Mabel Gets A New Battery

I installed a hard start relay to see if this made any difference. The battery I was using was a Autocraft Silver 42-1 which is perfect for these cars, it has the protective cap over the positive terminal to keep from accidentally grounding out the battery if somebody is sitting in the back seat. Anyhow, I’d throw the charger on the battery for an hour or so and it’d be fine for a couple of weeks, then after she sat for a few days, I’d have the same issue. Voltage out of the battery without the car running was 10.8 volts, that’s low. Should be around 12.6. With the car running, I was getting right at 14 volts, so I knew the generator was working properly. That battery just wasn’t holding a charge like it should. I also tested for parasitic battery drain and everything checked out ok. The battery is almost 5 years old, time for a new one. This time, I decided to go with a Interstate MT-47. It got good reviews even though it cost a bit more compared to other batteries. It doesn’t have the protective cap over the positive terminal, but the case is built to prevent any accidental grounding. For added protection, you can always throw a piece of rubber, such as an old floor mat, over top of the battery as well. [Read more…]
