Sorting through the garage a couple of days ago I found I have three batteries for the Raptor. So I've charged them all up and have been checking them in the mornings to see their respective rates of voltage drop. So the question is what voltage would you expect a good battery to be able to maintain & for how long? All three started out at 12.6(ish) and over a few days one is at 12.49, another at 12.4 & the last at 12.57. My thinking is only the latter one is worth saving.
I'd give them all a load test and see how well they recover their respective voltages. That load being something like a bike starter motor.
