I'm not too good with electronics but I had an issue today which I believe signals that my 3 year old battery needs to be replaced.
I was sitting in the local bus station parking lot waiting for a friend. I had the GPS still on and plugged in, my phone charging and the key turned to ACC while listening to music. Next thing I know the a dinging comes from the speakers and the dash display informs me that there was a charging system failure. Having had the same issue happen once after forgetting to unplug my OBD II bluetooth unit I was pretty sure the battery just needed a jump, so I managed to find someone with a jumpbox and got it started again.
However in the last hour after leaving my friends house I noticed that my coolant gauge didn't move off of cold over the course of the 15 minute drive and the rpms at 55mph were bouncing between 1500-2000 rpm every 10-15 seconds. When I noticed this I turned down the radio and listened for fluctuation in engine speed since I didn't notice a power surge and there was none. Then I turned on the heater and it worked just fine.
I'm assuming this just means my battery has a cell thats going bad?
