6 volt batteries
Can anyone tell me what is the battery size for the house batteries in a 1998 National Tradewinds model 7370. I currently have four different brand house batteries . I bought this used so I don't know the original specs.

If I understand the question the size of the batteries can be what ever fits in the space! The bigger the total amp hours is what your looking for!

Thanks. I guess I need to know what is the maximum amps I can use without damaging the system?

No minimum amps limit--if money is an issue put in two 6 volts in series or one 12v--less money, less performance.....Depending on you charger/inverter config, you may want/need to change your charging levels to match bat amps hours--if you have that parameter.......

Mixing batteries is very bad in every combination. The weakest battery in the string spends it's entire time drawing from the strongest one(s).
As Dick said, the charger doesn't like it either because it will respond to the demand from the weakest battery and overcharge the stronger ones..
I am a fan of the Trojan T105. I have had several sets over the years in two coaches, with the expected performance. Also like Dick said, I check my battery water monthly. Get the Profill water setup. It isn't cheap but it makes watering a string of batteries a piece of cake! I spend less than 5 minutes doing my 4 Trojans.

I hear a lot of myths about mixed battery banks.. The weakest one draws down the better ones is one of them.
ONLY if it is weak due to a shorted cell.. So long as its full charge resting voltage is proper it will not draw down anything.
What it will do is accept less and less of the load as it ages.. So your total battery bank life will go down and down.
By the same token when charging it will accept less and less percentage fo the total charge.
BUT, another myth is The smaller (older lower capacity) battery will reach FULL and signal the converter to go into float before the larger.
NOTE TRUE of multiple batteries in parallel. (True if in series only).
And when it comes to six volt v/s 12 volt I will answer ALL (But one) of your questions with the next paragraph.
There are no six volt batteries in an RV, There are, however 12 volt, 2 piece, batteries (Broken in half for ease of handling)
Of course each half is six volts.. Those who talk about the need for the batteries to be Identical (Same make model, size, age and so on) are correct for the two half batteries that make up the six volt pair.
To draw (ASCII) it out
6V + 6v = 12 volt, (Both six v's need to be twins of each other)
6V + 6v = 12 volt (Both must again be twins of each other but may be different from the other two)
