JOOC, what is the CCA rating? I don't recall seeing it in the comments.
There aren't many of us who run winches, but thems of us that do want quite a few (650 CCA is not uncommon, and some winch manufacturers recommend deep cycle batteries like the Yellowtop Optima).
- aggie 11y agoTheir site says '550+'. From the sound of it, this battery would not be suited to running a winch for more than a quick pull.
- PeterWhittaker 11y agoThat was my impression, as well.
- conjecTech 11y agoI'd be very interested to see what the current use on a winch is! Do you happen to be located around the bay area?
- PeterWhittaker 11y agoNo, Ottawa. A quick search shows that some lighter duty winches will draw 60-90A, while heavier duty winches can easily draw ~250A to ~350A. The winch I'll be installing next month as a 10,000lb pull rating. That requires a lot of power.... (Why 5T? Because my Jeep weighs a hair over 2.25T, and if it's stuck in the mud, I'll need to overcome the mud....) A winch is typically connected directly to the battery and is controlled via a relay: The control cable uses very low current to activate/deactivate a solenoid that switches the winch on/off. (It's an interesting and ironic bit of jargon: When winch owners refer to a winch's solenoids, they are referring to the control relays... ...but any winch contains at least three solenoids, one low-draw solenoid in the relay, and two high-draw solenoids in the winch itself, that is, the electromagnets that are the heart of the motor....)
