If you have a wireless winch controller it will drain it rather quickly. I have an isolator switch on mine to prevent this.
I echo this post. The remote transmitter draws enough to flatten a battery in 3-4 weeks or sooner if very cold out. A simple toggle switch in the remote transmitter positive wire completely solved it.

You said you have added a winch. If has a wireless remote and is not wired correctly it will drain the battery in about a weeks time. remote needs to be wired to power source only when motor running.

If you get the power from a keyed power supply, IE the power outlet, You wont have a draw issue.

Well sort of...if the motor dies I might still need to use the winch. I prefer wiring it live to the battery with a switch to cut the power to the remote transmitter.

If you wire the winch control switch to the main switch, power off lead, the winch will work with the switch in the on position and engine not running. I wired mine to the winch mfg. instructions. I may have got in a water hole a little too deep once upon a time and had to winch out without the engine running. Not saying I did, it just may be I imagined it in my my old age. Hehehe😂😂😂😂😂. Electrical problems can and will drive one to drink if one is inclined to do so. Just saying. Good luck.

Got my machine back from dealer a couple days ago after taking it in for this battery issue and it's annual service.

Problem was lose cables. When I most recently replaced battery back in October, I went to Lowe's and got some longer bolts to use to connect the cables to battery posts. Why? As anyone who has replaced the battery in the P5 knows, it is a pain in the ass to get the bolt through the cable eyelets and then get it to thread up into the battery terminal posts. So, I thought longer bolts would help make the process easier, which they did. I was able to find longer bolts which matched the threads and get em cinched em up tight, but they apparently did not stay tight, and according to the dealer's tech, that loose connection allowed the battery to drain. He recommended always using the bolts that come with the battery.

Fortunately, battery was still under warranty. Once they installed new battery, they checked electrical system for any parasitic draws and found none. Guess I gotta chalk this one up to bad luck. I now have a Honda OEM battery in the machine instead of a Huasa, because Huasa's were on backorder. Honestly, I'm glad as I had better luck with the original Honda OEM than I have with any of the Huasa's that have been in the machine. So, hopefully this problem is behind me.

I will add - service tech told me that battery quality, just like everything else, has been going down for several years, and it is therefore imperative to keep the batteries on a tender or some kind of trickle charger when the machines aren't being ridden.

I appreciate all the comments with suggestions trying to help. Thanks.

I think you mean Yuasa, that is an oem and they are on backorder.
