That's right. Or, the tender wasn't connected securely. There are all kinds of possibilities. Particularly since he said he did get it running, but then it died on him before he had a chance to see if the battery was taking a charge.Well yes I think he HAS. Unless his tender has failed, that is.
I don't see a problem with him replacing the battery if that's what he wants to do, but he seems to think he needs a 'better' battery for some reason, as if that will solve everything that might be wrong.
