Yesterday I had to go jump-start Andrea’s car again, this time in the pouring rain. Why is it the car won’t start only on cold or wet days? This time, I listened to some advice from co-workers, who suggested the battery is probably on the way out. I took it by Auto Zone this morning. They hooked it up to a battery tester and said they think it’s fine, but just needs to be charged. They offered to sell me a battery if I insisted, but said they didn’t think I needed one.
It makes me wonder, what accessories in the Saab are using so much power that the battery has gotten too low to start the car twice in the last month? Instead of buying a new battery, I bought a home charger and an emergency jump-starter, both on sale for 50% off. When I got the car home today and hooked it up to the charger, the battery was at 80%, and charged to 100% at the medium setting in about twenty minutes.
Andrea just had the idea that the broken antenna could be draining the battery if the motor is continuously trying to raise or lower it. I’ll have to replace it and see if that fixes the problem.
