How long would you guys wait before getting a new battery given these readings?

Hmm, I've put it off for a while now, not sure if I should just have the dealer do it (CAD446/USD328) or save $ diy? Is the savings worth it?

AutoZone has the battery (H6-AGM) for $174 and here's a coupon for $15 off. Then buy the Carly app for $60 and their adapter for another $70. You'll save a few bucks this time, a bunch next time since you only need to buy the app and adapter once, and you'll get to code all sorts of neat functions in your car with the app now as well.
