Another battery question

[pectoralfin]

A new pair of 300 engines were just put on the boat. I was reading the manual
regarding battery requirements. I presently have Odyssey batteries (34m-1500) which have a reserve capacity of 135 minutes while the manual requires 160 minutes. All the other requirements are met. Are these ok or do I have to get new batteries? Thank you for your assistance.

These are just the cranking batts? - you have one or more "house" batts?

IMO, If the batteries meet/exceed the recommended CCA /MCA numbers, I can't imagine that difference in "reserve capacity" minutes matters.
