I have a Sonnenschein battery in Crashy that was manufactured in 2001, was used for some testing with the mobile robots I used to work with, spent about 7 years being used very intermittently on my Gravely walk behind tractor (which was used in the spring for rototilling and once in a while in the winter for snow blowing) and has now been in Crashy since February of 2011.

The Yaris is a bit tougher on batteries that most other cars, as it has a high static current draw (over 100 mA), which means that in a week or two of not using the car you have significantly drained the battery. So, Yaris that are driven 365 days a year will see longer battery life than Yaris that are driven intermittently.

Very interesting. If I was to go out of town for 1-2 weeks (or even MUCH longer) and not bring my Yaris with me (Yaris would be 'alone' ), what would be the best (safest and most effective) way to preserve the charge in the battery?
