Battery drained twice in three days. Heard clicking noises by the passenger side

Appreciate it. I can't imagine why the dealership didnt' notice this when I took it in Monday for service regarding a battery issue...

I just went to start this morning. Its still charging. Sitting at 10V right now, can't start it up. So waiting for it to fully charge still.

If you have the charger connected to the battery post connectors, that sounds like a bad battery or bad connections at the posts. Clean the posts and connectors (you can find a tool at most auto part stores that has male and female brushes of the proper size). A very thin coat of bulb grease on the mating surfaces will lessen corrosion in the future.

Alright, I'll go and get brushes at autozone to clean it up once I can start
Nissan on Monday said the battery and cells tested just fine (ugh, its a 4 yr old battery now). Should I just go buy a new battery from autozone at this point? Or go to the dealership and buy a battery there

I'd check the electrical connections and verify that the alternator is putting out correct voltage first, but, yeah, it's quite possible that the battery is bad.

I've heard of cases where a battery would pass the test but still not function properly in the car.

You should be able to get a battery at an auto parts store cheaper than what a dealership will sell you one. Same for most other parts.

Time for a new battery. Factory batteries at that age are just waiting for a good excuse to quit. I put an Optima RedTop in mine not to long ago, then stuck a tender on overnight.

Good news. Let the car charge some more, and it wouldn't' go past 10-11V. (Obviously battery is dead at this point then). Get the car jumped, drive over to Autozone. We disconnect everything, and test the battery. Reads bad. So now we know the big culprit! Also funny thing. On red tag for the positive connection is a warning label about windows and other items not properly initializing due to bad battery or low volt.

Anyway we remove the old battery and go to install a new one. I was planning on an Optima... they literally only had one battery, a duralast in stock for my car, the ****? Ah well... we installed the battery, cleaned the connections and everything is good now. In the future I'll order an optima Redtop online and be done with it. FYI the guy told me that batteries in FL only last around 44Months typically. Good thing to know.

Thanks everyone for the help! Fingers crossed no other issues arise.

Glad to hear you found the problem and that it was an easy fix.

A few things to keep in mind after removing power from the car: windows may need to be reset, radio presets will probably need to be reset, engine may run rough for a while as the ECM re-learns the engine, you won't pass an emissions check until you've gone through several drive cycles.

PS: I wouldn't go to the trouble/expense of getting another battery. But that's just me. YMMV
