hi

how "unhealthy" do you think it is to allow an alternator (in this case standard yanmar 3YM30 60 amp alternator) to run at max output for several hours at a time numerous times per year?

i.e. are these alternators designed for continuous high output?

thanks in advance

hi

alternator works fine now with two (nominal, likely quite degraded) Varta 110 Ah batteries and puts out max current only briefly even when batteries quite discharged.

want to change to three Enersys Odyssey PC2150 s, but they accept so much current when discharged, i'm worried about running my alternator at full output for, back-of-the-envelope-ballpark, 2 hours at a time multiple times per season if i do change to these.

cheers
