Type: Silver Oxide Voltage: 6V. Diameter: 13mm Height: 25mm Also known as: 4SR44, V28PX, PX28, 544, KS28, RPX28, S1325S, S1325, PX28-S, 1406SOP, RFA1611, RFA-16-11.This 4SR4 or PX28-S battery is a popular silver oxide battery. Commonly used in cameras (such as the Minox 35ML, Bronica GS-1 and Canon AE-1), lightweight meters and blood sugar testers. This 4SR44 or PX28-S battery is a popular replacement for the now discontinued PX28 Mercury battery. These mercury batteries, no longer manufactured due to their toxicity, were variously known as PX28, 4MR44, V4034PX, 4H-C, 4NR44, HM-4C. 4SR44 or PX28S batteries have a lifespan of over 8 years, so why not buy two or more? This 4SR44 silver oxide cell has exactly the same dimensions as the alkaline LR44s, but has a longer battery life. You can always use this 4SR44 silver oxide battery instead of a 4LR44 alkaline for improved performance and less frequent battery changes.

was almost expecting there to be erosion or something else due to how cheap it was. fortunately, there was nothing to worry about and it works just fine.

I only needed one or two and I received like six or more of these batteries, so they're probably just gonna get old up in a shelf. Bummer.

these batteries are virtually unobtainable in Australia. Vinnic was able to supply them at reasonable cost within the specified time. All very efficient
