Welcome to the forum

 

You'll get lots of opinions, but probably a universal one is that you don't need OEM Polaris. However, there is a lot of junk out there so if you aren't sure then you could just get OEM.

I get Interstate Batteries for all of my boats, ATV, truck, and snowmobiles. However, the ones at most stores are junk in my opinion. I go to a distribution store near me that has a little retail shop in the front. I have gotten great durability out of the ones that I have bought there.

 

Odyssey makes excellent batteries. They are absorbed glass mat so there are no acid leaks over time.

 

I buy mine online form Batterymartcom. They have batteries made by DEKA.

 

I've had good luck with AGM batteries, not sure who makes them but I've bought from Fleet Farm and Cabela's in the past.

 

does anybody use a lawnmower battery for their sportsman? mine is a 2024 & the SLA appears very similar to the lawnmower battery.

 

A friend of mine worked at Johnson Controls battery division, he said they take apart all brands to analyze them, and that Exide was one of the worst made.



Johnson Controls® manufactures brands such as Duralast®, Diehard®, Kirkland®, Motorcraft®, and Interstate®.

Just remember that almost more important than the battery, is making sure that you keep the battery on a quality maintainer if you aren't using the ATV on a regular basis.

 

I used a 4 battery Battery Tender. I keep it on a timer so it only charges at night when the ambient temperature is cooler. I set the timer for 4 hours midnight to 4 am. I found that keeping the tender on 24/7 eventually kills the battery, especially OEM and lead acid batteries. I like the AGM batteries.

 

I'll occasionally plug my ATV battery to my Battery Tender, as well as my zero turn mower. Works like a champ. Got tired of being stranded ice fishing and no start!

 

I keep my 3 boat batteries and Zero Turn mower on tenders all Winter long, have done many batteries that way for 50+ years, never ruined any.

 

The small tenders I used in the past, plugged in 24/7 boil out and ruin the batteries way too early. They would overcharge. When I started putting them on a timer and shorten the charge time no problem. I also have a lot of time, 60+ years learning how to treat batteries and keep them lasting longer. For the last maybe 25 years I have a large metal toy barn, with 2 boats, a camper, 5th wheel, zero turn mower, Polaris 800, Polaris General and a dump trailer. It gets hot during the day even in the winter here in Northern California. The heat in the building and charging during the daytime is a battery killer. It really depends on the ambient air temperature the battery is exposed to while charging. This method over the years has doubled the life of most of my batteries.

 

Must be some lousy tenders, even our firetrucks are on tenders 24/7, not once did we ruin a battery.
My 2 ATV's and one SXS have tenders on them, the battery in my 2015 RXR (9 years now on the same oem battery) and my 2016 XP all have the original batteries, my 2015 XP 1000 had 1 battery finally get weak BUT I snowplow a lot with that ATV, my son in law took the old one and is still using it today.

 

I was going to say something about that yesterday but didn't. Yes, the tenders or maintainers these days are calibrated to not burn out batteries. Get a quality unit and don't worry about it again.

 

That's true, as the batteries charge the chargers reduce the amps and as the battery requires more the amps increase etc. etc.

 

They really aren't continuous charging, they are simply maintaining the charge.
