Battery bought in November of 2012

So I went to my car during lunch a few minutes ago to grab a bite to eat from somewhere and my car won't start but I think its more than just a dead battery.

I know what to expect from a dead battery but its doing more than that, the gauges are twitching and even after I remove the key from the ignition they keep twitching for about 10 more seconds. The voltage looks to be at 8-9 with the key turned to on so that's obviously an issue but what it with the guages?

So while I finish up my work day and let this weird dead battery issue sink more in my brain I figure I'd post here incase ya'll have seen it before.

Video I just recorded -
Thanks

 

The battery can go at any time. If you only have 8-9 volts then other than the Battery It could be the alternator may not be charging.
I have had this issue on several cars low voltage and the gauges are doing what yours are.
Your car has a draw all the time to keep the computer working. I might get the battery checked, and the alternator.
Good Luck

 

Ya I'll be getting a new battery tonight and crossing my fingers...the gauges are the part I didn't understand. I'm glad to hear you've seen them twitch like that though. I still fear something worse is going on - hope I'm wrong!

 

Your battery is 4 years old so.... ill bet its shot... ive seen that also.. the PCM doesn't have enough voltage to do the initial check before startup. I agree with drivernumber3 id have the alt checked as well just to be shure

 

Check pcm fuse. Should be a 10a. Mine did the same thing. Make sure battery cables aren't bare like mine were and welded themselves and blew the fuse

 

Turns out it was just the battery...The gauges are what got me, glad it was a quick one.
