I've had the YAUSA batteries... they dont hold up.
They advertise "twice the power and triple the life of conventional lead acid batteries."
Now the 2017 one is dead dead. hence to search for a new one.
ALWAYS on a battery tender. After EVERY ride when it goes back into the garage.
Sorry but this sounds like a cheap Chinese "knock-off".....and you probably should not expect more than 2-3 years service from it.It was a SigmasTek YTX24HL-BS
and do not strictly follow the filling, charging and conditioning procedure, it would explain the very short life.

I see lots of batteries with equivalent CCA and other ratings.
Duracell
Chrome/Pirate batteries
Durablast
etc
I'm leaning towards the Duracell Ultra 18L-BS AGM battery from Batteries plus as they offer a 24month warranty.
I suspect the batteries you had were not properly conditioned before you started using them. And, as others have said, always on a tender is not necessary and will be harmful if it doesn't control the charge correctly. I changed the Yuasa battery in my Honda ATV for the first time at 11 years last year. It's only been on a maintainer during part of the time during winters.I've forgot what my earlier history was on batteries on this 2010 RTS.
I do I know I changed it in in 2014, then again in 2017.

IF.....you do not follow the installation instructions for almost ANYTHING, you should not expect it to work right. :yikes:
The other side of that coin is: If you DO follow the instructions, which probably does NOT include any "conditioning", the BS version should be just fine.
Your 'probably' would be wrong and the reason for short life of the -BS version in many installs, and BRP's recommendation not to use them in the Spyders.
Mighty funny that at least one battery maker says flatly that there will be NO DIFFERENCE between one that is user activated and one that is factory filled.
I fully appreciate that you think you are providing good information here.......but I respectfully insist that it is NOT good advice.
Users can make up their own mind.
You are welcome to do as you please with your bike. The 'advice' I am giving is what BRP has relayed to dealers from real world experience. The -BS versions, if not properly activated before installation in a Spyder do not last long. They are NOT the same life span as factory activated batteries for this reason. While it is possible for an owner or shop to do the activation correctly and get life just as long, its not a given and has been the source of problems many times over. This is the reason for the 'advice' from BRP. A tech service bulletin to that effect. I happen to agree with BRP in this case. There is no financial downside to ordering the factory activated version which is KNOWN to be properly activated and ready to install.
Insist all you want, your position does not correlate with real world experience on Spyders.
