Battery question

[hkreck]

Ok my batteries are going on 5 years old now, over the Winter I had them on a battery tender but it never showed them being fully charged. Yesterday I check them with a Hydrometer and they showed in the green. I then check the voltage on a multimeter and they showed 12.60. I was thinking I needed new batteries this year but now I'm wondering if I do or not? One thing we don't dry camp so how much do I really need fully charged batteries? Any thoughts?

Numbers look OK. Why not take them to auto parts or battery store for a load test before you buy new ones.

They are charged, this is not a question. Do you boondock, how much do you need them. The SG (and to some extent the voltage) indicate maybe 90% SOC. The real question is what is the capacity and neither measurement will tell you that. You can load test them or you can just leave something on and see how they do.
