16 accord EXL. Replaced battery and all of a sudden I have a light show on my dash random lights flickering .It was just happening going up hill ,But not all the time .any suggestions? Thanks

 

Check the battery hold down is properly installed and preventing the battery from moving. Check battery terminal connections, the connector to the battery sensor, etc.

 

Sorry I should have given a little more history .We bought the car seven months ago 38,000 miles mint cond, A few months in ,Random lights started flashing on the dash and it wouldn't start, I jump it ,Get it home and charge the battery that had two years on it's warranty. I know that does not mean it was good hindsight I should have tested it . I turned it in for core charge. New battery installed secured , All terminals clean and tight all good . Car starts runs fine for a little while then lights started randomly flashing on the dash mostly going up hill ..now it's getting worse not just going up hill anymore. Apparently from what research I've found it seems to kind of a common problem . flashing light's car's won't start leaving folks stranded. People saying their changing out starters ,alternators and lot's of batteries.. I was wondering if anyone here had any insight on the problem.. Before I throw in the towel and take it somewhere .Thanks
