I got a new battery in the summer of 2016. But yesterday my check gauges light lit up and my batter gauge dropped to 9 after I turned it on. Today, upon turning it on the gauge goes to the notch between 14 and 9 but falls to 9 after driving around 10-15 seconds. I'm not sure what is wrong and how to correct it. I'm trying to learn but if it's something that only a mechanic can fix I'm okay with that. Thank you for you're help and I look forward to you're answer about what is wrong and you're suggestions
