Batteries - Heavy Duty

About

Heavy‑duty batteries are low‑cost, single‑use cells typically made with zinc‑carbon or zinc‑chloride chemistry. These are ideal for devices with low to moderate power demands where long-term performance is not critical. The chemistry behind heavy‑duty batteries usually delivers a nominal voltage of about 1.5V. While their energy density is lower than modern alkaline batteries, they remain a practical choice for everyday use in remotes, clocks, and flashlights that don’t demand high current. Heavy‑duty batteries are valued for their simplicity and affordability, making them a great fit when you need a reliable, inexpensive power source without needing a rechargeable option.
