The S23PX is a mercury-free replacement for the once popular Mercuric Oxide PX23 (or V23PX) battery cell that was commonly used in cameras, the Retina S2 Flash and Sennheiser microphones such as the Sennheiser K3U. Mercury cells are now banned because of toxicity and environmental fears.
The silver oxide S23PX replacement for the PX23 produces 6.0 Volts, which is higher than the 5.6V produced by the original mercury PX23 cell. Most devices accommodate the small increase in voltage and function perfectly.
The S23PX, with its long battery life and rock-steady voltage,
is likely to be your ideal replacement for the PX23. Consider buying more than one. These Silver
Oxide cells have a very long shelf life, so buy two and make sure you always
have a ready supply of power for your device whilst taking advantage of our
reduced price multi-buy offer.
