My 2012 MacBook Air (1.8Ghz i5 Ivy Bridge) gave the "service battery" warning, and the technician at a nearby authorized service center said that my battery no longer holds a long-enough charge due to wear and tear. That's all fine and dandy since it is to be expected after near-daily portable use. My question now is, can I still get 2-3 years' worth of use out of this model after opting for a new battery? My tasks aren't overly taxing - word processing, making presentations, watching offline or online videos, and I've yet to witness any slowdown despite updating OS X to El Capitan. I don't code and the only games I've played on my Air are the likes of Sudoku or Freecell - very non-intensive.
