Winch Battery

[DougE]

I have a DieHard battery, not sure what vehicle it was sourced from, that I have been keeping on a trickle charger for years. Date I wrote on the battery was 10/14. I use this as a standby battery, but primarily use it on rare occasions to power an 8000# winch on my car hauler trailer. I suspect I should really get a deep cycle battery for a replacement before this decides to die on me at an inappropriate time. Suggest a good, economical replacement!

I got a GOOLOO GP4000 jump starter lately. It never occurred to me that I could use it in an emergency to power my winch. It's rated at 500a for 5 seconds - not sure what the continuous power output could be.

Maintenance with a SiO2 batter is about zero too. No need for trickle charging.

If the battery shows no sign of failure, I'd simply keep using it...maybe get a set of jumper cables so you could connect to the truck battery in a pinch.

If you still feel the need for a spare, I would get a cheap starter battery or jump-starter pack. Assuming the winch draws 200amps for a maximum of 5 min, that's all of 17amp-hr. There's no need to pay a premium for a deep cycle or other specialty battery chemistry.

You can have good, or inexpensive, but usually not both. Winches are fairly high draw. My own personal choice would be an SiO2.

But if the existing battery passes a load test, I'd continue to use it as in the past.

I have a winch on my cargo trailer. I use a group 24 deep cycle battery.
