Both of the ATV batteries were about 5 years old. I bought a couple different 2017 midels in 2018. My other ATV is 22 years old. Its a snap to do most anything with. Its car berated and very little electronics on it.

The truck is easier. Its not hard to get to either one. But they need to be replaced at the same time. It gets expensive and I think next time I'm going to go for a bit pricier battery to deal with the cold and heat here.
