Lithium Button Cell Battery Cr2450

This lithium battery is very reliable.

I recently purchased the Energizer LR44 Alkaline Button Cell Battery for a digital thermometer and a few other small devices, and I’m thoroughly impressed. These batteries have exceeded my expectations in terms of longevity—they’ve powered my devices for much longer than expected, especially compared to other brands. The power delivery is stable and reliable, ensuring consistent performance without any unexpected power drops. Additionally, the LR44 size fits a wide range of devices, making it a versatile option. I’m very satisfied with this purchase and will continue to use Energizer for my battery needs!

I have four different keychain flashlights: - a button-cell light with a switch that activates way too easily (in my pocket, bumping against keys, etc.), and so wears out the battery prematurely. - two different brands of lights that each use a AAA battery, have a twist-to-turn-on function, and neither of them have multiple brightness settings or a rechargeable option. - this one. When looking at the other three, it's easy to see why this is my favorite.

This manual flash has everything I need and especially like the lithium battery. just bought a second unit.

Long lasting Lithium battery makes it cost effective.

Lithium without the need to recharge. Excellent long-life battery.

I bought one, have to buy another, great sony lithium battery.

This 4-pack of lithium button batteries is a perfect way to get those tuners shining brightly again. B&H gets them to you cheaper than any other option. Trust me -- I'm a smart shopper!

The Watson Lithium Battery is a great backup for a Nikon battery. It lasts as long and makes a great back up for a Nikon battery.

Purchased 2 weeks ago... no problems so far. Easy install (Base to wall with 2 mounting screws. Then attach two existing old doorbell button wires to the new camera head; then snap camera head onto the base.) ... Would like to have seen a better security feature where the camera head attaches to the base. I like that the power from the wires keeps the battery in the camera head charged, and also rings my existing indoor chime when the camera outdoor button is pressed, as well as alerts my cell phone. Also like the bottom facing camera to see the landing in front of the door for any package deliveries. (Very clear images). Unit has lights for improving night vision recordings that are activated by motion detection. They can be programed to turn on or off. Camera mode allows for All motion or Human motion. The All setting shows and records every vehicle passing by. The Human setting shows and records only people. The recordings last about 6 seconds or until no motion is detected. Each recorded clip is stored in the unit and can be viewed/deleted at anytime. Disliked recording every vehicle going by. The Doorbell unit alerted my cell phone when I was 30 miles away... wasn't sure it would do that, but it did. I haven't used the voice thing yet to talk to someone at the door, but seems to be a good feature. There are many more good features but probably one of the best is .... NO subscription cost.
