What to do if my SPE HF2-UI Battery Charger is flashing red and yellow?
- TTiffany ThompsonAug 4, 2025
If your SPE Battery Charger is flashing red and yellow, it could be due to a poor connection. Ensure all connections are properly secured. Also, verify that the battery wasn't disconnected during the charging process. A flashing red and yellow light may also indicate a problem with the battery itself, so check the battery's condition and, if applicable, verify the water levels in lead-acid batteries.
