I've done several, and it did. Make sure throttling is disabled (Settings, search for Battery Health); in my experience the OS doesn't do that on its own, presumably relying on the playbook they give their support techs to cover that. It also doesn't hurt to do a "battery calibration" process like the one found at https://help.ifixit.com/article/265-battery-calibration - I don't know that I've seen a huge difference from that, but I always do it, so I wouldn't really be able to say that it's not necessary even if it isn't.
