Winch / Battery Question

I am looking to install a Warn VR8000 winch on my 2013 Tacoma and I was checking the my battery CCA rating compared to what Warn says is required. I want to see if anyone here has had any experience with this winch . I have a stock OEM battery which is rated to 710 CCA, Warn mentions having a minimum of 650 CCA for the VR8000, which sounds like the battery has the capacity, however given how close it is I am curious if anyone has had any problems with a similar set up.

Additionally When looking at the performance specs at a full 8000lbs pull it will draw 457 amps, given that the alternator installed in the tacoma (again stock OEM) is only rated to 130 amps, am I going to run into trouble draining the battery quickly? The battery has a reserve capacity of 165 minutes.

Any information / experience would be greatly appreciated!

 

Your pull will only be at half to 3/4 load if your pulling yourself out of something for the most part, and you're not going to be pulling at that load for more than a couple minutes anyway. I'd be more concerned about overheating the winch for prolonged pulls than draining your battery. Just make sure you have really good connections at the terminals and at least 2/0 cable to the winch. I have a Warn M8000 and I'm going to replace mine with 1/0 welding cable and replacing my terminals with these:

Good to know! Thanks for your help.

 

Deep discharges on car batteries will prematurely shorten their life. When you replace it, you might what to consider a deep cycle with enough CCA to start your engine or a dual battery setup. If you have trouble keeping your battery fully charged, then a high output alternator replacement or a dual alternator setup could be installed. Winching at high idle will take some of the load of your battery and Clint suggested, short bursts to keep from overheating the winch motor and large diameter power cable [to reduce voltage loss]. Same rules for starter motors.
