Out of the Odyssey manual:

1. Bring the battery to room temperature—25°C (77°F)—if it
is not already there.
2. Measure the open circuit voltage (OCV). Continue to step
3 if it measures at least 6.00V.
3. Charge the battery for 24 hours using a constant current
charge that is 5% of the 20-hour capacity of the battery
(5A for a 100Ah battery). The charger should be able to
provide a driving voltage as high as 18.00V. Monitor the
battery temperature; discontinue charging if the battery
temperature rises by more than 20°C.
4. Allow the battery to stand for 18 hours after completion
of step 3.
5. Perform a capacity test on the battery and record the
amp-hours delivered. The longer the discharge the more
reliable the result. This is Cycle 1.
6. Repeat steps 3 through 5. The capacity noted in step 5
is the Cycle 2 capacity. Proceed to step 7 only if Cycle
2 capacity is greater than Cycle 1 capacity; otherwise
replace the battery.
7. Repeat steps 3 through 5 to get Cycle 3 capacity and
proceed to step 8 only if Cycle 3 capacity is equal to or
more than the capacity in Cycle 2. Replace the battery
if Cycle 3 capacity is less than Cycle 2 capacity. If the
capacity is greater than or equal to 80% of the rated
capacity of the battery it may be returned to service.
8. Recharge the battery and put back in service if Cycle 3
capacity is equal to or exceeds Cycle 2 capacity.
I've always been impressed by the mystical practices associated with Odyssey batteries.
