I was having problems starting the SUV (1993 Nissan Pathfinder) with an old battery. So I replaced the battery with a used, but fully charged battery (checked with a voltmeter). With this battery, the car was fully functional for a day of driving and turning on/off. The next day, the battery was completely discharged--no clock, no nothing--and the voltmeter reading was 0.4--dead.
So I jump started the car. Immediately afterwards it died when I put the car on drive (I wanted to move it). I jump started the car a 2nd time, left everything alone, and let it run for an hour. I came back afterwards, and opening the door turned off the engine. I checked the battery and it managed to charge to about 2 on the voltmeter.
What is going on?! I appreciate your help in advance--and happy holidays!

try the regulator ...it can overcharge and give the same result as undercharge....I had a car that did this was running at 18 instead of 15....so every time I got into it I had to clutch it.....or possibly the coil

Your alternator is faulty. The engine doesn't take as much battery current once it's started so even with a low battery it will run awhile even if the battery isn't being charged by the alternator. But eventually the battery charge will drop off to the point of not having enough power to run the engine or if any other electrical device is operated - like the dome light from opening the door - engine will die.

Could be a fault with the battery or something draining the battery. Connect an ammeter between the positive lug on the battery and the cable and see if it is drawing current.
I had a similar fault on a VW Golf that was eventually traced to a badly disconnected phone installation that the guy I bought the car off of had had removed.
Hope this helps.

Not sure but sounds like the alternator, do you have a voltmeter on the dashboard or an alternator light, if the light is on then it is not charging properly, and if you have a volt meter on the dash and it reads below 12 volts then it's the alternator, do you have a lot of kilometer es on the car? if so then it is probably the alternator. or, are there any loose wires somewhere.

I would be tempted to blame the alternator. once you get the vehicle running, take your voltmeter and check the alternator. Should read 13-14 volts

The truck runs after you jump start it so its not the alternator (you said it ran for over an hour after a jump start), you have another dud battery that cannot hold a charge. Get a new battery.

First I would check the charging volts from the alternator,but it also sounds like you have a short in your electrical system that could be draining the battery as it sits.You may need to take it to a good shop to find this short.Sometimes they can be hard to find on your on.I have had great experiences with AAMCO on Warren@Beaver Dam Rd.

Because the battery has no charge or is empty the battery will not re-charge after a jump start !

If that is have been given a splash of can charge in it you may pour boiling water onto it to get sufficient can charge to probable initiate it. If not pull it out, take it to your nearby storage and get them to place it on can charge for you.
