Duracell 303/357 SR44 Silver Oxide Button Battery 1.5V 3-pack

Product Description

The DURACELL 00041333661292 is a silver oxide button coin cell battery rated at 1.5 volts and 175 milliamp-hours (mAh), sold in a 3-pack. It is a disposable, single-cell battery sized to the 303/357 footprint, also referenced by IEC designation SR44. The flat terminal style and round form factor make it a straightforward drop-in for compact, low-drain electronic devices. At 0.455 inches in diameter and 0.22 inches in height, it fits tight battery compartments found in precision instruments and small consumer electronics. Licensed HVAC techs, medical equipment service pros, and electronics technicians keep these on hand for servicing devices that require a stable, long-lasting low-drain power source.

This battery is suited for low-drain applications across residential and light commercial environments. Typical end uses include calculators, medical devices, toys, and watches. The 303/357 size is one of the most common button cell formats in the field, so a 3-pack is a practical quantity for service vans or shop stock. The silver oxide chemistry delivers a flat discharge curve, meaning the voltage stays consistent through most of the battery life before dropping off sharply at end of service.

Installation Notes

Button cell replacement is typically performed by the end user or a service technician using a small flathead screwdriver or coin to open the battery compartment. Always power down or switch off the device before replacing the battery. Observe polarity markings inside the compartment before seating the new cell. Dispose of used silver oxide batteries in accordance with local regulations, as they contain silver and should not be placed in general waste.
