These seem okay, no duds so far. They are lithium and using in smoke detectors to prevent annual battery changes. If they get low, I'll get the dreaded low battery beep. This way I am not trying to change these every year. So far, so good, but it's early. past experience with this brand has been good.

These non-rechargeable 9V Lithium Batteries are reliable and long-lasting. The shelf-life is 10 years. I like lithium batteries because they are not supposed to leak. Overall, these appear to be good lithium batteries at an affordable price. Would recommend.

So far so good.

I have been using these in the field. My normal go to 9volt batteries tend to last only a few hours with my equipment. These batteries are lasting all day of useage. Very happy them. Pricey comparing to most batteries, but being lithium, a good value.

VERY Good Batteries ... reasonably priced, connecters are nicely made. Great quality overall.

Great long lasting battery for my garage door panel opener.

I've only used 2 of these in our smoke detectors so far, but they've lasted almost 3 months and when I test the detector it still shows that they are working. It's a good price for Lithium batteries.
