If the battery charger on your Evatac flashlight blinks from red to green repeatedly when you connect the batteries to the charger, it could indicate a problem with the batteries or the charger itself.
Here are a few possible reasons why the charger is blinking from red to green:
The batteries may be faulty or damaged. In this case, the charger may not be able to charge the batteries properly, causing it to blink from red to green.
The charger may be detecting a problem with the batteries, such as overcharging or overheating. In this case, the charger may be designed to stop charging and start blinking from red to green as a warning.
There could be an issue with the charger itself, such as a loose connection or a faulty circuit. In this case, the charger may not be able to properly charge the batteries, causing it to blink from red to green repeatedly.
It is recommended to check the batteries and charger for any visible signs of damage or wear, such as corroded or dirty connections. If the issue persists, it may be best to contact the manufacturer or a qualified technician for further assistance.
