In any event, if you have a mystery battery drain like that and it isn't obvious, I'd recommend taking off the negative battery cable and put an ohmmeter between the disconnected negative cable and ground. It should read infinity, or very high, or open. If you get something less than 1,000 ohms, start looking for frayed wires, accessories left on, something. (That's for a negative ground system which is original)

If the battery fails and you have over 1,000 ohms, you have a bad battery.

I was of the opinion that positive ground was the original.
