The Blink Video Doorbell is wireless, with Battery power, that truly does not require wiring. This helps easily install and move it somewhere else. It runs on AA non-rechargeable batteries, and it can get a bit of extra energy from the doorbell wire.
Specifically it uses AA 1.5-volt lithium non-rechargeable batteries. One must use lithium, not alkaline. Do not mix used and new batteries or different kinds like lithium and alkaline together.
Blink Doorbell Batteries and How Long They Last
For installing or swapping the batteries, first remove the back cover. Then place the AA 1.5-volt lithium batteries in the slot with poles facing right. Then push the top of the back cover beside the small screws and the bottom part of the cover, until it clicks in place.
The Blink Video Doorbell belongs to the second generation of smart safe doorbells. It gives high-quality HD image of the visitors, 1080p HD video daytime and overnight with infrared mode, plus two-way audio. It works with Alexa, allowing you to answer the door by means of your phone.
It also offers custom warnings, wider view and other safe improvements.
About the claim of Battery life, officially it reaches up to two years with standard settings and usual usage, when tied to Sync Module. Two AA Energizer lithium batteries and the Sync Module come together in the package. Even so, the duration depends on the settings of the device, the usage and the weather conditions.
The Sync Module improves the link to the net and also extends the time of the Battery.
In real life, the results really range. Some users reach almost nine months with one set of batteries. Others mention six months for there Blink outdoor cameras with more than forty triggers daily.
But some have batteries that last only three weeks or even one month. One user said that his batteries die every three days. The two-year promise probably counts for light usage without a lot of movement or taps.
For Blink devices, the right and only suggested ones are Energizer Ultimate Lithium AA batteries, because they match the energy needs of the devices. Some users kept Energizer lithium ones for three years without change. There also exist third-party rechargeable 1.5-volt AA lithium ones, but finding reliable brands is hard, because the devices need stable 1.5-volt output.
The Blink app shows the level of the Battery on the main page and the settings screen of the doorbell. Warnings send when the energy drops. Amazon added the Sync Module, daytime colors and event reactions to help save the Battery life.
The doorbell itself can connect to already existing doorbell wire in 16 to 24 volts forextra energy.
