Check your alternater. Sounds like it is bad in which case you are running just on the power from your battery which won't last long.

What is causing the Diodes in the Alternator of a '93 Topaz to keep burning out and draining the battery of it's charge while sitting?
most of the time the diode circuit will burn out trying to keep a defective battery charged, which results in overheating or increased amperage for the charging circuit which includes the diodes.
Why is the battery in car dead after sitting over the weekend?
Something must be draining the battery while it is not running. Usually it is caused by an interior light being left on either inside or perhaps the trunk or one of the doors were not closed completely and thus causing the interior lights to stay on and drain the battery. Otherwise, this will continue and you should plan on replacing the alternater and/or battery
Why are your lights dim on your 1990 Nissan nx?
Depending on how dim, it could be your battery, alternator, or poor power supply at the headlight socket. Poor power supply meaning corroded wires causing high voltage drop. Have the battery and alternator tested and go from there.
What could be wrong if the battery is good and the alternator is good but the battery keeps being drained?
Something is causing a drain on the battery even with the vehicle off and nothing turned on. A good mechanic can do a drain test on the battery to see what may be draining the charge. A dead cell in the battery itself will also cause the battery to go dead. Disconnect the negative battery cable overnight and if the battery is dead the next morning it has a dead cell and must be replaced. If not look for a light that is on or a relay that is stuck.

Is it worth charging a car battery if it has gone flat several times?
If you don't keep an otherwise good battery charged in freezing weather it can freeze and break the case. If your battery won't hold a charge because something is draining it, you should disconnect a cable and charge it then reconnect it before you try to start the car...or fix whatever it is that is causing the draw. It is better to keep the battery charged so you can start the car when needed. Consider hooking a battery tender to the battery if it discharges because of long-term disuse.
Why is Battery discharging mustang 1971?
First have the battery checked, then perform a test where you observe a volt meter while you disconnect different systems in the vehicle, when you have stopped the drain you have found what is draining the battery. I would look first to the wiring harness where the alternator wires merge into it, i had a problem with mine and some melted insulation causing massive problems with the electronics. the alternator is always a good place to look.
My car died while driving last night so i replaced the battery. AutoZone tested the alternator and said it was working but it was draining my battery slightly...what could be causing this?
Don't believe a word AutoZone tells you. My battery died so I went there and they tested my battery and alternator and told me it was the battery. So I bought a new battery and 2 days later, dead again. Went back and they tested again and THIS time, it was the alternator. I went nuts on them and ended up getting both my battery AND alternator for free for their mistake that left me stranded at 12am.
