One. How long can the battery of a fingerprint lock last?
1、From fingerprint lock processors
The lifespan of lithium batteries used in fingerprint locks is also significantly influenced by the quality of the fingerprint lock's processor. For high-quality imported fingerprint lock processors, a set of 4 batteries typically lasts for approximately one year; for standard domestic fingerprint lock battery processors, a set of 4 batteries typically lasts for about 8 months.
2、based on the battery type of fingerprint locks
The type of battery used in a fingerprint lock can also affect its battery life. Currently, the most common types of batteries used in fingerprint locks are No. 5 alkaline batteries and dedicated lithium batteries. A standard No. 5 alkaline battery for a fingerprint lock typically lasts for 8 months or more, while a set of 8 batteries can last for 16 months or more. Dedicated lithium batteries can last for 12 months or more under ideal charging conditions. Therefore, the lifespan of a fingerprint lock battery depends on the type of battery used.
3、based on the battery model of fingerprint locks
Currently, the batteries used in fingerprint locks are primarily alkaline batteries, with common models including 4-cell, 5-cell, and 8-cell alkaline batteries. The 8-cell alkaline batteries currently offer the longest lifespan, lasting over a year. 4-cell and 5-cell alkaline batteries typically last for approximately 8 months. The actual battery life of a fingerprint lock depends on the specific battery model selected.
II.Battery life of fingerprint lock
The lithium batteries used in fingerprint locks are rechargeable batteries. They can be recharged when the power is depleted. Regarding the number of times a lithium battery can be charged, the lifespan of the battery depends on the model and type used. However, generally, compliant lithium batteries can be charged approximately 800 times. This means that lithium batteries typically used in smart locks should last for about 3 years. However, due to the natural degradation of lithium batteries, it is recommended to replace them every 1-2 years. Some high-quality batteries may last longer than 3 years.
