What is the spec for the MCA and CCA for these enginines. I am looking to use dual purpose batteries because I have electronics on board. I am looking atthe DEKA 27M which is a dual purpose AGM battery the specs are 580 CCA 900 MCA and 92 ahr. Thanks
That battery has too little capacity for the G2 engine.
800 CCA (1000 MCA) 12 volt - including operation below 32°F (0°C)
NOTE: Under extraordinary electrical load or environmental conditions, use a 107 amp-hour minimum battery (generally available in group 29 size).
