Purchased 3 new batteries from Travis at TS Marine:
2 x Deep Cycle House battery – Hella Endurant Cyclemaster MDC31/130 – Flooded Lead Acid 130 A/Hrs each, 24 month warranty.
1 x Cranking Start battery. Hella Endurant Boatmaster MMF27/780 – CCA 780, MCA 910 Maintenance Free , 24 month warranty.
Cold Cranking Amps (CCA) is the maximum load the battery can handle at 0 degrees F for 30 seconds without falling below 7.2 volts. Marine Cranking Amps (MCA) is the same test conducted at 32 degrees F and is usually somewhere around 125% the CCA rating.
Travis gave best price after my shopping around.
