When I went for oil change at Wal-Mart, they told me that it time to change the battery, they have showed me results. I asked them how long I can run without changing it, they told you can run for a month or like that but not sure!(I purchased my car last year in November, they the previous owner told me that she replaced a new battery! But no receipts or details etc.) Here are the results for battery checkup.
Voltage 12.70 volts
Measured 523 CCA
Rated 640 CCA
Temperature 84oF
Test Code: 9986G0209NG
Average life in area 65 MO

Now my question is that, is it necessary to change the battery? How long I can run without changing it (I commute 7-8 miles daily) Is there any specific observations, where I can determine that now I have to change it. Like that.

Thanks

Your only down like 117 cold cranking amp's it look's like there is still some life left there. AS far as it being a new battery when you bought the car who knows about that people forget if they changed the battery or not. The battery has a date code somewhere to tell you when it was built. AS far as how long the battery will last I haven't had much luck even predicting that with my own batteries there is no telling. Sometimes the batteries will give a warning like start to slow crank the engine other time's they will just be totally dead no dash light's no crank. Take it to a auto part's store and get a second opinion on if it's good or bad. Then you will have to decide how lucky you feel on how long the battery will last if it test's bad.
