ac delco 80 amp hour agm in my 2017 silverado

Okay I searched high and low for info on my battery in my new truck. It is a AC Delco 94r agm 80 amp hour. It states this right on the battery top. Now the question is, is this a deep cycle? It has a 80 amp hour rating. The trailer wiring is hot all the time from the truck so when I plug in my TC it is connected to the vehicle battery all the time. I am switching over to a 12 volt fridge so I am going to see how this works. I am hoping my 80 amp hour battery is somewhat of a deep cycle also. With the 200 amp solar I a hoping this will pan out. I also have a 105 amp hour agm battery in the truck camper.


I could not get a answer on the battery from anyone. Including Johnson controls all though they make the battery they said you have to contact AC Delco. Well tried that got no where. Then I called the dealer and asked what kind of battery it was they said it was not a AGM. Well it definitely is a AGM.

So this is the battery. ac delco 94r agm 80 amp hour

We only camp occasionally so I am not overly concerned with running the battery to low. I always have a jump starter and genny with in case that happens. If we camped a lot I would not go this route but I think this should work.

Any opinions on this battery?
Just curious if this would do better being deep cycled now and then than a regular flooded starting battery.


Thanks

  • Any battery sold as a "starting" battery or even a "dual purpose" battery is NOT a deep discharge battery.

    Also, if it has a CCA (cold cranking amps) or MCA (marine cranking amps) rating, it is NOT a deep discharge battery
  • Jim Mkirsh I also have 105 amp hour agm in the truck camper. I edited my original post to state that. I don't know if you thought I meant run it on the truck battery only.
  • Most likely it is NOT a "deep cycle" as it is the starting battery for the vehicle. Deep cycle batteries are designed for low current draws while starting batteries are designed to provide high amps in short bursts.
  • If you are getting an electric refrigerator, I strongly recommend a bigger battery bank. A small Novakool or equivalent refrigerator will pull over 3 amps. In hot weather, it will run close to continuously. You can easily go through 60-70 AHs in 24 hours. You also need to think about the inconvenience of camping in the shade or having a couple of cloudy days. You should have about 200 AH of battery to match the 200 watts of solar.
