Good comments thus far. Would appreciate more like MEXICOWANDERED where a specific battery is recommended. The whole point of this discussion is that I don't want to be at a remote location, trying to load up a vehicle, and have my battery **** out. (Squeezing every last minute of life out of a battery is not a goal). If a "jump start" battery is a viable option, that would be good, but I need more confidence that that would work.
The reality is most battery name brands are just brand names slapped on, only a couple of FLA battery manufacturers exist so asking for a name brand recommendation of which brand is best comes down to opinions based of some sort of experiences.
Example, from my teen life up to the point that Sears fell apart and disappeared from the world I used nothing but DieHards. Got reasonable service life from them and they had the longest warranties you could get and Sears had stores everywhere and the batteries were more expensive (more expensive means better, right? No, just meant I was paying upfront for that premium warranty.
I could say that I still recommend DieHards but Sears only exists on paper and the DieHards you can buy now days is most likely nothing more than a cheap knockoff store brand rebranded since the the NAME DieHard was sold out of the Sears branding just like Craftsman Tools.
I started buying Sam's club batteries when Sears left town and have not looked back. For the same size battery at Sam's I saved easily $50 and yet Sam's batteries for me have been just as good or even a bit better than DieHards.
What you are looking for is a larger battery in CCA and physical size, not a name brand. Mex mentioned Group 27 and Group 65, I would concur with that. Group 27 has more CCA and physically larger than Group 24. A group 65 has more CCA and is larger than a Group 27.
Group 65 is typically a pickup truck battery which is what my trucks takes and is what I use for a winch battery.
Personally, for emergency winching instead of worrying about your winch battery going dead you can simply make your own extension cables to connect your winch battery to your vehicle battery which 100% eliminates the need or worry to carry a spare or backup winch battery. Those cables do not need to be recharged or maintained so they are 100% ready to use anytime you find yourself in a bind.
A brother of mine even added permanent winch power that runs from the truck battery back to a heavy duty connector on his bumper.. All he has to do is connect the cable from the winch to the truck and is done.
If your vehicle takes a group 27, buy a spare group 27 for the winch.
The only time I ran out winch battery was when my old winch motor had a catastrophic electrical failure, overheated and died in the middle of pulling a car up my trailer ramp. I blamed the battery, replaced it with a new fully charged battery and the winch didn't respond..
Sam's club or Costco, the best prices in town on batteries and they will live well past the 3yr warranty unless you forget to charge them.
