Eveready Battery Co 357BPZ-3N 1.5V Watch Battery 3 Pack

Product Description

The EVEREADY BATTERY CO 357BPZ-3N is a 1.5-volt silver oxide button cell battery sold in a 3-pack, designed for low-drain precision devices such as watches and calculators. Silver oxide chemistry delivers a stable voltage output across the discharge cycle, which is critical for accurate timekeeping and consistent calculator display performance. Each cell is a direct functional equivalent to the Duracell D303-357b, making this pack a straightforward replacement when servicing or restocking devices that specify that chemistry and form factor. The 357BPZ-3N is handled by watch repair technicians, jewelers, and electronics service shops.

This battery is used in quartz analog and digital wristwatches, pocket calculators, small medical devices, and other compact electronics that require a stable low-drain power source. The button cell format fits standard 357-size battery compartments found across a wide range of consumer and professional devices. The 3-pack quantity suits service counters and technicians who replace watch batteries in volume rather than one-off retail scenarios.

Key Features

• 1.5-volt silver oxide chemistry for stable, flat discharge voltage
• 3-pack format reduces per-cell cost for service professionals
• Compatible replacement for Duracell D303-357b cells
• Designed for low-drain devices including watches and calculators

Compatibility

Comparable to Duracell D303-357b. Designed as a direct replacement for 357-size silver oxide button cells used in quartz watches, pocket calculators, and similar low-drain precision electronics.

Installation Notes

Battery replacement in watches is typically performed by a watch technician or jeweler using a case-back opener and non-magnetic tweezers. Observe correct polarity when seating the cell, and avoid touching the cell surface with bare fingers, as skin oils can affect contact quality. Reseal the watch case back fully to maintain any dust or moisture resistance the housing provides.
