Marine Calculation Information Calculate AmpHour Needs for Marine & RV Accessories "I've got a fish finder, extra lights and a trolling motor. How many batteries do I need to stay on the water for a period of time?" Calculate the Ampere Hours for each power need: (amps x # of hours = Ah) Example: - Lights 5 amps x 4 hours = 20 Ah - Fish Finder 1 amp x 4 hours = 4 Ah - Trolling Motor 10 amps x 4 hours = 40 Ah __________________________________________ Total Calculation Equals 64 Ah @ 4 hour rate Calculate AmpHour From Pound Thrust of Motor (General rule of thumb to estimate Ampere Draw) "I've got a motor with a certain pound thrust. What total amp draw does that equal?" Calculate the Ampere draw based on the pound thrust of the motor: (Pound Thrust / Motor Voltage x 12 = Ampere Draw) Example: - 55 Pound Thrust / 12 volt x 12 = 55 Amp Draw - 55 Pound Thrust / 24 volt x 12 = 27.5 Amp Draw - 55 Pound Thrust / 36 volt x 12 = 18.3 Amp Draw ______________________________________________ *# of OPTIMAs® connected in series for 24 volt = 2 *# of OPTIMAs® connected in series for 36 volt = 3 Examples of typical accessory loads: Blue Top Type: D34M / D31M These batteries are dual purpose. They are designed for engine starting and deep cycling applications and for use in boats with large accessory loads. Recommended charging information: Alternator: 13.65 to 15.0 volts, no amperage limit. Battery charger: 13.8 to 15.0 volts, 10 amps maximum, 6-12 hours approximate. Cyclic Applications: 14.7 volts, no current limit as long as battery temperature remains below 125°F (51.7°C). When current falls below 1 amp, finish with 2 amp constant current for 1 hour for D34M and 3 amp constant current for 1 hour for D31M. Rapid Recharge: Maximum voltage 15.6 volts (regulated). Maximum current: No limit as long as temperature <125°F (51.7°C). Maximum recharge time: Charge until current drops below 1 amp. Float charge: 13.2 to 13.8 volts, 1 amp maximum current, time indefinite (at lower voltage). All limits must be strictly adhered to.
