My house batteries are not holding a charge. They also don't seem to be taking a full charge. I have 4 Trojan house batteries in my 04 Revolution. I can't remember exactly how old they are, but I'm thinking they're at least 7 years old, What do you think? Time to replace or ??

7 years is what I got out of my Costco golf cart batteries in my former 2001 Monaco Diplomat. I replaced with 4 Kirkland gc batteries. At 7 years I had no complaints. Good luck, Don

Absolutely time to replace. Hands-down. I don’t even give it a second thought. My motorhome is 17 years old and I have replaced the house batteries four times. In fact all of the batteries.If you want good reliable service do it.

recharge, then do an equalization charge, follow that with a total discharge and a
full recharge.

Lead acid batteries typically last 7-10 years with proper care. I've heare of them lasting longer on RARE occasions.
Based on your "At least 7 years" time to replace.
Home was where I park it. but alas the.
2005 Damon Intruder 377 Alas declared a total loss
after a semi "nicked" it. Still have the radios

I thought for sure this season I would have to replace my 2 6v Sam's Club batteries because they are 14 years old and they were self discharging faster than normal, but I dry camped with no generator usage for 5 days last week and batteries were at 60% SOC. Usually they are at 50% after 7 days so I think they are good for another year. My previous set were Trojans and I replaced them at 4 years not knowing how to maintain them.

To answer your question, while AGE certainly does contribute to batteries loosing capacity, if they fail at one year or 10 years old, replace them!
If the batteries fail this test, irrespective of age, replace them:
Separate the batteries for testing.
Fully charge them.
Load test them (any place that sells batteries will do this for free).
If wet cell batteries you can also buy an inexpensive BATTERY HYDROMETER (under $10 at any auto parts house) to test them.

If you depend on the batteries, replace them. If you only use campgrounds with electrical hook-ups, you may get some more time out of them but 7 years was a pretty good life for wet cells.
If it were my coach, they would be replaced because bad batteries are a pain and in the scheme of things, the cost is small compared to what we spend on our RVing .
