The S28PX battery is a popular replacement for the now discontinued PX28 mercury battery. These mercury batteries are no longer manufactured because of their toxicity.

This Silver Oxide cell has exactly the same dimensions as the alkaline 4LR44s, but has a longer battery life. The 4SR44 is a long life silver oxide chemistry with non-declining power output; alkaline batteries of the same voltage start at 6 volts and at the half life are at 3 volts, silver oxide start at 6 volts and maintain the voltage until expiring. This is why silver oxide batteries are always used in legacy cameras, insulin pumps and sniper scopes or mission critical situations. Never use alkaline batteries for any device requiring a steady constant voltage.  You can always use this silver oxide 4SR44 battery in place of an alkaline 4LR44 for improved performance and less frequent battery changes.
