What voltage under load is 50% T-105's

I have two trojan T105's for my toyhauler.

For the most part, my norcold refrigerator is the only load , other than a occasional light in the bathroom and the water pump. We use flash lights allot after dark and usually go to sleep then.

With the norcold as the load, what voltage measured at the battery terminals would indicate they are at 50% capacity and need charged?

I charge daily but wonder if I'm using more than 50% per day.

Thanks

It sounds a lot like you have a converter in your trailer that doesn’t have a smart three stage charger built in. You battery is never fully charging because the converter voltage is at the minimum. You might be able to add the charge wizard to you converter.
