I have a battery tender and would hook it up if I went more than about 5 days without driving the car.

I have 17,500 miles on the car in 3 years and 8 months.
Yea the aH reading is about a 1/3 of the oem battery so short distance, 1 or 2 times a week definitely affected the life.

Our cars don't charge the battery until the engine is properly warmed up. So short distance driving doesn't charge the battery.
