[Details of Safety Measures]
● Battery Safety Measures
1. Adoption of High-Quality Batteries Compliant with International Standards
The batteries we use comply with the international safety standard 'IEC62133-2' and undergo evaluation tests by third-party organizations.
2. Electrical Safety Control via Battery Protection Circuits
To prevent events that put batteries in dangerous states, voltage is detected in real-time, and current is safely controlled.
3. Overcurrent Protection via Current Suppression Function
In the event of a rapid temperature rise due to battery trouble, the electric current is limited to a safe range to prevent overcurrent.
4. Safety Stop Function for Internal Pressure Rise
In the unlikely event that gas is generated inside the cell, a pressure valve stops charging and discharging to suppress the risk of smoke or fire.
● Comprehensive Product Safety Measures
5. Electrical Safety Control via Product-Specific Protection Circuits
The product ensures stable operation and high safety by responding to abnormalities during charging, such as overcurrent or overcharging.
6. Execution of Original Product Reliability Tests
We conduct and evaluate strength tests, such as drop, vibration, and impact tests, as well as environmental tests for temperature and humidity.
*Caution: While we strive for safety, unexpected accidents may occur depending on usage (e.g., impact, water exposure, disassembly, or modification). Please read the instruction manual carefully before use.
[About Disposal and Recycling of Lithium-ion Batteries]
When disposing of lithium-ion batteries, collection and recycling are mandatory under the Act on the Promotion of Effective Utilization of Resources. As a member of JBRC, we design our products so that batteries can be removed to promote recycling. Please follow the 'Battery Removal' instructions in the manual and take the battery to a recycling partner shop.
