1.5 V AA Rechargeable Batteries – Pack 4 Cropped, Ultra Fast 2H Charger, 3500mwh High Capacity Durable, Cycle Time Up to 1300x, Constant Output

I am now addicted to these rechargeable batteries. I use them for all my different technology devices. Works great if you have a blink system

Tengo poco tiempo usándolas, y funcionan muy bien. Cargan muy rápido y dan buena potencia. Espero que así se mantengan

Using these for my Outdoor Blink Cameras. I live in Canada where temperatures can go down to -30C (-22F), my Cameras are still working. For sure, it won't last as long as regular lithium batteries but these are rechargeable, I don't mind if they last half the time of regulars. In the end, this is an affordable solution for my cameras.

I got tired of always having to buy new lithium batteries for my game cameras so I started using these. They’re a little more expensive but boy do they pay for themselves quickly. I get a year’s use per charge in the cameras take hundreds and hundreds of photos and videos. They perform flawlessly in extreme temperatures from -40 to 90°F the lithium so they don’t leak. Definitely my favorite battery. They use to have a subscribe and save option, but that went away for some reason. Too bad because it made them actually less expensive than standard lithium batteries. Please bring that back!

Updated 12/09/2023 Battery died today after another week but the doorbell averaged 170 clips per day for the that week. Sucks the doorbell is ignoring my motion zones and keep recording cars driving by. Updated 12/02/2023 It's been a week since I've been using a set in my ring doorbell. I did another test to see the remaining mAh. Testing the two batteries in series had a remaining mAh of 721 which is 16% remaining as full it was 4543 mAh with (two cells in series). This may seems like it dies quickly which it did but my door bell gets triggered 100+ times per day. So I'd call that a win! I recently purchased this rechargeable battery for my devices and decided to put it to the test using the ET5410A+. The test results were impressive, with the battery delivering a capacity of 2189mAh, which is a commendable 94% of its rated capacity at a moderate discharge of 0.250 amps with a voltage of 1.48 during testing. I'm currently using a set of these batteries in my Blink Ring Doorbell since 11/25/2023, and they've been performing well. I plan to update my review once these batteries finally run out, but so far, I'm impressed with their performance and hopefully longevity. So far this rechargeable battery has proven to be a solid investment for my electronic devices. Highly recommended!
