Perhaps alternator is not charging battery sufficiently, test with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be approx. 13.8-14.2volts

Why does your battery gauge keep dropping to zero on your 2003 Monte Carlo after you have just replaced the battery?
Bad alternator not charging battery? Bad voltage regulator? Blown fusable link?
Why is the voltage of the NiMh decrease on battery cell?
All cells drop in voltage as they lose their charge. Often old cells do not attain full voltage even at their maximum charge. It's just the way the chemistry works. Electronic systems that require constant voltage have regulation circuits that step the voltage up to the necessary level and keep it constant, even though the battery voltage may be dropping.
How does an alternator keep a cars battery charged?
An alternator has diodes which transform ac voltage to dc voltage so that the battery gets negative and positive current on its poles thus making the battery to be charged.
Will a bad voltage regulator keep a 1995 sebring from starting up with a new car battery?
No, not if the battery is fully charged.
Will a car keep running if the battery is removed?
Usually yes if alternator is good not a good idea alternator can burn out all your components without the battery to keep the voltage down
How many hours does a lawn mower battery have to be on a float charger?
A battery float charger is intended only to keep a fully charged battery from losing its charge. It will NOT work to charge a battery that is discharged or damaged. Check the voltage of the battery to be charged. Do not use charger if the battery voltage is less than 9.6 volts.
When you add a second battery to a series circuit what happens?
Adding a seound battery to a series circuit will increase the voltage, and require less current to keep the lights (if there are any on) as bright. Say you have a 6v battery, then you add another 6v battery. the voltage of the circuit would be 12v
Would a car stall if the battery was dead?
The problem is probably the alternator. If the alternator fails to keep the battery charged the battery will keep the car running until it can no longer supply voltage to essential systems and the car will stall.
Why does the indicator keep flashing?
Which Indicator?
Why does the battery light come on when you accelerate?
The alternator may not be able to keep up to the voltage requirement of the vehicle check voltage output of alternator w/mechanical gauge
What is the voltage output for the alternator on a 2002 Kia Spectra?
It has to be 13 plus volts to keep the battery charged. The car requires a 12 volt battery to start and run this vehicle, so you need more then 12 volts to keep the battery charged.
What would dodge durango keep going dead and have too high of a voltage when put on a tester replaced the battery still drawing to high of voltage and battery dead?
With the engine running you should read 13.5 to 15.5 Volts DC at the battery posts. A reading much higher than this indicates the voltage regulator in the alternator is defective.
