Yes, as far as I know, for Ti-book. > if I get a new one, will it have a higher initial capacity then my >current battery once had? Yes, almost certainly. I replaced my original Ti-500 battery after 2 years ("end of life for a Li-ion battery") with a new one, which had a larger storage capacity. >3) Which steps do I need to take to ensure maximum battery life? From memory: allow the new battery to drain completely. Recharge fully. Repeat every 3 months. There are articles in the Apple knowledge base about this (search, patiently at: http://kbase.info.apple.com/) >4) What does a new battery cost (in euro's)? I think my new Ti battery was about $120.
