Noticed

 Have sort of worked out what they mean by a battery will go so far on a full charge.
I have never gone the distance in one ride or even in a couple. So, I assume when it says a battery will do 40km or 60km it means that it will do that distance before a new battery is required?

Battery seems to keep it's charge longer when it is new. After only a couple months it loses it quickly.
Also it seems to stay on full charge for some distance but once it comes down from 6 bars it loses power quickly. I would have at least gone up to Unley on 5 bars when the battery was new but now I wont.  From my place to Goodwood road it drops dramatically and going over to Unley is at least 3 times the distance.
