I'd be surprised if 2 Battery Tenders were bad. Check to make sure the charger harness on your bike is tight and clean & if there's an in line fuse, check that as well. Also check to make sure there isn't a bunch of crud on the pigtail end of the bikes harness causing a bad/weak connection. If all else fails get your battery load tested. Every once in awhile someone gets a bad battery. Also, do you have anything on the bike that may be causing a drain, like security, extra led lighting etc?
