Applies to all Sea Dragon lights with 1200+ lumens and Fluoro-Dual Beam models.
Clean the gold-plated contacts on battery and inside battery compartment EVERY TIME before charging the battery. Use a clean cotton cloth moistened with isopropyl alcohol to thoroughly clean contacts. Not cleaning the contacts will permanently damage the gold plating and result in the device not powering on.
DO NOT store the device with battery installed. Remove battery before storage.
Left contact shows black spots resulting from not cleaning the contacts.
If the Sea Dragon light does not power on, do this:
When the Sea Dragon 25Wh battery (SL9831) is fully charged, the charging status light turns from red to green. It takes about 3 hours to fully charge the Sea Dragon battery. If the status light does not turn green, clean the gold-plated contacts on the charging tray and battery using a cotton swab moistened with isopropyl alcohol battery. Also make sure that the battery is fully seated into the charging tray. If this does not resolve the issue, contact the SeaLife Service Center in your country to have the charger and charging tray replaced.
The Sea Dragon 1200, 2000, 2300, and 4500 Auto Lights include an “Auto Flash Detect” feature that uses a flash sensor to turn off the light for 1 second if it detects an external flash firing. This feature helps reduce backscatter. If you quickly swipe your hand (or some other object) in front of the light, the light sensor may mistake the object as a flash and accidentally turn of the light for 1 second. If you keep the object held directly in front of the light or in low visibility water, the light may continuously turn off and on, similar to a strobe light effect. If this occurs in low visibility water, we recommend disabling the auto flash detect feature.
To turn off Auto Flash Detect mode:
Note: For Sea Dragon 2300 Auto light (SL674), the Auto Flash Detect feature only works in 100%, 50% and 25% brightness settings and not in Auto Brightness setting. The Sea Dragon 4500 Flash Detect works in all modes.
