SL-15 with User-Adjustable Flash Settings
1–2NM+ Solar Marine Light
Maintenance and Servicing
Designed to be maintenance free, the SL-15 requires minimal attention, though the following
maintenance and servicing information is provided to help ensure the life of your Sealite product.
1. Cleaning Solar Panels - occasional cleaning of the solar panels may be required. Using a cloth and
warm soapy water, wipe off any foreign matter before rinsing the panels with fresh water.
2. Battery Check - inspection of batteries should be performed every two years (minimum) to ensure
that the charger, battery and ancillary electronics are functioning correctly. Using a voltage meter,
check that the battery voltage is at least 3.6 volts under 50mA load, and ensure all terminals are
clear of foreign matter.
Replacing the battery
The SL-15 lantern is the only compact marine lantern with a double sealed battery compartment. This
provides the user with the ability to change the battery after years of operation.
1. Remove the 4 x battery cover screws and lift the cover and battery out of the compartment to expose
the adjustment plug.
2. Unscrew the adjustment plug.
3. Use a small flat bladed screwdriver to turn unit OFF.
4. Unscrew positive and negative battery leads.
5. Discard old battery in a safe manner. Please remember to recycle where possible.
6. Reattach positive and negative leads to new battery and then place back into case.
7. Switch lantern ‘ON’ via internal switch.
8. Cover the light, in darkness, for at least 30 seconds to activate the light sensor. Make sure the light is
flashing correctly.
9. Uncover the light and wait at least 30 seconds to make sure the light turns off in daylight.
10. Insert the adjustment plug and replace the battery.
11. Replace the cover and secure using the 4 x screws.
Care must be taken to observe the polarity of the battery before the leads are re-connected, and
ensure the replacement battery is correctly fitted. Always discard old batteries in a safe manner.
Long Term Storage Instructions (>4 weeks)
If light is required to be stored for longer than 4 weeks, please turn the light off using the internal
ON/OFF switch (and external ON/OFF switch where fitted).
1. Remove the 4 x battery cover screws and lift the cover and battery out of the compartment to expose
the adjustment plug.
2. Unscrew the adjustment plug.

If the INTERNAL switch is set to the ON position, the operation of the EXTERNAL switch is
bypassed and the lantern is ON.
