SL-C500 & SL-C600
Solar Marine Lanterns
Designed to be virtually maintenance-free, the SL-C500 and SL-C600 require minimal attention,
though the following maintenance and servicing information is provided to help ensure the life of your
Sealite product.
1. Cleaning Lens- occasional cleaning of the light lens may be required. Using a cloth and warm
soapy water, wipe off any foreign matter before rinsing the lens with fresh water.
2. 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.
3. Battery Check- inspection of batteries should be performed every three 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 12 volts under 100MA load, and ensure all terminals are
clear of foreign matter (SL125-C models only).
Replacing the Battery
The SL-C500 & SL-C600 lanterns have a sealed battery compartment which provides the user
with the ability to change the battery after years of operation. The 2-piece design ensures ease of
maintenance, as the base remains fixed to the supporting structure.
1. From the front of the lantern, unscrew the four socket cap screws from the base of the lantern, and
remove the body from the base plate.
2. Unscrew the 4 retaining knobs and remove the battery box lid.
3. Disconnect the positive and negative wires from the battery.
4. Discard old battery in a safe manner.
5. Reattach positive and negative wires to the new battery.
6. Replace the battery box lid, refit the 4 retaining knobs and tighten securely.
7. Replace the lantern body onto the base plate ensuring that no wiring is protruding, and screw four
socket cap screws firmly.
8. To test place dark cover on top of light to activate sensor, light will come on.
Care must be taken to observe the polarity of each wire before they are connected.
To ensure waterproofing of the unit, make sure that no wires are protruding and that there is an
even seal.
Always discard old batteries in a safe manner.
