Battery Group for 74 911?

[l_turn9]

I checked my OM but could not locate the Barrery Gr # - What works well?

I have a Group 48 in my 77, perfect fit with the factory hold-down.
Check the model numbers on your current battery, the group size might be encoded on the label.
For instance mine reads L3-H6-48CP

I believe the big version of the batteries is an H8….they are HUGE and heavy. Most of us run the H6. There should be bolt holes for both for he bracket to hold the battery in place.
