Appears very robust have needed to use it yet due to the battery in the doorbell is still going strong and as this spare battery was included as a spare. If the battery in the doorbell is anything to go by I can say it is very reliable and can see and hear everything within the zone, storage is sufficient and definitely value for money.

I bought this to go with my Eufy video doorbell and to avoid downtime when charging batteries. I keep one extra fully charged and just swap over instead of just one battery which would mean the facility not being available for a few hours. Worth buying.

Firstly, installation was a breeze. With clear instructions and minimal hardware required, I had it up and running within minutes. The versatility of being battery-powered meant I could place it anywhere around my front door without worrying about wiring or power outlets.The design is sleek and modern, seamlessly blending with my home exterior. The weatherproof construction ensures durability against the elements, a feature I particularly appreciate given the unpredictable weather in my area.One of the standout features of the eufy Doorbell is its advanced motion detection capabilities. With customizable zones and sensitivity settings, I receive timely alerts whenever there is activity around my doorstep, providing me with peace of mind whether I’m at home or away.The video quality is impressive, offering crisp 1080p resolution with a wide-angle lens that captures every detail. Whether it’s daytime or nighttime, the infrared night vision ensures clear footage, essential for monitoring activity during the evenings.Additionally, the two-way audio allows me to communicate with visitors or delivery personnel remotely, adding an extra layer of convenience and security.Battery life has also been impressive, lasting several months on a single charge depending on usage. The accompanying app provides real-time notifications and allows for easy access to recorded footage, making it effortless to stay connected and informed.Overall, the eufy Doorbell Battery has proven to be a reliable and efficient addition to my home security setup. With its easy installation, advanced features, and robust performance, I highly recommend it to anyone looking to enhance their home security system

So much better having the removable battery as i dont have to take the camera down to charge lasts a long time could be abit cheaper but i am happy

Ideal to have a spare battery to have while charging a battery. Genuine Eufy quality.

The Eufy doorbell \ cameras are great. Battery operated means no messing about with wires which is also great. The downside is sometimes you need to take the battery out to charge it, which means no doorbell while it's charging!Buying this spare battery means I just swap the battery out, put the dead one on charge and my doorbell stays always on... perfect

Fits properly..

I love how easy it is to keep my Eufy doorbell cam powered with two rechargeable batteries in rotation. Swapping them out takes just a minute—no fuss, no hassle! The quick-release design makes it a breeze to pop one battery out and another in, so my doorbell is always ready to go. Having two batteries ensures no downtime while one charges. Highly recommend this setup for anyone with a Eufy doorbell looking for a seamless, reliable power solution!
