FAQ for Smart Smoke & CO Detector Batteries
A: This is achieved through a specialized, non-rechargeable (primary) lithium chemistry (often Li-MnO2, though advanced LiPo is an option for some smart features) with an extremely low self-discharge rate, typically less than 1% per year. The entire device, including our battery, is designed for ultra-low power consumption.
A: No. To comply with modern safety standards and ensure a decade of protection, these batteries are designed to be permanently sealed inside the detector. The entire unit is replaced after 10 years.
A: Due to the life-safety critical nature and high-volume production of these devices, our MOQ for a new custom design typically starts at 50,000 to 100,000 units.
A: Yes, absolutely. We design the battery with a very low internal resistance, enabling it to deliver the high, instantaneous power pulse needed to drive a loud piezoelectric or electromagnetic siren, even after nearly 10 years in standby.
A: It differs significantly. It’s a primary (non-rechargeable) cell optimized for minimal self-discharge, not for charge cycles. The chemistry, separator, and electrolyte are all engineered for maximum stability and longevity over high capacity or high discharge rates.
A: Yes, the battery is designed to power the low-power radio (like Zigbee or Wi-Fi) for both regular check-ins and emergency signal transmission to other alarms in the network.
A: After the design is finalized, the lead time for the first batch of prototypes for this specialized chemistry is generally 6-8 weeks.
A: We provide a comprehensive battery data package, including specifications, material data, long-term discharge modeling, and all necessary safety test reports (like UN38.3) to support your end-product’s submission to UL or other certification bodies.
A: Our batteries are designed with multiple safety features, including thermal vents. They are rigorously tested to withstand high temperatures as required by safety standards, ensuring they can power the alarm during the critical moments of a fire event without becoming a hazard themselves.
A: Please provide the target dimensions, required service life (e.g., 10 years), the power consumption profile of your device (standby, test, and alarm currents), and your estimated annual volume.
