Eveready Battery Co 389BPZ 1.5V Silver Oxide Watch Battery

Product Description

The EVEREADY BATTERY CO 389BPZ is a 1.5-volt silver oxide battery designed for watches and small electronic devices. Silver oxide chemistry delivers stable voltage output throughout the battery's discharge cycle, which is critical for quartz watch movements and precision instruments that require consistent power. This battery ships in a 6-pack blister card and is a direct comparable replacement for the Duracell D389/390. It is primarily installed by watchmakers, jewelers, electronics repair technicians, and end users servicing their own timepieces or small electronic devices.

The 389BPZ is suited for residential and commercial applications wherever coin-cell silver oxide power is required. Typical use cases include wristwatches, pocket watches, small calculators, medical devices, and compact electronic instruments. The battery is sold in a 6-unit package, making it practical for service technicians who replace watch batteries as part of a recurring maintenance workflow. Its compatibility with the widely used 389/390 cell size means it fits a broad range of watch brands and electronic housings that accept that cell format.

Installation Notes

Battery replacement in watches and small electronics is typically performed by watchmakers, jewelers, or electronics repair technicians. Power the device down completely before opening the battery compartment, and use non-conductive tools when handling the cell to avoid short-circuiting. Dispose of used silver oxide batteries in accordance with local regulations, as they may contain materials subject to hazardous waste guidelines.
