Left the lights on while car was off ~1 week ago. Started up after a
while, and drove it for ~30 minutes to replenish the battery. As of
late (can't remember if it was before or after this happened) the
voltage seemed to be a bit higher on the meter then usual.
Yesterday morning, started her up, check engine light was on, then or
later another light came on (why can't I remember these things?). Ran
it around that day. This morning it started up, didn't drive it. About
an hour later it was dead. Put a new battery in, started, ran it,
needle dips down when ANY accessory is put on, even when you put the
radio on and crank the volume up some. The needle seems to be where it
should be at times, other times it's low (I don't know, 10 volts
maybe). Haven't put a meter on it yet.
I had a problem like this in the past, and the problem turns out was
a blown fuse. I checked nearly all the fuses yesterday evening, and
that didn't seem to be the problem.
Possibilities? Many thanks for your input.

the voltage at the battery should be 13.2 volts with the engine off.
The voltage at the battery should be about 15 volts with the engine
running. Check it with a volt meter. If the battery is dead, it is
better to put the battery charger on over night instead of just
relying on 30 minutes of driving to charge the battery.

This isn't accurate. A fully charged 12v car battery should read 12.6
volts with the engine off. With the engine running it should be
between 13 and 15 depending on the battery's state of charge and the
electrical demand.
