Observations of a dying or bad battery in hopes it may help others; For reference, I have a 2014 JKUWW. I have upgraded the Radio, Speaker, Speaker Wiring, and Factory Amp(s). I noticed a frequent random humming through my radio over the last couple months. Sound like a poor ground issue. I pulled the radio a couple times, checked the wiring and reseated connectors in an effort to find the issue. Just when I thought the humming was fixed it (not finding a direct cause) it would return on my next drive. Last weekend I loaded up Olive (my jeep) for a weekend of trails and camping. When it was time to leave, the starter was struggling to turn over as quickly as normal. Over the weekend Olive struggled but started up every time over the trip. After returning home I charged Olive’s battery overnight to make sure I did not have anything leaching power thus causing the stuttering. I was now suspect of the battery’s condition and just wanted to confirm. Monday night I went to pick up my daughter and notice a couple dash lights would flash, the led dome light was flickering when the door was open, and the radio was humming intermittently. At this point I was confident my original factory battery was at the very end of its useful life. I park the Olive in the garage, finished running errands and then picked up a new EverStart Platinum AGM Battery, Group H6 from Walmart for $150.00. Even though Walmart's website says it will not, this battery is a perfect fit. 760 CCA just in time for MN winter cold. It has been four days now and I have please that my Radio is no longer humming. I knew that a bad battery can cause dash lights to light up. I was surprised that the dying battery was causing issues with my audio system over the last couple months.
