Figure 2 shows the relationship between open
circuit voltage (OCV) and state of charge (SOC) for
the ODYSSEY
®
Extreme Racing™ battery.
(A) How do I know the state of charge of the
battery?
Figure 2: ODYSSEY

Extreme Racing™
Battery OCV vs. SOC
As long as the battery has not been charged or
discharged for 6 or more hours, Figure 2 can be
used to determine the SOC of the ODYSSEY
Extreme Racing battery. Use a high quality digital
voltmeter to measure its OCV. The graph shows
that a healthy, fully charged ODYSSEY Extreme
Racing battery will have an OCV of 12.84V or
higher at 25ºC.
(B) How long can the battery be stored?
Refer to Figure 3 below. At 25°C (77ºF), these
batteries can be stored for up to 2 years. The
lower the temperature, the longer the storage time.
The battery must be charged before storage.
Roughly every 10°C (18°F) increase in temperature
cuts storage time in half. If the temperature rises
to 35°C (95°F) the battery may be stored for only 1
year before a recharge becomes necessary. Figure
3 will apply only if the battery is fully charged
before storage.
