Have had the batt in my '18 run down a couple of times. Once I had left a GPS plugged in for several days, and after that it had set for a week or two. It takes a charge and may be ok but I intend to take it to AZ and have it tested.

I have no need for a larger battery and don't want to bother trying to fit one. Looking online I found one Yuasa a bit stronger that seems to be the right size. It is 32amp/500cca and OEM is 30/400. No sure any of this matters a great deal, but thought I'd toss it out for general interest.

I wanted to research the specs for the battery you listed(just out of general curiosity since I have a 2015 Slingshot), but quickly remembered how much I hate websites that don't want to allow me to search for a part w/o telling them what vehicle I want it for. Both AutoZone and Oreilly wouldn't let me search w/o providing vehicle info. I'm old enough to take responsibility for determining I know what I'm looking for!
I'd assume that battery will work and found prices for what appeared to be equivalent batteries ranging from under $100 to $200+.

BKL: didn't the '15 have a car battery and in '16 and beyond Polaris put in the smaller motorcycle one to save weight?
The one I list above has virtually the exact same dimensions as the OEM which I believe is this one:

Yes. In the latter half of 2016, Polaris switched from a heavier car-type battery to one sized for motorcycles.

I just looked at that battery. It says 30/400 not 32/500.

The battery in the OP's html says 32/500 on it, although the web site specs. say 3.2 ah.

 

[Howarduliketoo]

I'm not here to argue. I just read what they have on that site you posted a link to.

 

[openair]

I did not post a link to ANYTHING. Here is the ORIGINAL link posted by someone else:
https://www.yuasabatteries.com/battery/gyz32hl/

This is a picture of the battery shown in that link.
On it is printed the words "12V", "500CCA" and "32Ah/10HR"
It also lists the charging rate as "3.2 amps x(for) 5 to 10 hours.

 

[Howarduliketoo]

I stand corrected. It was some body else that posted the link to the other battery. My apologizes.

Seems like if you filter by Slingshot on their site it actually pulls this on up and the stock OEM version. Seems like a direct replacement and newer technology. Win win in my opinion.
