Alkaline Manganese Dioxide Battery 1.5Volt LR20 battery D size battery

Alkaline D Cell LR20 Battery is a Maximum Power battery for High-Demand Devices battery

Lr20 Alkaline battery Extended Runtime for Power-Intensive Devices

Alkaline battery size D LR20 batteries deliver unmatched endurance for energy-hungry devices.

With a massive typical capacity of 12,000–18,000 mAh, they provide up to 10× longer runtime versus zinc-carbon equivalents.

This powerhouse performance ensures months of continuous operation in heavy-drain equipment like boomboxes, industrial lanterns, and high-torque toys.

The low self-discharge rate (≤2% annually) guarantees reliable emergency backup power for years.

Ideal for devices requiring sustained energy, LR20 batteries drastically reduce replacement frequency and maintenance costs.
