The EVEREADY BATTERY CO 379BPZ is a 1.5-volt silver oxide button cell battery designed for low-drain, precision devices such as watches and calculators. Sold in a 6-pack, each cell delivers stable, long-lasting voltage output suited to the continuous low-current draw typical of analog and digital timepieces. At approximately 0.02 pounds per unit, the cells are lightweight and compact, making storage and inventory management straightforward for service counters and repair benches alike. This battery is a direct comparable replacement for the Duracell D379b, giving technicians and service pros a practical alternative when stocking button cell inventory.
The 379BPZ is used in residential and commercial watch repair, calculator servicing, and any small precision electronics application requiring a standard SR521SW-size 1.5-volt silver oxide cell. Typical install scenarios include watch battery replacement at jewelry counters, electronics repair shops, and field service kits where reliable long shelf-life cells are needed. The 6-pack format suits service professionals who replace multiple batteries per service call or want to maintain bench stock without frequent reordering.
Comparable to Duracell D379b. Designed as an OEM-style replacement button cell for watches, calculators, and similar small precision electronic devices requiring a 1.5-volt silver oxide battery.
Button cell replacement is typically performed by watch repair technicians or electronics service pros using a case-opening tool appropriate for the device being serviced. Always verify polarity orientation before seating the new cell. Dispose of used button cells in accordance with local battery recycling regulations, as silver oxide cells are not suitable for standard household waste disposal. Keep cells away from children during handling and installation.
