1. How to replace the battery in a fingerprint lock.
1、Manually remove and replace battery panels.
If the fingerprint lock's battery is depleted, it will need to be replaced. Here's how to replace the fingerprint lock battery:1. Use a screwdriver to remove the screws.2. Remove the screws and open the fingerprint lock battery compartment.3. Remove the depleted battery.4. Insert a new battery, making sure to observe the correct polarity.5. Reinstall the battery compartment and secure it with the screws.
2、Directly open the battery box for replacement.
Some fingerprint locks have a battery compartment on the back that can be opened directly. Insert the appropriate number of No. 5 alkaline batteries into the battery compartment, ensuring correct polarity, and when powered, you will hear a "beep" indicating a successful replacement.
Editor's Note:
The fingerprint lock battery is depleted. Some batteries are not replaceable, and these are typically lithium batteries. When depleted, no replacement is necessary; simply charge the battery. If the battery is nearing the end of its lifespan, it is recommended to have it replaced by authorized service personnel, as improper handling can lead to errors.
Two. When replacing the battery in a fingerprint lock, what should be paid attention to?
1、Do not mix new and used batteries.
In reality, it's simply a matter of replacing the old battery when it's depleted. The battery's condition during use, specifically when the voltage falls below the standard, can cause leakage due to internal chemical reactions. The liquid inside the battery is highly corrosive and can damage the components on the fingerprint lock circuit board, leading to poor contact or complete failure. Additionally, it's best to replace all batteries with the same brand.
2、The positive and negative poles must be correctly oriented.
This is actually a relatively simple process. Anyone who has installed batteries will know that the smooth side of the battery presses against the spring, and then a slight pressure is applied to secure the protruding points within the battery compartment. However, some fingerprint locks have battery compartments with a capacity of 8 batteries, but they can still function normally with only 4 batteries installed. This type of installation requires all 4 batteries to be placed in a single location, creating a circuit. This can be done on the left or right, or up or down.
3、After installing the battery, be sure to check it.
Many friends immediately close the battery compartment after installing the fingerprint lock battery, and then try to use the fingerprint lock. If it works, they don't pay attention. Sometimes, they even close the compartment before the fingerprint lock's front panel keyboard lights up. This is actually an incorrect practice. After installing the battery, we must allow the fingerprint lock to run normally for a few minutes, then touch the newly installed battery. If you can feel it is noticeably hot, it indicates that the fingerprint lock's voltage exceeds the rated voltage of the battery. In other words, this battery is a low-quality product and needs to be replaced with a new one. Otherwise, the overheated battery will quickly drain, which is equivalent to using a new and old battery together.
