Hey all, so still relatively new to the grizzly. I got it in late June it’s a 2016. I drove it for a week or so then I couldn’t make it back to the cabin for 25 days. When I got up there this last weekend the dash would come on but not enough juice to turn her over. So I put a charger on it, one that works for AGM batteries and waited a while. I was then able to fire her up, I went for a nice long ride, say about an hour or so, and came home. Parked it and ate some food. Then went back outside to move it and she started but struggled. After another hour or so went back out and it wouldn’t start again. Even when the battery charger said it was fully charged I could only get a few starts and it would die. However once it was running she ran great. So I have a few questions:

Is 25 days too much for them to sit? (I do have three other quads that sit in the same shed and have never had this issue, even when going months in between starts.

This is the first ATV that I have a winch on, would that be causing the battery to drain even when not in use enough to cause this?

Any other ideas? I have it at the dealer right now (break in service and looking into this issue) but wanted to get some community wisdom before talking with them so I have a little more knowledge.
