We have substituded a Silver Oxide battery in it's place.Mercuric Oxide buttons were commonplace in cyclocomputers but, because of concerns about toxicity and environmental pollution, these cells are no longer manufactured. Silver Oxide cells produce 1.55V which is a little higher than the 1.35V produced by the original mercury cell. |
