Pulse Discharge
The graph titled ODYSSEY® pulse discharge per battery shown below demonstrates the extraordinary short duration (pulse) discharge capabilities of the ODYSSEY® family of batteries. Note that the discharge figures are shown for an ambient temperature of 25°C and to an end of discharge voltage (EODV) of 7.20V per 12V battery.
ODYSSEY®
pulse discharge per battery
Two points should be kept in mind when using this battery for such extreme high-rate discharges. First, sufficient time must be given between two successive discharges to allow the terminals to cool down. Second, the graph reflects the capabilities of fully charged ODYSSEY® batteries. Unless the batteries are fully charged, one must not expect them to meet these numbers. Finally, all of these numbers are for an ambient temperature of 25°C; if the temperature is significantly different from 25°C, the graph shown above must be appropriately modified.
Table I below provides the five, ten and twenty second pulse discharge numbers for the ODYSSEY® line of Drycell™ batteries.
