Yes, it can have a dead cell or something can be on pulling power from the battery. Batteries are just like people: Some live longer than others, but they all die eventually. A dead battery can indeed be an alternator problem, but is much more likely to just be a battery that reached the end of it's useful life.

Why does my Car stall when you unhook the battery?
It means that you have an alternator fitted. An alternator needs an amount of battery voltage to generate electricity. A generator/dynamo will make voltage without a battery being present.
What is wrong with my 1986 300zx if when I take the jumper cables off the car dies and my battery is brand new?
Your alternator has failed, and the battery has drained from running the vehicle without being able to recharge it. Replace the alternator and the battery should be fine.
Im on your third alternator battery stays strong but something continues to kill the alternator ive taken the fuse out of the radio have a new starter and alt belt so?
Kills alternator? don't you mean kills battery? Installing a new alternator without first charging the battery well (2amp for 8hrs) will quite likely burn up a new alternator as well as being hard on the battery.
Battery light on on 2003 Ford Expedition?
Your battery is not being charged because of a problem with the charging system Whether its a problem with the alternator / voltage regulator , the serpentine belt etc . you should have the charging system checked
You have a brand new battery it discharges right after it is charged again is it the alternator?
Assuming the new battery is good! The usual problem why a battery is not charging is the alternator. The battery will be discharged if the alternator is not working properly when you start the engine and when the engine is running, etc. The vehicle uses the batteries electricity instead of the alternators electrical output, and of course if the battery is not being replenished by the alternator the battery will fail in a short period of time. You should test the alternator to see if it is putting out between 12 and 15 volts. Another possible things that could be the problem with a New battery failing so quick is, maybe the proper amount of acid was not put into the battery, a short in the wiring, etc.
Your alternator and battery both tested good but the battery is not being charged?
Most likely cable running from stud on top of alternator to battery terminal is corroded or broken.
Why is your car not starting and the battery keeps dying?
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.

What does it mean if your car battery light stays on even after you replaced it?
means your battery isn't being charged by the alternator. What originally seemed like a flat battery being the problem, would more than likely be the alternator at fault, which will drain the battery, not keep it charging on the move, hence, battery light displayed on your dash. Before jumping to the spares shop, check all the connecting wiring between these components, in case of any loose connections
Why would a fully charged battery and a new alternator drain the battery as the car is being driven?
Some possibilities: Cable is loose Alternator is faulty Some other electrical problem is causing an excessive drain. ---------------------- Also check the Fuse or Fusible Link. ----------------------- if new alternator: ck. mounting bolts for tightness & wiring. battery self maintenance? Alt. have intregal regulator? if not, should replace when replacing alt.
