Overview
Smart home security and automation are evolving quickly. Devices like smart door/window sensors and smart curtain systems
improve safety, convenience, and real-time control in homes and commercial spaces.
To keep these devices online and responsive, the power source must be stable, compact, and long-lasting.
That is why lithium batteries are increasingly used in smart sensors and smart curtain control modules.
Why Lithium Batteries for Smart Curtain & Door/Window Sensors?
Door/window sensors typically stay in low-power standby mode for long periods, then need instant power when a trigger occurs.
Smart curtain modules may require stable output for wireless communication and motor/control logic depending on design.
Compared with disposable batteries, rechargeable lithium batteries can maintain consistent voltage output,
ensuring devices stay online without interruption while reducing replacement frequency.

FAQ
How long can a lithium battery power a door/window sensor?
Runtime depends on standby current, trigger frequency, wireless protocol, and temperature.
Many sensor designs can run for months to years when optimized for low power.
Do smart sensors support rechargeable batteries?
Yes. Many advanced sensor designs integrate rechargeable lithium batteries with USB-C charging to reduce replacement costs and improve user convenience.
Which chemistry is better for smart home devices: Li-ion, LiPo, or LiFePO4?
LiPo is ideal for slim and flexible shapes, Li-ion is a cost-effective general solution, and LiFePO4 offers strong stability and long cycle life.
The best option depends on your voltage, enclosure size, and safety requirements.
Can PKNERGY customize the battery size and connector for my sensor or curtain module?
Yes. We support custom battery pack design including capacity, dimensions, wiring harness, and connectors to match your product structure and assembly.
