FAULT
POSSIBLE CAUSE
REMEDY
Mechanical damage to

(DISASSEMBLY and
ASSEMBLY)
Indications of link overheating
Loose terminal nuts
Check torque
Cell with abnormally high
voltage at start of charge
Cell dry or insufficient
electrolyte level
As soon as the fault is observed add
10 cm
3
of distilled water to the cell.
Do not adjust precisely until the end
of charge
NOTE: A cell charging with
insufficient electrolyte may also
show considerable temperature rise
Main charge cut off voltage
reached before minimum time
or not reached at the maximum
time
Battery not fully discharged
or strongly unbalanced
Perform a regular check (CHECK)
Cell with abnormally low
voltage at end of charge (Less
than 1.50 V)
Exposure to high
temperatures, high charge
rates or separator damage
Replace cell (DISASSEMBLY,
ASSEMBLY)
Low capacity cell (reversed
polarity, or a normal polarity
voltage of less than 1 V at the
end of a 64 minute discharge at
40A)
Normal wear after long
service
Perform Regular Check (CHECK)
Replace with new SAFT cell
