Panasonic AA Heavy Duty batteries are Zinc-Carbon batteries primarily used in low-drain devices such as remote controls, clocks, flashlights, and basic electronics. They are also known by alternative names such as R6P, 15D, and UM-3. These batteries are equivalent in size and voltage to AA Alkaline batteries. However, the AA Alkaline batteries are Alkaline-Manganese batteries with a significantly longer charge capacity, though at a higher price point.
Panasonic AA Heavy Duty batteries operate with a standard voltage of 1.5 volts and have a termination voltage of 0.9 volts. Their capacity is approximately 400mAh (though it may vary depending on usage), and they measure 14.5mm x 50.5mm.
These batteries function effectively in a temperature range of -20°C to +50°C, though they should be stored at temperatures below 30°C. The chemical composition of Panasonic AA Heavy Duty is Zinc-Carbon (ZnC).
