I didn't know he didn't have a Battery Tender of his own, so the car sat without anything helping keep it charged up.
Yesterday when I went to collect the car, it wouldn't start. We jumped it, and it started normally, but after turning it off an hour or so later, it wouldn't start again. Thinking the battery was just extra-low, we left it on a charger all night. Today, same issue - no juice. So now I have a brand new battery, which I will monitor the performance of.
The question for you experts is this: What's the average lifespan of a battery? I live in the Pacific Northwest, where temperatures rarely get too hot or cold, and batteries in my other vehicles seem to never fail.
What's your experience?

Battery life is a totally open ended question. Batteries die because of how they have been used, the climate they operate in, parasitic drains of the car, condition of the car's charging system, etc. They can also suddenly succumb to internal shorts or component failures, sulphation, etc. We have seen them live happily for 12 years, or die in 2 years.
