Simple first time it is sluggish starting charge it up. If it does it again change it. These newer bikes need to be on a tender when part as much as you can to extend battery life.
I'm pretty sure that Craftsman is made by one of the major battery makers, like East Penn. Yuasa and Koyo are big Asian makers and Yuasa is popular on this forum.
I have a Yuasa in my King for almost 6 years now and that thing won't die. I had the OEM for 5 before that and I'm in NC. I also have a lithium in my Sporty going on 5 as well.
True on the Craftsman, Harley, and US made Big Crank Batteries, they are all made by East Penn but some specifications are a bit different, hence the spacers on the Big Crank Batteries for HD.
My son is an mechanical engineer, works for Yuasa; the Yuasa Motorcycle, ATV, UTV, Snowmobile, and Jet Ski batteries are made in Reading, PA.
Probably try a Yuasa the next time I need a motorcycle battery.
As mentioned a simple load test will give a view as to the health of your battery and charging system if done while in the scooter ... Here's a simple explanation of how to use and what it can do ... It's a handy tool to have around ... I have one similar ... There are more sophisticated units available but all do basically the same
I have been getting 4-5 years on whatever brand I buy. I typically replace at 4 yrs because I don't want to get stranded. I do carry a small jump start battery by WeeGo
I get a year out of any battery I've tried, including the Big Crank. They do OK until it gets cold (15°F this morning) and then they leave me stranded every winter. I've started replacing them as they begin to slow to avoid this. This time I tried a USA made brand - We'll see. Someone's going to mention I should have the bike on a tender - I ride it multiple times a day, sitting isn't the issue.
