Was that Odd or Odessey??? lol

Optima's dont have a higher enough ah rating for D3/4.

Odyssey in the primary. Optima in pos 2 & 3.

You won’t fit the D31 into the main area...

is ah really that relevant for a cranking battery though?

Fitted a Centary DIN85L CCA780 to my 2.7RRS 3 1/2 yrs ago and not a problem .

For these vehicles it is, the OEM battery in mine is rated at 92AH.

Not so much... the cca is important on Calcium/Lead batteries.

The pulse current on the Optima/Odyssey more than exceeds the required rating.

However they do chew a bit in standby so a decent AH doesn’t hurt [emoji6]
