Dead Interstate Battery

Schumacher SSC-1000A Battery ChargerThe Interstate MT-47 battery in the Bavaria decided it didn’t want to hold a charge anymore. The specific gravity of each cell was reading < 1.1. I spent an hour looking for the receipt and couldn’t find it. The battery has a 75 month warranty but I was just going to buy a new one.

Luckily, the Interstate delivery guy was at the garage when I went to pick up the battery, and he read the date code off the side of the battery which was January 2003. The dealers have a chart for pro-rating the warranty and it came out to $1.52 per month – the new battery cost me $72.96, instead of $109.

Battery charger connections

In the mean time, I had ordered a Schumacher SSC-1000A Battery Charger from Amazon for $34. It seemed like a good deal. The charger gives a percentage value of full charge and voltage when the terminals are first connected and then can charge at 2, 6 or 10 amps. There was also switching for regular Lead acid batteries, deep cycle and gel cell batteries.

Shorted wrench

While trying to adjust the positive cable from the car to the battery (ironically, so I could fit the orange positive terminal cover), I didn’t notice that the ground cable had fallen onto the negative terminal on the battery. The result was a big spark, a hole blown in the cover of a relay box and a melted socket wrench extension.
