1 Odyssey Extreme or 2 Duracell platinum

Recommended Posts

I was planning on an Odyssey Extreme  34/78 Agm battery but can get TWO Duracell Agm batteries for the same price.



  • 20 amp hour rate:55
  • Battery electrolyte composition: Glass Mat
  • Battery purpose: Starting lighting instrumentation
  • BCI group size: 34/78
  • CA at 32 degrees F: 860
  • CCA at 0 degrees F: 750
  • Freight class: 65
  • Polarity:DT
  • Reserve capacity: 120



Cranking Amps (5 second start) 1500
Cold Cranking Ampms (CCA) 850
HCA 1250
MCA 1050
20HR Nominal Capaity (AH) 68
Reserve Capacity Minutes 135

Which would you choose? 2 Duracells or a Single Odyssey?



My system consists of a AutoTech 350amp alternator, Sundown 3k amp, Mosconi 240w amp, Helix 120w amp.
