I bought the Big Crank last fall. Ran it all the way down twice and it won't hold a charge anymore. (I bought a Battery Tender and it only charged it for two hours before showing that it was full. It started up when I put it on the Savage, but the next morning it was dead).
Strange,......in RV use, AGM batteries will take a lot of abuse, more so than regular lead acid. I hope it really is the battery at fault,.....if you're junking it.
