Wow, I would say the battery has had it. I do have a concern regarding your TT's main fuse by the battery. I would think that it would have blown due to the current that was being drawn by the defective battery. You may want to check out why it did not blow.
Before you leave the NEW battery hooked up to the TT's charge controller for an extended length of time, monitor it for awhile during the day, when you can check the status each hour. Unplug the shore power over night until it checks out. Plug the TT back into shore power in the morning and it should recharge your battery by noon.
If the battery is charging properly (check voltage), and the battery/wires are not getting hot, you can leave the TT plugged into shore power between outings. Just keep checking the batteries water level on the first day of each month. I have it in my TASK list on the tablet to automatically remind me.
