Arlec Alkaline Extra Heavy Duty Battery - BE-2D

The Alkaline Extra Heavy Duty Battery – BE‑2D is a pair of D-size zinc–chloride ("extra heavy-duty") cells designed for extended life — typically offering 1,000–1,500 mAh per cell — to power moderate-drain devices like lanterns, radios, and large flashlights. While they outperform basic carbon-zinc batteries, they still fall short of true alkaline D cells, which offer significantly higher capacity and longer-lasting voltage.
