Well I killed my battery this week. I have a cheap tender, yes I know Anyway, I left the tender on the battery for about a week and moved my bike last night because I have inspectors coming over today to review the house for my buyers. Took the cover off, disconnected the tender and when I turned the key, nada, nothing, not even a single light. Dead as a hammer. Question: Can I jump it and then ride her to charge it back up and be ok, or is my battery toast and need to be replaced? It is less than a year old.
