A couple weed ago I noticed my 2000 Protégé (1.6) was cranking progressively slower during startup. (I bought the car used over a year ago and had no idea how old the battery was.)
The alternator seems okay because once it’s started the car run fine with full headlights, etc.
This past Sunday, after having sit for two days, there was nothing when I turned the key, not even a click.
I replaced the battery Sunday night with a new Die-Hard and Monday morning it started fine and cranked hard.
Now this morning, (Tuesday) the battery is completely dead.
Anyone have any ideas what could suddenly be draining my batteries?

Thanks in advance.

Did you test your alternator, starter and associated wires before going after the battery??
