I had to go out of town for the week. When I got back the battery in my car was dead. I got a jump and had the battery checked and it was charging fine. The battery is brand new and so is the alternator so they otta be good.
I parked it last night and now about 12 hrs later it is drained again.
There is something draining the battery while it is parked but I can't tell what it is and I don't know how to check.
The only things that I can think of that could be related to this problem may be that I was trying to re-set the dashboard clock after replacing the alternator and battery and both buttons now stick so the clock continues to cycle through hr and min while the car is on.
Also the day before I left I cleaned the engine compartment with degreaser at the local DIY carwash. There was a lot of grease, oil, and everything else everywhere from years of various leaks. I did cover anything (electrical,intake,fuses) that looked important with tinfoil like the directions state on the can.
The engine looks great now but the car won't start.

What kind of car is it? Accord? Civic?

I had a similar problem on my family's Camry after I changed the battery. After days of this problem and several consultations with a mechanic, we realized the cause: the battery cables weren't connected tightly enough to the terminals.
Apparently, the battery can transmit energy well enough with a loose connection, but it is difficult to recharge via alternator if the connections aren't supertight. Check that first.

Today I fixed the problem with the clock buttons sticking while waiting for the battery to charge off a jump (which took forever). I am letting the car run for like a half hour to see if it charges the battery back up. Then I am gonna let it sit for a half hour and see if it restarts.
Maybe fixing the clock buttons will do something. My terminals are clean and cranked as tight as they can go (i can still pull both off by hand with a little effort though).
I am gonna get a test light today. Should I be getting a multimeter instead? I have never used either.
By the way this is a 91 prelude SI 2.0

test lights are...worthless. the ONLY thing they tell you is that there is voltage. but in this case that's probably enough. check for voltage being conducted when the car is off, and you'l probably have a short to power or ground on that circuit so that its constantly using power it shouldnt. since the battery is new, it shouldnt have a surface discharge problem, just a parasitic drain from a short, if not shorts.

Is this battery a Honda OEM replacement? Could it be that the battery posts are too small for the terminals? The terminals should NOT be able to be pulled off without loosening the terminals. If they are still slipping then that could be your problem.

It turns out that the clock was the source of the drain on my battery. It was stuck scrolling through hour and minute settings even with the car shut off. Apparently this was enough of a draw to kill the battery over several hours.
Thanks for the input guys.
