I have a 2004 Polaris Sportsman 700 twin. I have been buying YUSA batteries (about one per year) but they continue to go bad. I have changed the starter and regulator in hopes that may be draining the battery but no luck. I have winch and I leave the cable hooked up to the battery but the winch is not plugged in. Is anyone having similar issues or know how to rectify this issue? I would appreciate any advice since this is getting expensive.
