Question for the Battery Experts
I have a pair of 6v CG batteries that I use to power the rolling home. Sam's Club, Ever-Ready's (220Ah). They will reach 3 full seasons about mid-season this year. They work flawlessly, and seem ag...

The variation in opinions seems to be around the compromise of adding 2 new golf cart batteries to the 2 old ones. You could shorten the life of the new ones. Some think it's worth it for the extra capacity you gain, others say not. It's not really a technical question, it is a risk for the money question.
Personally I would decide based on the condition of the existing batteries. If the specific gravity fully charged is near what it was when new, I'd do it and compromise the life of the new batteries a bit. If the old batteries show signs of getting old (low SG across the board that is uncorrectable, cloudy or smokey electrolyte, won't hold their voltage, won't pass a load test) then I would go for 4 new ones, or use just the 2 until they die.
You really do have the option too of charging different type or health batteries separately and drawing them down together. It is more work but it can get you that added capacity if you only need it occasionally.
