Arlec Alkaline Extra Heavy Duty Battery - BE-4AA

The Alkaline Extra Heavy Duty Battery – BE‑4AA is a pack of four zinc‑chloride ("extra heavy-duty") AA cells designed for low‑drain devices like remotes and clocks, offering roughly 1,000–1,500 mAh capacity per cell—approximately twice the life of basic carbon-zinc batteries but significantly less than alkaline cells. While more affordable upfront, BE‑4AA batteries underperform compared to alkaline in high-drain or long-term use, delivering shorter shelf life (2–3 years vs. 7–10 years) and dropping voltage faster under load.
