Should I replace my batteries?

My two 6V Interstate batteries have been doing very well. They were installed by the dealer before we took delivery of our new X19H in June of 2011.
Never had any issues with them, but wondering now at 8 years of age if I should replace them for reliability assurance, "just in case".
I have never removed the batteries in winter, and the trailer was parked outside, but connected to power.
Most of our camping is dry camping, and we have used the camper for just under 200 nights since we bought it, so there are quite a few battery cycles.
I de-winterized the trailer yesterday, unplugged it from external power, and tested everything. Then let the heater run for an hour or so, the lights for a couple hours, and turned the fridge on. This morning I checked, turned the lights on again, and the batteries are at 12.6V still. So they seem just fine.

So .... would you replace them before the first trip this year if you were me?

    I have two size 27 Kirkland Batteries from Costco , that are nearing 10 years old, no indication of going bad or weak. They have been plugged in 24/7 their entire life except for a few boon docking trips , and then charged up every morning. also the water level maintained. Maybe the secret is never running them down very low, don't know, but they have held up well

    I have no intentions of going out and buying two new batteries until they show signs of weakness. To the OP , if it would make you feel better have them checked. They sound to me like they are still in good shape .
  • If you are still disconnected from power you are essentially dry camping right now. Use the electrical equivalent of what you would in the woods for a few days. If the voltage is where you think it should be, use them for a while longer. I look at it as throwing away money. If you trade out batteries that may have 20 trips left in them, you are using 20 more cycles on you new set that you don't have to. Monitor the old ones until you start seeing poor performance.
  • Since they seem to be in good shape... check the fluid level and keep them.
    Good chance they will serve you well for 2 to 5 more years.

    Worst case you replace them on the road. Not really a big deal.

    It's your call but my experience is batteries always fail at the worst time.
  • One or both will die at the most inopportune moment, replace them.
