Well good to know about the new battery being tested good.
You mention that one day it starts fine the next acts up. When you go to start it, do you then ride it, or is like you go out and start it, not do no riding and then do it again.
If you do start it and go for a ride, what would be the average miles on the ride.
Reason asking, if you are just doing short bar hops, even with the tender on (depending on the model and size), it may not be getting a full charge while riding and leaving you short.
Maybe when it does not want to start again, check the voltage with a good multi meter, see what the voltage is before cranking, what it is when trying to start.
You may want to also check the alternator and VR. Do a search on here to find a good DIY and sticky that breaks down how to do so.
Just a few items for thought to look into. May very well be the EHC, but I sure would go through everything else first and maybe a second time. Oh and without knowing your mechanic and how they are testing the battery, may want to just make sure that it is being properly load tested. Many of mechanic will just through a simple test on that will show voltage and some load, but may still miss like and intercell short, sulfication, and other things that are not so easy to see. Got a battery mart near you, they usual can do a full load-battery check. What type of battery anyway AGM, Lead, LiOn?
Good luck and do not let it beat you, worse case you can do a change out to PDM, WP or go old school and back to basic.
