Just to make sure we are all talking about the same thing:
The "clamp type" multimeter uses alligator clips to clamp onto the battery
terminals....not a clamp that goes around the wire? Sorry if I am being remedial.
The 17 volts is per battery
, or per set in parallel.
Are you charging
from a motor
or solar panel?
17v sounds a bit high for lead-acid battery doing a normal charge. An equalizer might hit that high per battery. If that were the case the batteries should be fully charged.
One thought, you might have an open or dry cell. That could explain high voltage during charge and low capacity and voltage under load.
