Battery voltage drop speed

Is a battery healthy if drops under 10 volts with load?

If you put a load on the battery with a dead cell, then release the load, you''ll see the voltage down around the 10.5vdc arena, not while under load. If yours is going back to 12-13vdc after the load is release, this is not your issue. I''ve never tested to see what the voltage drops to under load for a healthy battery. –
