FF-109 3-Color Lead-Acid Battery 250mAh with Plug Electric Mosquito Swatter
This product uses a miniature sealed lead-acid battery. Lead-acid batteries are widely used in portable electronic devices, emergency lighting, and low-power power tools due to their mature chemical system, low cost, and stable voltage output. Compared to lithium-ion batteries, miniature lead-acid batteries exhibit more stable performance at low temperatures and have a lower self-discharge rate, making them suitable for scenarios like mosquito swatters where intermittent high-voltage discharge is required. The lead-acid battery in this miniature electric mosquito swatter employs a constant voltage and constant current charging mode to extend battery life and prevent overcharging. A built-in charging protection circuit monitors battery voltage and temperature in real time, automatically disconnecting the charging circuit when overvoltage or overtemperature is detected, ensuring the safety of the battery and the entire device.
