Battery question

[johnnycat8]

Its all a function of the current draw of the accessories you use.

The limiting factor is not the battery, but the charging system, that being the stator.

The stator on an 800 is sized to handle just the stock RZR. There is some to spare, but not a lot.

Using a winch, you'll see the system voltage pull down pretty good. So long as you don't use the winch for more than a few minutes, the system will recover quickly.

LED light bars use very little current compared to the old style halogen lights, so that's not much of an issue.

Stereo system use a lot of current, so if you're using it all the time...you're liable to pull the system down far enough to kill the engine as there are components that have low voltage shut offs.

Get a good voltmeter and install it where it can be seen, the dash, and use that as your guide. If your voltage gets in the low 12 volts and stays there, shut something off until you're back in the 13 volt range.

A second battery with a smart isolator will allow the "starting battery" to stay fully charged and only charge the "accessory battery" when the system voltage is above 13.2 volts.

Thus if you are using the accessories that put a heavy draw on the accessory battery, its liable to "die" during a long riding day. As the RZR electrical system may be working hard to keep the "starting battery" at 13.2+ volts and thus doesn't provide current to charge the "accessory" battery often enough to keep it charged.

Use a battery charger to charge it overnight...and you're ready to go.

on thing most people forget is the power used for just the stock stuff.....fuel pump, radiator fan,ecm,all the sensors and coil ,lights, i havent figured it out on the newer stuff bit on a bone stock 800 it used just over 65% of the stators capasity.... so not much is left
