Standalone Smoke Alarm

0% Lead Zinc Chloride Battery Lead-free and environment friendly  In 1985, we began the mass production of zinc chloride batteries. Our monthly output reached 1.5 million units within five years and then increased to 10 million units. In 1993, we launched the first fully automatic zinc chloride battery production line, and tripled the production efficiency. Since 2004, Vinnic formulated pioneering 0% Lead Zinc Chloride Battery by using first-rank material. While the safety standard for lead is 40 ppm，this content in Vinnic’s Zinc Chloride Battery is much lower than the standard. This is a further milestone in the development of high performance, reliable and environment friendly batteries. Quality: Environmentally friendly Highest leakage resistance Low internal resistance Long Service Life Top performance Complete line of D, C , AA, AAA, N and 9 Volt  Application: • Alarm clocks • Radios -Remote Controls • Smoke detectors • Toys
