not sure what things exhaust all power in the battery. I hope it is the generator problem.

I got rid of my previous car because of generator problem, and the car completely relied on battery to function, and power exhausted in a day or two. It had too many mileages, so I decided to get rid of it, not worth to repair it.

I don’t drive my car often these days because of working from home, but I drive about 2.5 miles in the morning, and 2.5 miles in the afternoon for drop off/ pick up kid. If it is generator problem, how long will it take for my car to die again?[/quote]

I meant the alternator.[/quote]

It's very easy to check. Get one of these volt meters that goes into your cig lighter:

https://www.amazon.com/Zeltauto-Cigarette-Lighter-Digital-Voltmeter/dp/B00VL9JZ0K

It should read at least 13.5 volts with the car idling and electrical things like the headlights and stereo turned off. Turning these things on, it should still read above 13 volts. Driving around town should read 14-14.5 volts.

If it falls below 13 volts, you should get the alternator checked out. [/quote]
