Odyssey Optimizer information:

CONSTANT CURRENT BULK CHARGE: Constant current charging is the fastest way to charge any battery; however, constant current can also overcharge a battery easily if it is not controlled properly. With the ODYSSEY OPTIMIZER, constant current is only used until the battery is approximately 80% charged. At this point a constant absorption voltage is applied. Unlike most chargers, the full rated current is maintained until the battery reaches the absorption voltage (true constant current).

CONSTANT ABSORPTION VOLTAGE CHARGE: This voltage is a precision high-rate voltage that allows the battery to safely reach a full charge in the quickest time. This voltage is held constant while the charge current decreases as the battery accepts less current. Overcharging cause's degradation of battery characteristics; to prevent this, the charge is terminated based on an adaptive timer. The time spent in the absorption mode is proportional to the time spent in the constant current mode and is based on three times the time spent in bulk, or 8 hr maximum, with 1 hr minimum. When the absorption timer expires, a constant float voltage is applied. At this point the battery is 100% charged. CONSTANT FLOAT-VOLTAGE CHARGE: This voltage is a precision low-rate voltage. This voltage is low enough to prevent overcharging, but high enough to allow the battery to replace its standing losses and maintain a 100% charge. When not in use, we recommend the battery be left on the charger to receive this float charge.

TEMPERATURE COMPENSATION: To maximize battery life, a negative charge temperature coefficient of approximately 3.5mV per cell per °C variation from 25°C is used during the float charge mode. A precision temperature sensor monitors the ambient temperature. As the ambient temperature increases the float voltage must be reduced, and vise-versa. The minimum charge voltage is limited to 13.2 volts. This helps offset the impact of high temperatures on the float life of the cell.

REVERSE POLARITY & SHORT CIRCUIT PROTECTION: If the attachment harness in accidentally reverse connected to the battery, or the output leads are somehow shorted (off the battery), the ODYSSEY OPTIMIZER will be electronically protected - there are no annoying fuses to replace. The output is not energized until a properly connected battery is detected.

INDICATORS: Indicators for charge mode (yellow) and ready mode (green) are provided. The charge LED lights whenever a battery is properly attached and charging. It will light continuously when the charger is in bulk mode (constant current) and will flash when in absorption mode (constant voltage). When the charger enters float mode, the charge LED will darken and the ready LED will light. With no battery properly attached, both indicators will remain dark.

STANDARD OUTPUT CABLE AND CONNECTOR: The output cable is parallel cable six feet long and has a fully- insulated, polarized, quick-disconnect plug. It is fixed to the enclosure using a strain relief. A quick-disconnect attachment harness with ring terminals is provided.

STANDARD INPUT CABLE AND CONNECTOR: The input cable is six feet long and has a NEMA 5-15P grounding plug for use in North America. It is fixed to the enclosure using a strain relief.

HEAT SINK ENCLOSURE AND MOUNTING: The ODYSSEY OPTIMIZER is provided with a heavy-duty, extruded aluminum heat sink enclosure with aluminum back and end plates. Mounting slots are provided for wall mounting the unit.

This Odyssey Optimizer is recommended for PowerSport applications. There are two types of chargers for powersports applications, depending on the way the battery is used. The first type is the cyclic use charger, required in situations where the battery will be deeply discharged each time and must be recharged relatively quickly. All recommended chargers can be connected and operated indefinitely.

The second type is the storage use charger, required when the battery must be maintained at a high state of charge. Custom V-twin motorcycles are a typical application requiring this type of charger. These bikes are typically ridden for short distances and the battery has to provide multiple starts. Several days' of this type of usage causes the battery to fail prematurely due to insufficient charge. A storage use charger must be connected to the battery whenever the bike is not in use. This will keep the battery at a high state of charge and eliminate premature failure due to repeated undercharge.
