(B) Selecting battery type on your charger
Although it is not possible to cover every type of battery
charger available today, this section gives the ODYSSEY
®
battery user some general charger usage guidelines to follow,
after the charger has been qualifed for use with this battery.
In general, do not use either the gel cell or maintenance free
setting, if provided on your charger. Choose the deep cycle
or AGM option, should there be one on your charger. Table
5 below gives suggested charge times based on charger
currents. As previously indicated, deep cycling applications
require a minimum 0.4C
10
current available from the charger
so the values shown in Table 5 do not apply to all products in
all applications. To achieve maximum life from your ODYSSEY
battery after completing the charge time in Table 5, we
recommend that you switch your charger to the trickle charge
position and leave the battery connected to the charger for
an additional 6-8 hours. The trickle charge voltage should be
13.5V to 13.8V.

Temperature compensation
Proper charging of all Valve Regulated Lead Acid (VRLA)
batteries requires temperature compensation of the charge
voltage – the higher the ambient temperature the lower the
charge voltage. This is particularly true in foat applications
in which the batteries can stay on trickle charge for weeks
or months at a time.

The charge times recommended in Table 5 assume that
the ODYSSEY battery is fully discharged and these charge
times will only achieve about a 80% state of charge. For
partially discharged batteries, the charge times should be
appropriately reduced. The graph in Figure 2, showing
OCV and SOC, must be used to determine the battery’s
SOC. The battery should be trickle charged after high rate
charging, regardless of its initial SOC.
*PC1220 no longer distributed in the United States.
The temperature compensation graphs for ODYSSEY
batteries in foat and cyclic applications are shown for
ambient (battery) temperatures ranging from -40°F (-40°C) to
176°F (80°C). The compensation coeffcient is approximately
+/-13.3mV per 12V battery per
o F (+/-24mV per 12V battery
per °C) variation from 77°F (25°C). Since the charge voltage
and ambient (battery) temperature are inversely related,
the voltage must be reduced as the temperature rises;
conversely, the charge voltage must be increased when the
temperature drops.
Note, however, that the charge voltage should not be
dropped below 13.2V as that will cause the battery grids
to corrode faster, thereby shortening the battery life.
RAPID CHARGING OF ODYSSEY
®
BATTERIES
All ODYSSEY batteries can be quickly charged. Figure 7
on the next page shows their exceptional fast charge
characteristics at a constant 14.7V for three levels of inrush
current. These current levels are similar to the output
currents of modern automotive alternators. Table 6 and
Figure 7 show the capacity returned as a function of the
magnitude of the inrush
3
current.
Standard internal combustion engine alternators with an
output voltage of 14.2V can also charge these batteries.
The inrush current does not need to be limited under
constant voltage charge. However, because the typical
alternator voltage is only 14.2V instead of 14.7V, the
charge times will be longer than those shown in Table 5.
3 Inrush is defned in terms of the rated capacity (C
10
) of the battery. A 0.8C
10
inrush on a 100Ah battery is 80A.
