They are as described and working fine in gate opener

I have a flashlight that uses the 123A batteries and it is very bright. It seems to have a long life in this application. I have used Voniko batteries before and have always had good results.

I purchased these in June 2023 and used it immediately. Fast forward to Nov 2025 I thought the battery was finally draining so I decided to switch to a new one only to find this one was starting to split. Not sure why it has but I bet I’ve used it for far too long 😅 Amazing battery life for my ceiling fan!
