2005 accord won't start

I've searched the forums but just see possible solutions for older accords.. The problem started a month or so ago... seemed like a bad battery .. it would crank, then stop (like a dead battery) .. I'd then turn key back and try again and it would start right up... well, I went to Advanced Auto and they said I had a dead cell in my battery.. OK, new battery.. good for about a week.. then same issue.... well, it was off and on ... NOW.. (after having battery, alternator and starter checked) it won't even crank over ... Power comes on, lights work fine etc... every so often it barely tries to push the starter, but not much... it is just simply like a total dead battery (which I know is not the issue).... any suggestions??

Thanks!

Try to check for parasitic electrical leak. You need to connect the meter in series with the battery. I believe the numbers more than .5 mili amps will tell you that there is an excessive consumption somewhere.

Did you happen to install something new, like new radio or something that may use some juice?

Good luck,
