So long story short, my bike died, it was an old battery so I bought a new one. The first day riding it, it died after about 45 mins of riding. Luckily I was near a mechanic and had the battery/stator/rectifier regulator tested and he said the RR was bad so I replaced it yesterday with a used one. Jumped the bike off last night, rode it around a little bit (6 miles), and it was keeping charge after that. Plugged it into my battery tender, went to bed, woke up this morning, and turned the key on and everything instantly dimmed out and died completely. Is my battery screwed? Do the battery tenders work just as well as a regular battery charger? It said it was in storage mode all night so I would assume that means it is fully charged. I am at a loss for what to do next, so any help would be appreciated.
