How can my battery be bad if when I had it out and it started my other bike no issues ?
A battery that can start my four cylinder car can be "bad" if I rely on it to start my v8 truck. It's all relative. How did the guy test the battery? Load test? Algorithm voodoo (which can be very accurate)? Did we figure out where this bike is yet? A competent troubleshooter that has been through this before can probably get to the heart of your problems in under an hour.
First off, your definition of "no issues" may be a be of an overstatement:
Hardly sounds like "no issues". A larger capacity battery should have started your smaller S40 pronto on the first try, and not have to require 7 cranks.
A battery has two functions: storing energy and releasing it.
You said you just charged up your motorcycle battery last night:
Your battery is holding a short-term charge and is able to release that energy because it is topped up. However, whether it is capable of storing that energy long-term is in doubt.
Had a user on here a few months ago wonder why his battery kept dying on the road. It cranked his motorcycle fine first thing, good voltage, etc. Turns out he was plugging his battery into a tender every night, so of course, when he unplugged it and fired up his bike first thing in the morning, it would turn over no problem. It was topped up with a short-term charge. However, because the battery was old and unable to hold that charge, it would quickly die after the first crank and resting the rest of the day.
Just because your battery is able to release a short-term charge after a night of charging doesn't mean it is capable of storing that charge long-term.
In literature, you're what's known as an "unreliable narrator". The reader needs to make inferences as to what's really happening between the lines on the page.
If I were to guess, you did not perform the jump-start from your car battery correctly.
I am also going to bet your motorcycle battery is no longer capable of holding a charge.
Anyway, my suggestion is to take your motorcycle to someone who is more mechanically competent than you. No shame in that. Nobody is born knowing how to fix a motorcycle.
