Which is better, dry battery or lithium battery with fingerprint lock?

Introduction Which is better between dry battery and lithium battery in fingerprint lock? Today's fingerprint locks are all battery powered, but some fingerprint locks are powered by lithium batteries. They use rechargeable technology and the batteries are heavy.

Which is better, dry battery or lithium battery with fingerprint lock?

Current fingerprint locks are all battery powered, but some fingerprint locks are powered by lithium batteries, which use rechargeable technology and the batteries can be reused. However, most fingerprint locks are powered by dry batteries and run out of power. directly. So, which of these two types of batteries is better for fingerprint locks, and which is more reliable? Let the editor break it down for you below!

Comparison of two batteries

1. The dry cell specifications are exactly the same. Although there are AA and AA batteries, all brands of AA batteries and AA batteries have the same specifications. The same thing, you don't have to worry about whether this company's battery can't be used by this company. So even if the fingerprint lock is discharged, you canQuickly buy a new battery and easily replace it. But if there is a problem with the lithium battery, if you want to buy it, you need to look at various parameters and make sure it matches the fingerprint lock, which will make the purchasing process very complicated if You are unlucky. , the lithium battery with the previous specifications will no longer be produced by your own company. The fingerprint lock has become a pile of scrap metal.

2. Typically, a fingerprint lock's battery is replaced almost every six months to a year. User don't need to worry at all until the fingerprint lock battery is low and no longer rings. , the lithium battery discharges relatively quickly, so users need to replace the battery frequently. Charging the fingerprint lock is very inconvenient. Additionally, if users are a little ocrun out and forget to recharge, they will often find themselves in a situation where they cannot return home.

3. Although lithium batteries can be recharged and seem to be more cost-effective, if you calculate carefully, this is not the case: fingerprint locks typically use 4 to 8 dry batteries, and a fingerprint lock can use up to 'at 4 to 8 dry batteries per year. It only uses 16 batteries, and even 16 Nanfu batteries cost only 32 yuan. The cheapest lithium battery costs around 60 yuan. The lifespan of this lithium battery is less than 2 years, plus the cost of each charge. So do you think lithium batteries are really profitable?

4. Lithium batteries also suffer relatively large losses during frequent charging and discharging. It is very likely that the battery is leaking and causing an internal short circuit in the fingerprint lock. SIf you encounter a poor quality lithium battery and it explodes while charging, it is not impossible.

Editor's Summary:

In general, the use of dry batteries in fingerprint locks is more convenient, less inconvenient, more cost-effective and safer than batteries lithium. As far as current technology is concerned, the use of lithium batteries in fingerprint locks is impractical, expensive and unsuitable.

The pin definition of the smart door lock lithium battery is as follows :

< p>1. Positive Pole: The current coming out is the positive pole, marked with a + sign.

2. Negative Pole: Current flows in the negative pole, marked with a - sign.

3. Dry Battery Model: You can use 4 standard AA dry batteries. There is no need to distinguish battery brands.However, it is not recommended to mix new and old dry cell batteries, nor to mix multiple brands. /several models of dry batteries.

4. Charging Lithium Battery: It is recommended to use 5V/2A charger and the charging time should be 5-6 hours.
