6.
Raise the voltage to the maximum value permitted by the equipment as shown in Table
8.1.
Table 8.1 lists the hours of freshening charge to be given
after
charge current has
stabilized for 24 hours. Freshen charge must be given at a voltage high enough to
cause gassing/mixing of the electrolyte. Do not charge at voltages higher than in Table
8.1.

Table 8.1 applies for cell temperatures between 60
o
to 90
o
F (16
o
to 32
o
C). For cell
temperatures 40
o
to 59
o
F (5
o
to 15
o
C), use twice the number of hours. For cell
temperatures 39o F (4o C) or below, use four times the number of hours.
On “C," “D,” “E,” “F,” and “G” cells, you may insert the thermometer in the funnel of the
pilot cell's flame arrestor and leave it there by adjusting the rubber washer to the correct
height and leaving off the dust cap.
DO NOT LEAVE thermometers in place in
seismic regions.
7.
When charging current has decreased and stabilized (i.e., no further reduction for 24
hours), charge for the hours shown in Table 8.1.
Monitor the battery temperature during the charge. If the battery exceeds
110
o
F
(
43
o
C)
, stop the charge immediately and allow the temperature to
decrease below 100
o
F
(
38
o
C
). Failure to follow this warning may result
in severe overcharge and damage to the cell/battery.
