Installation Instructions

    1. First remove the black soft plastic end cover that is glued to the battery pod.
    2. Very carefully insert a straightened out heavy paper clip that has been bent in half between the cover and the battery pod, moving it around to break the glue’s bond without tearing the cover.
    3. Once the cover is free, remove the cover from the pod.
    4. Mark the end cap and battery pod with a magic marker so the end cap can be replaced in the same position.
    5. Completely remove both set screws holding the end cap in the battery pod.
    6. Very carefully twist and pull the end cap out of the tube, the resistance is from the O-ring which must NOT be damaged or the pod can leak.
    7. The battery pack will now slide out of the pod, make sure there is no dirt or sand left inside the pod by wiping it clean.
    8. Disconnect the old battery pack.
    9. Very carefully remove and clean the O-ring, do NOT use any sharp instruments to remove it.
    10. Once the O-ring has been wiped clean with a soft paper towel apply silicone grease all around the O-ring sparingly, Ace Hardware 90% pure silicone grease 4095667 works well as does Sil-Glyde.
    11. Place the O-ring back into the end cap groove and connect the new battery pack, making sure the connectors are clean, optionally add some dielectric grease.
    12. Slide the new battery pack into the battery pod, if it is a tight fit due to the older pod versions taper, apply some silicone grease to the edges of the pack to insert.
    13. If a silica desiccant pack came out of the pod when opened replace it at this time.
    14. Very carefully twist and push the end cap back into the pod without pinching the O-ring, which could cause leakage.
    15. Once the end cap is back in and the magic marker lines and screw holes line up, place the set screws back in.
    16. Do NOT over tighten, snug them down firmly without stripping the threads.
    17. Place the soft black plastic end cover back on by putting two dabs of RTV silicone rubber inside it and pushing it on.
    18. Optionally you may wrap a turn and a half of electrical vinyl tape around the battery pod covering the set screw holes and let friction hold the end cover in place.
    19. Charge the new battery before use.
    20. ONLY use the supplied charger for charging the Lithium Polymer Battery
