Energizer 386-301 Watch Battery

Keep your precision timepieces and high-drain electronics running smoothly with the Energizer 386-301 Watch Battery. This high-performance silver oxide cell is a "multi-drain" battery, engineered to provide reliable power for both high-drain devices (like digital watches with backlights and alarms) and low-drain devices (like classic analog watches).

With its stable 1.55V output, this battery ensures consistent accuracy for timepieces, medical devices, and calculators. Like other Energizer specialty cells, it is designed with zero mercury and features a leak-resistant construction to protect your expensive electronics from internal corrosion.

Key Features

• Multi-Drain Performance: Optimized to handle the high energy pulses needed for digital functions while maintaining steady, long-term power for 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 delicate electronic components.
• Mercury-Free Formula: Responsibly designed with 0% mercury, making it a safer choice for both your home and the environment.
