Fingerprint Padlock Battery Life and Charging Methods

Fingerprint padlocks, also known as smart padlocks, are a convenient and secure way to protect your belongings without needing a physical key or combination. However, like any electronic device, they rely on a battery to function and may need to be recharged periodically. In this blog, we'll discuss the battery life and charging options of fingerprint padlocks, using KENRONE Zinc Alloy Fingerprint Smart Padlock as an example.

Battery Life

The battery life of a fingerprint padlock depends on several factors, such as the capacity of the battery, the frequency of use, the temperature, and the settings. KENRONE Zinc Alloy Fingerprint Smart Padlock is equipped with a 250mAh rechargeable lithium battery, which can last up to 1 year on standby mode. The padlock also has a low battery indicator that flashes red when the battery level drops below 20%.

Charging Options

To recharge the battery of KENRONE Zinc Alloy Fingerprint Smart Padlock, you can use either a USB cable or a charging dock. The padlock comes with a USB cable that can be connected to any USB port, such as a computer, a power bank, or a USB adapter. The charging time is about 1-2 hours, and the padlock can still be unlocked during charging if needed. Alternatively, you can use a charging dock that is designed to fit the padlock and charge it more securely.

Tips for Battery Maintenance

To prolong the battery life of your fingerprint padlock and ensure its optimal performance, you can follow these tips:

- Turn off the padlock when not in use, especially for a long period of time.

- Avoid exposing the padlock to extreme temperatures or humidity, which can damage the battery.

- Clean the fingerprint sensor regularly with a dry cloth to prevent dirt or oil from affecting the recognition.

- Use the low battery indicator as a reminder to recharge the padlock before it runs out of power completely.


Fingerprint padlocks offer a convenient and secure way to protect your belongings, but they also require attention to their battery life and charging. By choosing a reliable supplier and manufacturer like KENRONE, you can enjoy a high-quality and durable smart padlock that meets your needs. Remember to check the battery life and charging options before purchasing a fingerprint padlock, and follow the tips for battery maintenance to ensure its longevity.
