Advantages of using button batteries:
1. Mature battery technology: The button battery was developed in 1942. After continuous optimization, its performance and safety have become excellent. Even a disposable button battery can be used for up to 72 hours on these corc lights without any charging safety issue.
2. No waiting to use: If the battery is exhausted, you only need to replace it with a new button battery and the shoe headlights can be used immediately, especially suitable for lighting in emergencies.
3. Longer use time of the product: When the battery is exhausted, just to replace the battery, the shoe croc lights can be used permanently, which greatly reduces the risk of discarding the entire product due to battery damage.
