The A14PX or PX14A is a mercury-free replacement for the once popular Mercuric Oxide PX14, EPX14, or Nedo 1201 cell that was commonly used in cameras. Mercury cells are now banned because of toxicity and environmental concerns. The A14PX or PX14A cells produce 3.0 Volts, which is higher than the 2.7 Volt produced by the original mercury cell. Most devices accommodate the small increase in voltage and function perfectly.
