Excellent and good quality definitely buy this again

Value for its money, works as it should. Came package really good.

These is the best 9 volt Lithium batteries ever.Other brand 9 volt Lithium batteries are usually measure less then 9 volts.These batteries measure 9.6 volts, even under load.These will be my 9 volt Lithium battery of choice from now on.

The batteries seem to be of good quality. Both batteries measured greater than 9.6 volts. Using in smoke detectors. See how they are holding up in Fall.

A great price for the amount that you receive! I don’t know exactly how long these last compared to other 9 volt batteries but if they are anything like the other Amazon Basic battery choices, they should end up being a great value.

Makes my smoke detector stop beeping. That's all I ask of it.

Bought lithium for shelf life. These work in my stud finder just as well as energizer lithium at a significant discount. Funny to see they shipped in a large box/carton to prevent damage. Another good product with the amazon logo on it.

Rechargeables are not ideal for smoke alarms. So I got these. They are the exact specs for the rcommended batteries and I haven't had a glitch since

So far so good... bought as replacement for smoke detectors that are still functioning.

These batteries will save you money in the long run especially if you're using them for 18V PreAmps in active instruments. I've had no issues with the volume outputv whatsoever and will continue buying these. They're great in value in comparison to other more expensive brands.
