Eevo that is probably right as they will lose capacity with age so it depends on how they have been maintained/used and how old they are.
Those specs I posted are for 'new' and are the ideal or perfect scenario.
As said earlier by someone anything that holds 12.6v or above is good. And has a high SOC.

well i just got a new yellowtop today under warranty.
when (if) it stops raining i'll go test it.
