So my battery light/warning just came on. Volt meter is between 8 and 12. Questions -

Is this most likely a dying battery, or is it the alternator? Shouldn't the alternator be charging the battery while I'm driving? Since my battery is losing power while I'm driving, I'm concerned that it may more likely be the alternator that failed. How do diagnose this properly without wasting $$?

If it is an OE battery and over 3-4 years old it should be replaced anyway.

So a new battery wouldn't really be a waste of money. If it solves your problem then great, otherwise the alternator or charging circuit are somehow bad and it should just me taken to a mechanic.

Another option would be to borrow someones know working good battery.
