...good news for lamps and light bulbs, but not so good on batterys themselves.

After 8 years of owning a cruze with this system it has been so so on the bubs, it eats about 1-2 headlights per year but no other bulbs. Insofar as the battery, the OEM battery lasted 6 years. I too feared that the alternator would be hard on batteries but 6 years out of a battery these days isn't bad.
