What is recommended battery?

I recently bought a 2010 Interstate (Class B) and need to replace the battery with two lifeline AGM's. Does anyone have the correct Lifeline Model number for ordering the batteries (12V)?

Thanks

Welcome to the AirForums.

Is it in the Airstream manual?

The supplied batteries on my 2014 are Lifeline GPL-24T's. These are 12v batteries. You might consider upgrading to 6V batteries witch will increase your capacity. Two Lifeline GPL 4CT's, connected in series will increase your rated capacity from 160A with the 12v 24T's to 220A. The 4 CT's will fit the OEM battery box and you shouldn't have to buy any additional cable. I was able to configure mine in series with the existing cable and had a piece left over. Cost should be about the same.

Good Luck

Oops, I just reread your post and noticed that you mentioned replacing the "battery" not "batteries". Did your 2010 Interstate come with just one house battery?

I think I would like to do what you have done and replace with 2 6V wired in series. Question, does the existing Magnum inverter/charger work for this system. Did you change any settings? Thanks

I bought the unit from a dealer that installed one battery. Not sure what he put in yet but it doesn't seem to hold a charge at all. Not surprising based on other things I found. Trying to figure out what to get before I take it apart to get down to it.

Thanks for the help from a new guy.

2d reply. I haven't changed any settings but will have to check them closely when I replace batteries. The inverter charger does charge the battery but it doesn't seem to hold and the refridge will only operate a very short time on the battery.

Everything will work as before because you still have a 12v system. (you are just using two 6v batteries connected in series to get to 12v). The only other changes I made to my basic system was to replace the installed Magnum Remote Control (ME-MR) with a Magnum ME-RC Remote Control and installed a battery temp sensor. (ME-BTS) These changes aren't mandatory but recommended for better battery management. The remote control hooks up with the existing telephone cable. If you don't want to cut the hole bigger for the monitor, they also offer a surface mounting bezel that will alloy you to avoid any cutting. The ME-RC will allow you better control of the Magnum Inverter/Charger including setting it for the actual battery capacity. Magnum recommends the installation of the temp sensor but for some reason, Airstream has been leaving them out. The temp sensor uses a phone type cord which simply connects to a battery Neg terminal and plugs in to a port on the inverter/charger. Do a google search for these parts and you can find plenty of discount sources.

Is the original battery box still there? Hopefully it is and has room for two batteries. You can go to Lifeline's website: lifelinebatteries.com and check out the dimensions of their various batteries.

My 2012 has a house battery box that has two batteries stacked one atop the other with a wooden false floor in between.

It's entirely possible that your Interstate came with two house batteries, but the dealer only replaced the top oneó not realizing there's another beneath itó leaving a stony dead one in the lower position.

That situation, with one new battery and one old dead battery, would exhibit the same symptoms you described.

This is what the dealer installed for me. I hope this helps narrow down your search.

Given that it's low pressure, how does one hook up a tabletop propane grill that uses the small bottles. I have a quick connect hose and an adapter that hooks to the regulator, but that is too restrictive--no flame. If I remove the regulator and insert the hose directly into the burner, the flame burns, but it is a really high flame (not blue) with no control? Thoughts? Anyone have any luck making this work?

On my grill, (Camco), the manufacturer offered a control valve that replaces the regulator on the grill. That solved the problem for me.
