Fried the stock battery, I think the Stereo, heater and winch were to much, got a AGM 900 CCA at 32. No more dim lights when powering the winch.

Well in that case yes you needed a higher amperage battery.One of the cells died, the fuses are for over amp drawl, the battery capacity coulded handle all the amps being pulled, the alternator charges the battery, it doesn’t run the accessaries. They put a larger battery in the ones with the winch and radios, I didn’t get that one. So I had the smaller battery
Jgeib,thanks for sharing this info. Glad your battery issue is solved.Here is what I got, fit perfect, it’s a shorter battery. It came with a tray at the bottom to raise it up. To short without it,

Everyone on this site know's I'm not interested in spending more than I have too and there's no way I would have replaced the battery without doing a few more tests......Personally I'm a little confused by your explanation. I'm in agreement with many of the respondents about your fuses and the condition of the cells. I'm curious did you pop the covers off the cells and check them with a guage? You can also do a load test by disconnecting the computer and cranking the starter. A good battery should be able to crank for at least 30 seconds.
Don't the stock batteries come with a year or two warranty? It's a standard automotive battery. Unless you wanted to upgrade to AGM. Note, Optima have had issues some time back.. I don't know about it now. Lessons learned, get an AGM with a good warranty.
A battery is considered dead at 10.5 volts, that is why they may not take a charge again.
I doubled up on my old Rhino using a battery isolator. For people not familiar with a battery isolator (common in motorhomes) it will charge your main battery first, then charge the secondary and if you run your accessories off the secondary and kill it, your vehicle will always crank. I did this in the Rhino cause the battery is so small. My plow puts a good draw on the system with the heater and lights on on the Roxor.
Yep, your numbers are right. Every chart has numbers close to those, but when I said 10.5 is dead, I meant it is completely dead. This is hard to read with the logo over it, but the first one is “state of charge”.This isn't what I was taught. 12.8 volt means fully charged. 12.4 means half charged, and under 12 volts means it's dead. From there you need to charged it and see what the voltage is after it's charged up. Hopefully it'll stay at 12.8 volts. Then you should load test it by disconnecting the computer and cranking the engine. The battery should be able to run the starter for at least 30 seconds. That's how I've always done it.
