I usually drive only like 3-5 miles a day. Then 1-3 days no driving. Once a week,maybe 10 miles a few days. My car just passed the 40K mile mark last moth. It is a 2006, I bought it new. So that is how little I drive. So just over 3K miles a year. I have no extras in the car, except the security system. Nothing like a monster sound system or added navigation crap sucking up power. So it is just regular items that came with the car. Here in south Fla. the heat eats up batteries, I know that, this and my other battery I had are both sealed units. So I cant check the water in the cells.

The one that came with the car, an AC Delco was a 30 month battery. It died right on time, 28 months. Then got my first new battery for it, that lasted 2-3 years, suppose to be a 5 year battery, then got the MAXX Wal-Mart battery, 16 months ago, worked great, till this morning. Now I have a new MAXX one, 650 CCA, so I am not pulling a lot from it, other than starting it. It is all city driving. 100%.
