Winch battery

[Chilow]

About to purchase a winch and noticed there’s a warning to use it with a battery rated at least 650cca. Is this safe on the battery that came with the 4Runner?

Yeah.

You want to shut down non essential electrical loads and leave the engine running during winching operations though.

The factory Panasonic battery is 530 CCA I believe. I noticed the same warning on my winch, so I played it safe and put in an Odyssey battery rated at 850 CCA (34-PC1500T), and a voltage booster.

The winch would probably run fine on the factory battery a handful of times, but if I'm in a bad stuck situation where I need to use my winch, I want the peace of mind that matters aren't going to get worse by overloading an underrated battery.
