Replacing the Batter in Your LightCap 300
- 1. You will need a #10 torx driver to remove the screws from the cap.
- 2. Remove the large O-ring that seals the cap to the bottle.
- 3. Remove the swivel retainer ring from the cap.
- 4. Remove the two (2) torx screws from the top of the cap.
- 5. Turn the cap over and slowly pry the inner cap from the polycarbonate outer cap using a butter knife or similar blunt blade
- 6. Remove the inner cap.
- 7. Note the three black O-rings and be careful not to lose them! The smaller ones may still be in the outer cap when you remove the inner cap. Remove them and put them aside. [Note: if you lose a small O-ring or if they are broken, you can simply use a small dab of silicone caulking on the screw post when you reassemble the cap.]
- 8. Remove the two screws that attach the LED reflector to the cap.
- 9. Remove the reflector from the circuit board.
- 10. Carefully fold the circuit board back to reveal the battery.
- 11. Remove the battery, being careful not to break any of the wire connections.
- 12. If the battery simply falls out, the metal terminals on either end of the battery compartment may need to be bent slightly so that they make a good connection with the new battery. Use a knife, small screwdriver or needle-nose pliers to bend the terminals in.
- 13. Insert the new rechargeable AA battery, again being careful not to disturb the wires. [Be sure the + and – ends are in the correct position]
- 14. Replace the circuit board (don’t pinch the wires!) and the reflector, lining up the screw holes.
- 15. Replace the two screws through the reflector and circuit board, into the cap.
- 16. Note that there is only one correct way to replace the inner cap to the outer one: there is a small stud on the inner cap that inserts into a hole in the outer cap.
- 17. Replace the inner cap, being sure that all three O- rings (one large and two small) remain in place.
- 18. Push the inner cap into the outer cap so that the small O-rings remain in place and the screw holes line up.
- 19. Replace the outer cap screws.
- 20. Replace the bottle seal O-ring.
- 21. Replace the swivel retainer.
