12v battery question

[djs100]

Came across some batteries that seem fairly new, but don't think they are deep cycle. I think they were used as computer backup or from a solar system. Does anyone know if I could hook them up parallel and use them to run 12v items on my trailer (fridge,lights)? They are 75Ah. Don't know if two of them would last longer than the deep cycle I'm now using. Any thoughts? Thanks

They should work OK for what you want to do. Hard to say if they are better than your deep cycle, but I don't think you'll have any issues using them for camp power.
