Work great, haven't had then long enough to see how long they hold a charge but I imagine a while.

I bought these for my Blink cameras

Best batteries I have ever had .

Needed for my security cameras.

Definitely last much longer.

Have to use these in my smoke alarms as other batteries do not work

Best batteries to purchase. They outlast regular batteries.

The 18 pack lithium are the best price around there for my blinks so they last a long time

These batteries outlast any others I've tried.

Longest lasting batteries by far
