At first we thought we had a bad batch of batteries. So we switch out batteries with our long standing working gauges. The good gauges worked well with the batteries and the bad ones didn't. Also, these issues are intermittent. Sometimes if you open and close the battery "drawer" a few times it will work for a good while. That might be why the battery looks like it has been around the block a few times. I think it might have to be an issue with the connection. When we received this repaired gauge. We switched out batteries and it still read "Low battery" as in the photo I sent. I think they really need to take a deeper dive into the issue.
