Capacity of ACDelco Voyager M27MF battery

[owlybear]

Does anyone know the C20 capacity of ACDelco Voyager M27MF batteries? Those on my boat have a label stating 95Ah (without specifying the measurement method) while searches on the internet invariably mention a value of 105Ah, again without specifying the measurement method. I'm guessing that the lower value is the C10 capacity and the higher one the C20 value but I would like to be sure, in order to input the appropriate value to my battery monitor. I've tried emailing various firms, including ACDelco themselves but haven't even received an acknowledgement from anyone - very frustrating!
Thanks in anticipation

If you don't get an answer, I would go with the lower figure - You will be less likely to get a surprise - also as batteries age their capacity drops, so you need to allow for that as well.
