My suggestion is you to Use blevo to double-check.. see pic.

Just a question about how to handle the battery right after the purchase. My dealer didn't really say anything about it, and I forgot to ask, but is there an instruction from Specialized on how to handle the battery?
I think of things like full charge and full discharge as first cycle, or is this not relevant?

How can you be sure the bug isn't in the re-installed app?

That's another very good possibility and you're right.....I can't be sure

I’ve just downloaded Blevo which is stating my battery is 390wh @100% charge. Being the 2017 it’s the 460wa battery.....
That's 84%. we have to accept that batteries have a lifecycle; that's it. And are expensive
.I'd like someone using them long term 2 years or more could tell us about the experience. So when to change? 75%? 60%? So range is affected of course and we will reach a range where we would need to replace. Maybe 2-3 years? 4 years? ( In normal use (6hrs week)

Very interesting link.
I take it from this that there is an advantage to half charging your battery after a ride, storing it in the refrigerator, and then top up charging on the morning of your ride? Particularly over summer in places where it gets hot.
There is probably also an advantage to having 2 batteries and only discharging each in the 80% to 30% range (giving 2 x 50%, equivalent to 100% out of one battery)?
Yes, though if you are in the UK like me I am not sure youneed to worry about using the fridge - it is not normally that hot here! My modelling lipos have lasted 2-3 years in general use and are always stored at 3.8V/cell; it definitely prolongs life over charging to full after every use.
In theory maybe, but remember without some additional detective work we do not know how the BMS is treating the battery in terms of the points it registers as "fully charged" and "flat". If it is like many consumer electronic devices it is likely to be stopping the charge at around 90% capacity, and stopping discharge at ~30% anyway. This should be something we can check with a voltmeter easy enough; I will see if I can do this with my Dad's pack at the w/e when I go up to visit him (I don't yet have an eMTB of my own).
In practice I think you are probably better having a single battery, running it until it no longer has sufficient capacity/power delivery to be usable, then buying another. Remember both packs will be ageing over time from the moment they are manufactured anyway, so running one into the ground then buying another fresh one probably makes more sense unless you regularly do longer "2 battery" rides.
UPDATE: with a happy ending...
So to cut a very long story short, as part of testing power outputs of different 1.3 motors, my LBS loaded 10.22.x on my battery and then upgraded it back to 10.23.x (which is where it was originally at).
Now my battery health is reporting it is back to 100% and holding 504Wh’s!
In BLEVO also?
Yep - I was sceptical at first but MC and BLEvo still showing it at 100% / 504Wh.... weird!
Yep, not very consistent. But...

I've used my Kenevo twice, accumulating less than 40km albeit on steep climbs. Battery health now at 90%. I've read somewhere here that this may be inaccurate if < 3 charges and discharges so will use again this weekend and take another sample but it's worrying me at the moment. Nothing that, to my knowledge after some research and advice, the battery / motor has been through should have caused this so very anxious to see how this will develop!
