My Polaris UTV had a Polaris labeled OEM battery that lasted 11 years amazingly. It finally crapped out a few weeks ago. Walmart has several levels of Everstart AGM's. I got the one with 385 CCA. The other's are 310 and lower. If it could start in gear, it would lay rubber. Now we'll see how long it lasts. I've had very good luck with Everstarts in other vehicles.
I use it for plowing snow so it gets some use in cold weather. We'll have some extended periods with no snow so I run it a few miles every few weeks to get the engine hot and charge up the battery. It also throws some oil around in the gears so they don't sit dry for months on end.
