Smart electronic door lock battery selection guide: Which battery is best?

Have you noticed that electronic door locks are becoming increasingly popular? Even if you don’t have one installed at home, there is a good chance that several households in your neighborhood have already adopted this smart door lock. People prefer electronic door locks because they not only replace traditional buttons, but also have the convenience of remote control. Obviously, smart door locks rely on batteries to operate properly, but most users often overlook the importance of how to select backup batteries and properly maintain them.

Choosing the right smart electronic door lock battery will not only reduce the frequency of battery replacements and save costs, but it will also protect your smart digital door lock from damage caused by battery leakage, which can damage internal electronic components, circuit boards, or the battery compartment, thus extending the life of your smart door lock!

Smart electronic door locks - what are the power supply options?

Similar to other smart home devices, smart door locks have three main power supply methods: battery power, rechargeable lithium battery, and direct AC connection. It should be pointed out that the physical structure inside the smart door lock (such as the lock cylinder) will also consume a certain amount of power during operation. In addition, modern smart door locks are becoming more and more functional. They not only support up to six unlocking methods such as fingerprint, vein and facial recognition, but are also equipped with anti-theft functions such as real-time monitoring and instant messaging, which greatly increases the overall power consumption. Therefore, when choosing a power supply method, understanding the voltage provided by each solution and their respective advantages and disadvantages will help you better configure and maintain smart door locks.

What are the types of battery power supply? How to choose?

Generally speaking, batteries can be divided into three common types: carbon-zinc batteries, alkaline batteries and rechargeable batteries:

Carbon-zinc batteries are inexpensive, with an average voltage of 1.5V. Recommended uses: products with low voltage requirements, low power consumption and short use time, such as TV remote controls, air conditioner remote controls, toys, alarm clocks, etc.

Alkaline batteries are mid-range in price, with an average voltage of 1.5V. Recommended uses: products with high voltage requirements, large power output and long use time, such as electric shavers, wireless mice, remote control toy cars and other motor-driven products.

Rechargeable batteries (lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lithium batteries, etc.) are expensive, with an average voltage of about 1.2V-1.4V, and can be reused. Recommended uses: products with medium voltage requirements and high power consumption, such as sound or light-emitting devices, digital cameras, various portable devices and tools, etc.

Most smart electronic door lock batteries use AA batteries. Different brands and functional requirements determine the number of batteries required, generally 4 to 8. Considering that a higher voltage is required to drive the lock body during operation, alkaline batteries are better than carbon-zinc batteries and rechargeable batteries in voltage performance, and their electrode material utilization rate is higher. The capacity is usually 3 to 6 times that of carbon-zinc batteries, so they are most suitable for smart electronic door locks.

Most smart electronic lock brands recommend the use of alkaline batteries. If the use of non-recommended batteries causes damage to the lock, it may be considered user-caused damage and may not be covered by the warranty.

Smart electronic door lock - When to replace the battery? How long can the battery last?

Smart electronic door locks generally require 4 to 8 AA batteries. If the door is opened and closed 10 times a day, a set of 8 batteries can be used for about 10 months to 1 year, and a set of 4 batteries can generally be used for 6 to 8 months, but factors such as increased frequency of use and the addition of unlocking methods such as fingerprint recognition or face recognition will affect the battery life.

So, when does the smart door lock need to replace the battery? In fact, when the battery is low, the smart door lock will sound an alarm or voice prompt every time it is used until the battery is replaced. Most smart door locks will also provide a certain amount of time to notify you when the battery needs to be replaced. Rechargeable batteries are not recommended because their voltage is unstable and may suddenly run out of power, causing the lock to fail to remind you.
