Cost to replace house batteries on Interstate GT

I would appreciate any guidance as to cost to expect to replace the current and original batteries in a 2018 Interstate GT with new batteries. A ballpark figure will be sufficient for the batteries and associated labor.

Thank you in advance.

If you go to Interstate Batteries, they will replace them with no labor charge.

They could also give you cost estimate for different types of batteries.

We have always used Interstate, and been very happy with them.

They have gone up 50.00 since I got mine... 299.99 each with free shipping.

This is for the house batteries: Lifeline GPL-24T

These guys have the original batteries on sale for $259, but I think you have to pay shipping.

Also, to answer OP's original question, I just had mine replaced. I took it to Windish RV in Fountain, Colorado, which is an authorized Airstream service center. They charged me $250 to replace the batteries. I thought this was excessive given it took them less than an hour to replace them. I will likely not go back there in the future.

Free shipping as well from that site you shared. So they are better priced than the link I provided.

As to the cost of installing them... these are heavy and not easy to managed under the AI... In my case I had to raise the back as much as I could with the Air Suspension...

So just be careful if you are going to do it and use a motorcycle jack or something with good enough surface that will make it easier to raise into the tray...

I had the invertor and batteries replaced for total labor of $390. Batteries were $ 298 each. Done this past December. I believe they are the same in 18 and 15 but check on that.

You might consider replacing them with lifeline 6v AGM batteries. They cost slightly more than the 12v Lifelines but you get 37.5% more capacity. You will have to make sure they will fit in the battery racks and you will need to wire them in series instead of parallel. You can obtain the dimensions on the Lifeline website and compare them to what you have now. Swapping batteries is a pretty simple DIY project even changing the wiring configuration. You probably have enough cable and should have a piece left over. I have seen them recently for $330 shipped. The ones you would need are Lifeline GPL-4CT.
