Why Choose ML1220 Over Alkaline or NiMH Batteries?
Unlike alkaline batteries, the ML1220 operates reliably in extreme temperatures and delivers consistent voltage until depletion. Compared to NiMH rechargeables, it offers 5x lower self-discharge, eliminating frequent replacements. A 2022 study showed ML1220-powered IoT sensors lasted 37% longer than alternatives in sub-zero environments.
The ML1220’s unique chemistry enables operation in environments where traditional batteries fail. In industrial freezer monitoring systems (-30°C), these batteries maintain 95% capacity after 5 years versus alkaline’s 40% capacity loss within 18 months. For applications requiring continuous voltage output, such as precision gas detectors, the ML1220’s flat discharge curve prevents false low-battery alerts common with NiMH cells.
