The battery is only a year and a half old, but that is a good idea, I will take the battery to get it checked out. I heard batteries could last 2 months to 7 years. After market batteries are not as good as the original one that came with the car. The original lasted 8 years. This is the third battery in this car.

The voltage regulator is a bosch one, but for the cost of another new one I will purchase it. I thought that keeping an extra voltage regulator in the car is a good idea, I think I will do that.

Thanks

I will let you know what I find out.
