I am also thinking I will get the auto start module for my inverter while I am at it.

The sticker only indicates the date when they were last charged. It is NOT the build date. The manufactured date is stamped in the case somewhere.

UPDATE:
Got my new batteries in the watering system installed. I decided to have 2 separate "circuits" for the watering system and not connect all 4 batteries together. Seems less prone to error and only makes watering take 45 more seconds. What a nice setup! I was able to fill them until the bulb got hard, which was very little as expected for new batteries, yet enough to give me confidence it purged air and works!

Not much point in getting all enthusiastic about new batteries unless you know that your charging system is capable of doing a 100% job of charging and maintaining the batteries. Many old systems - especially single stage converter units - were never any good and some actually killed the batteries instead of caring for them.

Watering system? Hardly needed if the charging system is a good one.

Love my watering system. Takes longer to get out a bottle of water and the hand pump than it does to actually fill the batteries.

Most common six volt battery is 230 amp hours. A pair of them in series is a 230 amp hour 12 volt battery. Think of it as a 12 volt battery please..

Now: 12 volt batteries:
Group 24, about 75 amp hours
Group 27, Just under 100
group 29, Just over 100

So far a pair of sixes beats a pair of 12's That will now change
Group 31, about 130
Group 4D around 240 (lifeline AGM)
Group 8d 255, (Lifeline AGM)

Of course there are other six volt batteries as well.
Check out this one
Lifeline Batteries - Marine & RV Deep Cycle Batteries

But usually when folks talk about six volt batts they mean a GC-2 Golf Car 220 to 230 amp hour
