When I wired by handgrip and throttle warmers last weekend, I inadvertently wired them to a battery-hot wire, not an ignition-hot wire. Wouldn"t you know the first time I used them I forgot to turn off the switch. It was on for 3-4 days and the battery was totally dead.

I've had it on a charger for over 6 hours now, and it won't get above 6.8 volts. It'll have to be replaced. My question is this... does anyone know what type of battery is in an 08 Sportsman 800 EFI HO as far as the type? If I have to replace it, I might as well try to find one with more cold cranking amps than the stock Polaris one...

I went to Walmart and used their computer by the batteries for my battery.

 

I believe I found the best replacement battery for the 800EFI. I decided to go with a Yuasa YIX30L. It has the exact same dimensions, has 385CCA compared to the Polaris factory battery's 365CCA. And also as 30A/Hrs. This is an upgrade from the factory battery and should do better winching for an extended pull.

I only winch if the ATV is running and the tires are helping out,so I just buy the cheapest walmart battery that fits. $32 last time.

 

But I plan to use my 800EFI to work (winching logs) and help clear a wooded mountain lot. I'll be using it at night to light up my work area... which means it'll be running at idle for extended periods with both the low and high beams on. I don't want to risk running down a cheap Walmart battery because the alternator is not putting out as much power as I'm consuming and having the Polaris die on me.

As it doesn't have a pull-start option, I'd be forced to pull the battery out of my JK Jeep, carry it up the mountain side to the ATV to jump start it.

Nope, not for me, if I have to replace it, I want the best battery I can squeeze in the hole that will last the longest before it gives up the ghost.

I put a 10amp charge on it last night for about 20 minutes to try to desulfate it somewhat, then dropped the charge to a 2amp trickle charge. When I get home, I'll pull it off the charger and let it sit for 2-3 hours, then will check the voltage and see if it'll start the Polaris. If not, I'll order the new Yuasa.

Oh yea, and I'll also rewire the darn hand warmers via an ignition-hot wire so they shut off when I kill the Polaris.

I bought my battery at Wal-Mart. It was 1/2 the price of a new one at Polaris. My original only lasted 1 year and I had this battery from Wal-Mart 3 yrs now. I have run it dead 3 times and just used my pull start and rode the wheeler around for awhile and it charged itself back up. I'm happy with it!

Say where are you guys getting you hand warmers and throttle warmer?

 

Got mine from a dealership in Chattanooga, TN.

if the battery was charged up right the first time then having it run down like that shouldnt have killed the life of it for sure. if your charging it at 1 or 2 amps it would take 8 to 10 hrs to charge it anyways. just a thought. oh and the 800's only put out 500 watts.

 

Roger on the 500watts.

Well, it was on a charger for 10 amps for 20 minutes last night, then was on 2 amps for 20 hours. When I got home today, it was reading 11.68 volts. I expected at least 12 volts. I put it in the polaris, and it has enough charge to fire up the fuel pump, but only clicks at the starter solonoid when I try to start it.

I agree, I've NEVER seen a battery die so fast and be totally resistant to taking a charge, especially a battery that is only one month old and one that has suffered only one discharge.

Truely pathetic. I sure home the new Yuasa performs better than this...

Anyone else with similar experiences? Did I just get a bad battery? Does everyone agree that it should revive better than 11.6V after a full 24hr charge?

If it's only a month old, take it back for warranty. They should be good for it.
