> I leave my lights on and kill my battery once every few months, so this is easily worth it for me I compulsively check to make sure my lights are turned off yet my battery still dies at least once a year because I don't regularly use my car, costing around $200 in on-site service and replacement per go. The smart shut-off feature is worth it to me - even if it's just to save time waiting around for someone to perform a replacement. The reduction in weight is a bonus as I have a small car with a fairly humble engine displacement.

One of the best tools I ever bought was a 6 amp battery charger. Plug it in, and in 20-30 minutes the battery has enough charge to start the engine, then you're good to go. This has saved me many, many hundreds of dollars, being late for work, etc. I also have a battery maintainer that keeps a battery sitting around charged up. The last thing is a battery shut-off switch that sits on the battery terminal. If you're going to leave the car a while, shut it off. It prevents the trickle going to keep the radio alive from killing the battery (which takes a week or two).
