We replaced our Oct 2006 this year (2014) but if used on a golf course we would have had to replace in 2012. Six years is pushing the limits on this technology.

I don't have correct detail on this, but maybe somebody here can explain how they do it.

The golf car dealer where I got my used T-1275s was using a measurement in time the batts would last while driving around. Once the four batts (with 12v T-1275s) or 6 batts (using 8v batts) could not last that long, they swapped out all the car's batts and put new ones in. The golf car dealer and I gather golf courses, have some sort of meter measuring gizmo that simulates driving around so they can measure the time the golf car is good for.

ISTR the cut-off was 100 minutes minimum? My used ones were marked as 86 min. When I did my load test for AH it came out in the mid-80% of original AH rating, so the golf car method seems to get about the same % or else that 86 of 100 was a coincidence if the car when new gets way more than 100 ---I don't know how that all works. (I then "recovered" them to 90% and they are still good)

Anyway golf courses have their own way to know when to replace the batteries, and it is different from the way RVers decide that, where there is no exact cut off for an RVer where some will keep using a battery that has lost x in capacity, while others will toss it.

RVers do not all have the same fixed time like a golf car has to last for a game or two whatever it is those guys use to decide.
