Energizer 395-399 Watch Battery

Keep your precision timepieces and small electronics running at peak performance with the Energizer 395-399 Watch Battery. This high-quality silver oxide cell is a "multi-drain" battery, meaning it is uniquely engineered to provide reliable power for both high-drain devices (like digital watches with lights and alarms) and low-drain devices (like classic analog watches).

With its stable 1.55V output, this battery ensures consistent accuracy for quartz movements, calculators, and medical devices. Like all Energizer specialty cells, it is manufactured with zero mercury and features a leak-resistant design to protect your delicate internal components.

Key Features

• Multi-Drain Performance: Optimized to handle the high energy pulses needed for digital displays while maintaining the steady, long-term power required by analog movements.
• Stable 1.55V Output: Delivers a flat operating voltage, which is crucial for the precision of quartz watches and medical monitors like glucose meters.
  
• Leak-Resistant Technology: Engineered to prevent internal leakage that can corrode and damage expensive electronic circuits.
• Mercury-Free Formula: Responsibly designed with 0% mercury, making it a safer choice for your home and the environment.
