Radio Flyer1647545514 Posted October 21, 2016 Report Share Posted October 21, 2016 I didn't know how much response I'd get in my climbing thread so I'm making a new post. I want to run an ARB fridge but I don't understand what my setup is capable of. I put an AGM battery in my truck that has 840 or 880 CCA. the fridge I'm looking to get seems to pull .82 amps per hour from my research. I will add a solar panel to help supplement recharging my battery (I don't know how much that will help). I'm open to the option of buying another battery for the fridge only of that's the best route for me to take. It sounds like I'll want to run the wiring for the fridge directly to the battery from the reading I've done. I'm driving about 30 min each day right now but there is a chance I could go up to 3 days without moving my vehicle. Quote Link to comment Share on other sites More sharing options...
SPL_Josh Posted October 21, 2016 Report Share Posted October 21, 2016 What's the reserve capacity of the battery and what aH rate? That's more important than ca/cca Quote Link to comment Share on other sites More sharing options...
mmrmnhrm Posted October 21, 2016 Report Share Posted October 21, 2016 Yup... CA/CCA really doesn't matter in this situation, that's a measure of how quickly the battery can give you power. Here you're looking for a slow and potentially deep discharge, where amp-hours or watt-minutes determines how much power you can pull out of the thing. If you expect to be using this a lot, go for a deep-discharge marine battery, like what you'd hook up to an electric trolling motor, not a regular starter battery.

Can't find ah ratings on it. It says 160 rc on it. I'm assuming that's reserve capacity. Quote Link to comment Share on other sites More sharing options...
iwashmycar Posted October 21, 2016 Report Share Posted October 21, 2016 Very well may want to just look into dual batteries....that way if you crap one out you can switch to the other for starting the vehicle and recharging the down one. If you are just using ONE battery it needs to be a deep cycle so you dont damage it by always running it down. Supposedly the fridge will shut down at a certain point if the battery voltage is too low anyway Quote Link to comment Share on other sites More sharing options...
SPL_Josh Posted October 21, 2016 Report Share Posted October 21, 2016 You only have the starting battery? Might want to add more to be safe. Quote Link to comment Share on other sites More sharing options...
Radio Flyer1647545514 Posted October 22, 2016 Author Report Share Posted October 22, 2016 I only have the one listed above. Would I be looking to get another am deep cycle for the fridge? Quote Link to comment Share on other sites More sharing options...
Radio Flyer1647545514 Posted October 31, 2016 Author Report Share Posted October 31, 2016 If I got two batteries to power the fridge and hooked them up parallel would I want am deep cycle or regular lead acid deep cycles? I figure I need 168 ah per week before recharge. Quote Link to comment Share on other sites More sharing options...
iwashmycar Posted October 31, 2016 Report Share Posted October 31, 2016 Youll want deep cycle if you will be regularly running them down. Quote Link to comment Share on other sites More sharing options...
Radio Flyer1647545514 Posted October 31, 2016 Author Report Share Posted October 31, 2016 Youll want deep cycle if you will be regularly running them down. Is there a reason to get agm deep cycle over lead acid deep cycle? Quote Link to comment Share on other sites More sharing options...
iwashmycar Posted October 31, 2016 Report Share Posted October 31, 2016 Either is fine but the AGMs seem to last longer charge wise when not in use Quote Link to comment Share on other sites More sharing options...
SPL_Josh Posted October 31, 2016 Report Share Posted October 31, 2016 Is there a reason to get agm deep cycle over lead acid deep cycle? Agm can be in the same cabin space as you because it's sealed. Regular deep cycles arent sealed. Quote Link to comment Share on other sites More sharing options...
