I'm trying these out. Tired of throwing out used up batteries. It's 2024 for crying out loud...Update 12-14-24:These work great 👍Long lasting and easy to recharge.I use them in my multimeters and acoustic guitar pre-amps. So easy! Good value!

translucent light, great capacity
I got better life out of these, than stated run time with alkaline battery, using a wireless microphone receiver. I love the translucent light in the end, to show the charging state.

One of the batteries would not charge over 8.7 volts. The rest of the batteries were good over 9.0 volts charging.

9 volt rechargeable batteries
These rechargeable batteries are very well designed and the dual charger is a plus. This kit cost less than 2 name brand batteries and will save me money. Definitely recommend.

Can't use them in active electronic devices
I have a guitar that uses a battery and I put one of these in it.My equipment sounded damaged, finally tried a regular battery and it was fine.They must put out some type of radiation, made my amplifier hiss like a weak radio station.These are useless to me now, not even sure if I want to trust them in the smoke alarms.Save your money, don't buy these!

Reasonable priced and they charded quite fast.
I bought 2 Lazy boy recliners for the wife laast week for her birthday. and the control boxes need 2 9 volt barreries to work as backup power in the control boxes. So I bought this 4 pack for them. The were reasonaly prices for 1300 mAh betteries. they arrived within a week and charged up in less than 2 hours. I how have them installed in the power supplies for the recliners. I have not had to use them yet but I will be sure they can return the recliners to home if the power goes out. I tried them and they got it "home but not very quickly. You got to do it fast or the controller suts down.

Three of them worked one didn't
I received these yesterday. I charged them all. I installed one of them in a stud finder, and it didn't work. I took it out and replaced it with another one, and it worked. I tested the other two and they worked fine. I have them now in my some detectors. I most likely will not buy these again.
