FAQ for Smart Thermostat & Sensor Batteries
A: This is achieved through a holistic approach: an ultra-low self-discharge cell chemistry, a protection circuit with near-zero quiescent current, and working with your team to ensure your device’s firmware is highly optimized for deep sleep modes.
A: It depends on the application. For thermostats that have access to power wires (C-wire) for charging, a rechargeable LiPo is ideal as a backup. For remote sensors, a high-density primary cell might be an option, but our rechargeable LiPo solutions offer sleeker form factors and the marketing benefit of being “rechargeable.”
A: For a new custom design, our MOQ typically starts at 50,000 to 100,000] units, reflecting the needs of high-volume smart home products.
A: We design the cell’s internal structure to have a low internal resistance (ESR), which allows it to deliver the high, short bursts of current needed for data transmission without a significant voltage drop, even after years in a low-power state.
A: Absolutely. Safety is a primary design driver. Our batteries are rigorously tested to meet and exceed the highest international safety standards for in-home consumer electronics, such as UL and IEC 62133.
A: Our low self-discharge batteries have an exceptional shelf life, retaining the majority of their charge for many years in storage. This is critical for products that may sit in a retail channel before being sold.
A: After the design is finalized, the lead time for the first batch of prototypes is generally 4-6 weeks.
A: Yes, this is a core strength. We excel at creating custom-shaped, ultra-thin batteries that allow your industrial designers to prioritize aesthetics.
A: Yes, we can provide the battery with pre-soldered wires and a wide variety of standard or custom micro-connectors to simplify your manufacturing process.
A: Please provide the target dimensions, required battery life (in years) and/or capacity (mAh), voltage (3.7V), details about your device’s power consumption (average sleep current and peak transmission current), and your estimated annual volume.
