2005 Acura TL. Battery & starter replaced. This morning it would not start, key fob not work. when key turned in ignition, nothing. No lights, radio, click. completely dead. What could the problem be?

Battery cables ? Hard to say for sure Cassandra ,Would need to do so electrical testing ! Do you own a DVOM - digital volt ohm meter ? There are videos on youtube showing how to do basic automotive electrical testing ! First one I would do is voltage drop testing the starting circuit , charging system ! Voltage Drop Test

2009 451 Passion. Why a frequent dead battery?

That is definitely wrong, not normal. Voltage should stay at 14 volts or near that until the battery is close to fully charged, then will slide down to about 13.5 volts, and stay there while engine is running. Also, a fully charged battery should show about 12.6 volts at a minimum, especially a new battery.
I don't know what is going on with your system. Take it back to Merc- were they aware of how it is acting, voltage-wise? Doesn't sound like it. One small possibility: is your alternator belt not tight enough?

Wasn't charging. changed battery and alternator. by the gauge it shows 14 volts but with the truck running and i unhook the battery it dies.

Not on new vehicles , you never ever pull a battery cable while it is running ! A voltage spike can take out electronic components ! That was 60's an maybe a few 70's vehicles ! That change when they started using transistors in voltage regulators an in engine modules. If it is show 14 volts it's charging ! I will send a link on how you test the charging system.

Clean battery connections, and/or check the battery to see if it retains a full charge. Fully charged batteries are normally holding a 13volt charge, and up to 14.5 volts will show on a gauge during charging

Alternator gauge shows discharge

Not sure I follow the story. The alternator is charging 100amps but the gauge shows less than 14 volts ? Is the alternator output at least 13.5 volts and is that getting to the battery ?

does your model have a/c as this can cause a problem if the clutch inside it is stuck. take the fan belt off and spin the comperser if it is hard to move that may be the problem.

Why did my pntiac vibe lose power while i was driving the radio turn off the gauges stop working and the engine lost power

The battery may only be 3 1/2 years old, but the factory
batteries seem to fail early in life

Check to see if has at least 12.5 volts across the terminals

I think you lost the battery & then the computer module went down,
as you turned into the driveway

If you only have 12.2 volts, don't try and charge it,replace it

If it does start ,check voltage again with engine running
The alternator has to output over 14 volts to charge a 12 volt

I think I have an alternator problem? The charge needle on the dash guage is spiking to 16 volts off and on. I put a voltmeter to the battery and it is only charged to about 11 volts. With the engine...

The normal charge of alternator on idling is about 13 to 14 volts. 12 is acceptable but keep in mind it will need attention soon. The needle fluctuates due to the revs of the alternator - there is nothing to worry about. Just look that the charge is always above 12V on idle.

Sounds like a bad alternator. Drained your battery and when you turned on the lights it took all the power left in your battery. When you drain a battery down that far, they are real hard to jump, and coupled with the alternator, the car is not producing enough current to start and stay running.

I would take the alternator off and take it to oyur local auto parts store to be tested. If bad, replace it and charge the battery fully before starting. Then check voltage at battery with motor running. Should be 13.2 -14 Volts DC. If not, you may have a bad battery cable or blown fusible link. (especially that if the alternator tests good).....Mike

Car wouldn't start replaced battery and it started right up. I didn't drive it until 2 days later started right up got to the store a few blocks away and it will not start, was told it was the starter so i...

probably the alternator, when you replaced the battery it had a full charge and once the vehicle used all that charge up and it wasn't charging it could no longer start the car anymore. If your battery light is on in the car it is a fairly certain sign that the alternator is not charging. Generally an AVR test is the best way to check the alternator, but if you can jump start the vehicle, connect a voltmeter to the battery it should be around 14 volts when the vehicle is running and around 12 volts when the vehicle is not running. If it is not at 14 volts when it is running, it is not charging.
