When we changed the batteries, we lost the bottom of the batteries connections + attached springs. Can this part be replaced?
JONATHAN B You can order that piece from the Underwater Kinetics website. In a search engine, search Underwater Kinetics c4 xenon, click on the link that goes to the UK website. Towards the bottom of the page there is a tab that says parts, click that and the part you are looking for is Alkaline Battery Contact Plates, C4R/C8R/Light Cannon eLED, it runs $18.99. I am pretty sure that is the part you are looking for.
