Check to make sure nothing inside the car is on ashtray light,gove box,mirror
that could cause the battery to drain.Phil

Hi,

Here's a problem I had which I have fixed. Maybe the solution will
help you.

93 GXE 140k miles

Had nearly 30 days of continuous below-freezing weather where I am,
Washington DC suburb. Drove one to local mall a few miles away. Came
out after about two hours, battery is completely flat, will not turn
engine over. I figured it was the cold weather, many cold starts,
heater running constantly, often using headlights, short, start/stop
runs.

Called my wife, she brought her car with jumper leads, started OK.
Drove the car home and put the battery (only 18 months old) on the
charger overnight. Reconnected it next morning, car starts and runs
fine. Assumed the problem was solved. Next day I get a call from my
wife, Maxima has flat battery outside local library.

Same procedure, jump start then drive home. Took the battery out and
put it back on the charger. Left the car till the weekend for further
examination.

On the weekend, looked up my Haynes manual. Started doing their
charging system checks.

1) All fuses inside car OK
2) All relays under hood OK]
3) Battery open voltage OK
4) Put an ammeter in circuit with the battery (disconnect negative
battery terminal and insert ammeter) Found that with the IGNITION OFF
there was a 100 milliamp current drain. Haynes says the maximum
current drain (considering, clock, radio presets, engine control
computer, etc) should be 50 milliamps.

With the ammeter still in circuit I started pulling connectors off the
positive battery terminal. As soon as I removed the fuseable link
which connects to the alternator main terminal, the current drain
dropped to zero.

If in your case it is not the alternator that is producing the current
drain then try removing fuses to see if you can find the circuit which
is causing the problem.

I had a problem where the battery was being drained by a bad relay for
the radiator fan. The fan would run forever after I shut down the car
until the battery was drained. The fan isn't real loud, so there were
times when I was in a noisy place and I didn't notice that it was still
running.

I can't beleive it, you just described my problem!  I have a 96 Maxima with
approx. 150,000 miles.  About 1 month ago, I tried to start the car, and
nothing happened .  We hooked it up  to the charger and it started and
cleaned up the tiny bit of corrosion from the post.  It has been running
just fine until today.  I went to start it and again..NOTHING.., I used
the charger & in less than 5 minutes, was able to start it.  I drove
straight to the local Auto Zone to have them test the battery.
(Unfortunatly, there was not enough personnel so, they said to return in
an hour).  I made 3 more stops and it started perfectly each time.  I made
1 last stop before going back to have my battery checked, and I got nothing
when I went to start it.  I had to have someone jump it off for me, and it
took about 10 minutes to even start.  The battery tested full at the Auto
Store but required a jump start for me to leave.  The clerks opinion was
that the problem is the cylinoid on the starter.  I called my mechaninc
and he said probably not the starter.  I just dropped my car off and
hopefully, tomorrow I will know the problem.  I'll be sure to post and let
you know what they found, and I'll be checking to see if you found the
problem, in case my car isn't fixed.
