I need to replace three coach batteries. What is the minimum CCA rating per battery that would work as a temporary replacement for a year or two. Also are group 34 batteries acceptable.
Thanks, Mike
If you are talking about the chassis batteries, for starting and other automotive functions, the answer is yes.
Three of any new BCI 34 batteries will be enough power. Two group 31 batteries would also be enough. The 31's are usually around $100 at a truck dealer. If not already done, your rack will need to be modified.
Here is the page from the M11 manual regarding battery CCA recommendations.
Thanks, just what I needed.
