Anyone with head-to-head experience? I am needing to replace my main group 31 in my 100 series and am struggling with the trade offs. I have solar so shouldn’t deeply discharge the battery too often, but given I’m running a single battery system want to have all the insurance I can get. The Extreme series PC1250 is $534 out the door with a 4 year warranty at my local Autozone, but the Performance series 31M925 is $420 with a 3 year warranty. See spec comparison below, main difference seems to be the cranking amps. Odyssey rates the Extreme batteries to 400 deep discharges, but doesn’t say anything about the Performance series.
