There is no need to go full discharge. The voltage and capacity properties of a lead-acid battery have a near linear relationship so a 50% discharge is fine for testing. That should be 11.6v. All of this is just a comparison. A brand new battery might show +/- 10% of the labeled rating. That do

If you have the original battery Reserve Capacity specs it is an acceptable quick test to see if the battery is good but maybe worn or at end of life. If possible test the battery(s) individually, Charge fully, bring battery to around 80F and time how long it will sustain a 25 amp load before re
