Cell by cell, 2-volt readings, will know all, tell all. Resting or under load as long as the load is constant.
Australia. Christmas is broiling, August it freezes. Storms spin the wrong way. I forgot if you speed-shift using the left hand. I'll bet they even arrange their poker hands from low to high. The biggest attraction is a huge rock. And no way in hell is a Rolls & Surrette going to have 1.300 SG unless you got polar bears staring in your window.
My bank is 6.5% antimony. 15 volts is too high to end up with every day. Stop the flow of electrons when the bank requires 2% of total ampere hours of current at Fourteen Point Five Volts. Remember, these are different animals than an RV battery. High voltages cause antimony to pack it's bag and run away to join the negative plate. Top charging will minimize dendrites (mossing) but he has to get a handle on the high voltage. Whenever I encounter top SG in all cells escept a bad one it's a siren going off about too high voltage.
HYDROMETER ACCURACY
"But occifer, my speedometer is more or less accurate. Waddaya mean a three hundred dollar ticket?"
This is not "Lick the nine-volt and see if it's bad" time. Good instruments, a little intelligent time spent or pay-the-piper. His choice. Or he can work a thousand hours paying for a dozen hours of missing battery management.
Or if all else fails, contact Rolls and let him hear the proper volt/F absorbsion limit.
