What battery is good for electronic door locks?

Generally speaking, most of the current electronic door locks use four 5th batteries, which are generally used in hotels.

When selecting batteries, it is recommended to use alkaline batteries, which have long service life, good safety and are not easy to leak. Second, try to buy some big brands of batteries on the market, and the quality is guaranteed;

This seems to have no choice! At present, most door locks are made of No.5 battery, and only a few companies in China are making them, such as Fu Nan, Changhong and Mustang. There are many fakes in Fu Nan, which are used for door locks, and the security is worrying. Changhong and Shuanglu are still recommended!

In fact, the price of electronic door locks is relatively high, so it is recommended to use professional electronic lock batteries.

Although the technology of ordinary alkaline batteries is very mature now, the quality of batteries is also very high. But when it comes to the stability of electronic locks, professional electronic lock batteries are better. As far as I know, the battery of Shuanglu electronic lock in the picture mainly adopts special sealing ring to prevent leakage, so as to achieve real leakage and protect the door lock from corrosion and damage.

At the same time, it is also very important to discharge normally and stably in extreme high temperature and low temperature environment. If it can't be discharged stably, there will be embarrassment of not opening the door.

Probably only the real domestic brand of Shuanglu battery can produce this kind of electronic lock battery which can discharge stably for a long time.
