Panasonic Heavy Duty Batteries AAA Card 4 Pieces Each Card

Panasonic AAA Heavy Duty batteries are Zinc-Carbon batteries commonly used in low-drain devices such as remote controls, clocks, flashlights, and small electronics. They are also known as R03, 24D, UM-4, or Micro batteries. While they share the same size and voltage (1.5 volts) as AAA Alkaline batteries, the latter, made of Alkaline-Manganese, provide a significantly greater charge capacity but come at a higher cost.

These batteries operate at a standard voltage of 1.5 volts with a termination voltage of 0.9 volts. They have an approximate capacity of 400mAh, depending on usage conditions, and their dimensions are 10.5mm in diameter and 44.5mm in length.

Panasonic AAA Heavy Duty batteries perform well in temperatures ranging from -20°C to +50°C, though they should be stored at temperatures below 30°C to ensure optimal longevity. Their chemical composition is Zinc-Carbon (ZnC).
