Anytime I hear the term "Battery Tender" I cringe! Batteries are not designed to be constantly charged 24 hrs a day for weeks on end. I work for a company that sells batteries and they love battery tenders because they harm the battery beyond repair. You are better to remove a fully charged battery for the winter than using a 2 amp charging system cause even at 2 amps it only takes a few hours to completely charge a small battery. The rest is boiling the battery over... I just bought a 86 Venture and got $400 off the price because it wouldn't start even tho the tender was hooked up for the last 2 years. Different battery and it starts everytime. Anyways... if the bike is running it should show a charge on the volt meter of 12.5 - 13.5 volts if the battery is shot because it can never catch up... but if the volts are dropping off it could be a bad stator or your battery is storing a "surface charge". If you are getting it tested, all ways put the battery under load 2 times and go by the second. The first one can give you a false positive and most of you know from high school... a false positive can be HORRIBLE!!!!
