bsavall said:I hate to bring this up, but how does an owner determine if they got a bad battery? Did Nissan have a bad batch of batteries and some of us got the lemons? Could the large discrepancy between different owners be less about driving habits, and more about quality control issues with the batteries? How would we know?
The dealership would know exactly what the capacity of your battery is, since the owner is probably a rebublican you dont want to trust them too much.
There probably is a variation in battery quality, some of the chinese manufacturers are reputed to have a variation of 10%. Every cell undergo "formating" charge/discharge cycles at the factory as part of the manufacturing process, hopefully every substandard cell would be discarded.. or perhaps graded and binned accordingly, for later use in repairing batteries.
To test your battery at home, just run it around a predetermined course, but make sure you end up at the start point so that elevation changes and winds cancel out.. run a continuous loop around you house, about 3-4 miles away from it. That way you have range to get back home when the warnings come on.
I'm lazy, I would just prop up the front of the car on jack stands and run the motor until the battery conks out
