OPTIMA  BlueTop  Benefits

Starting and dual purpose (starting and deep cycling) models available. Lasts up to 2 times longer than other batteries. More power in the initial 1, 3, 5, and 10 seconds of the starting process than comparably rated conventional lead acid batteries. Constant performance quality keeping your battery running at the same level even as it's being discharged. Ideal for seasonal use, fully charged, it can sit unused for up to 12 months at room temperature (or below) and still provide the power necessary to start your boat's engine. 15 times more resistant to vibration than other batteries. Nonspillable and can mount in almost any position.

 

 

 

 

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.
