I had the same problem.I put a switch in the line that keeps everything "alive" when the ATV is off. Clock etc. That solved the problem. Hasn't failed to start since I put the switch in. Mine is a 2011 850 Sportsman. I only have 1300 miles on it and is in showroom condition. I've had this problem for years and can find nothing wrong. So either my Polaris has a hidden problem or the batteries today are all junk. I'm on my 4th battery. However this one (since I put the switch in) is holding up just fine and hasn't failed to start or even turn over slowly yet. Problem solved.

Just bought a 2012 yamaha big bear. Been without one for way to long. Lift kits? Obviously high lifter is a go to. Any recommendations?

Back in the saddle. Any of y'all have.any suggestions on stuff to keep an eye on that might be problematic with these.

Between my son and I we have 14 of the Harbor Freight chargers in use. They have worked great.

Sounds like you need a fully enclosed UTV with heat and A/C.

I have seen people do this, even replace the battery with a bigger one, but you have to keep in mind the stator only puts out so much power and if you exceed it, even with a bigger battery, you will be drawing it down as you ride and eventually, your dead in the water. Mike

Wife wanted a radio so we got a radio, now she wants a sort of soft top so she wont get sunburned damn redheads, i want electronic toys but running out of room in front trying to keep rain and snow out of it

If your ATV is a newer one with electronic ignition that will also be drawing a tiny but constant current. Add that to the clock, stereo and any other accessory that must maintain memory settings and the draw on the battery can be significant over a week or more. I have to keep a maintainer on my Sierra because it sits idle for long periods , otherwise the battery goes flat from all those little draws adding up. As Mike mentioned , the alternator in ATVs is minimal so run time to fully charge a large battery could be significant. It doesn't take long storing a lead / acid battery at less than full charge for sulphate to slowly build up and significantly reduce battery capacity. More to consider......If you have a side by side you might find room for a big battery, but not so easy on smaller rigs. Then you gotta consider the battery itself. Do you really want a flooded battery in your ATV ? Most get some pretty significant jostling and way off camber use . Acid leaking out of a flooded batter can wreck havoc, and large SLA batteries can be $$$$$. Unless maintaining memory in accessories and the clock is a must to you, I would suggest instead of trying to shoehorn a bigger battery in ,just install a disconnect switch to shut down all power when the ATV will e parked for a few days or more. Resetting the clock if it's important doesn't take long . A CB or HAM radio gear doesn't draw any more power receiving than any other broadcast radio. They only draw more while key down transmitting, so adding one to your accessories isn't going to affect your battery load to any degree. Just my rambling thoughts on adding a bigger battery .. It can be boiled down to simply saying " It isn't worth the trouble and expense".
