Batteries 123A Lithium 3 Volt

[2 years] Very versatile, You can use lithium batteries to power it

[8x AAA] Nothing beats these lithium batteries...they don’t die.

[6.9 x 2 x 1.3"] Great buy on quality 9 volt batteries. My smoke detectors use 9 volt batteries.

[1.5 lb] These lithium batteries are very light and last a long time. Charger works well too.

[1] I love the compact size of the charger, and it seemed to charge my lithium batteries quicker than my last charger.

[0.25 lb] Like the ability to change 2 batteries at the same time and keep them together. Thinking about getting another for my other two Lithium Ion batteries.

[ATX12V 585 W] Works just great. When you order be sure and get 2 - 9 volt batteries ... B&H didn't tell me this and they sold me one ... which meant I had to run out and get another to make it work.

[Alkaline] [This review was collected as part of a promotion.] These 9 volt batteries are packed with energy. A great battery that fits perfectly. I was able to use this battery in my smoke detector and it’s all fixed. Rayovac brand is one I confidently trust and know I can rest assured my batteries will keep working.

[+20 dBu] I am using this device so that the singer can monitor her voice through an ear bud which means she doesn't have to have monitor close to her mic. Also, she can adjust the volume to her liking. The mic can be passed directly through or it can accept a feed from the board or both at the same time. Very cost effective for the quality and usefulness. It can use batteries or a small power adapter. My only complaint is that it uses 9 volt batteries instead of AA's which are cheaper and last longer. But, I high quality 9 volt alkaline gives us about 6 hours of use.

[0.3] Many of the small electronic items I have are powered by 9-volt batteries. I like the way these were safely wrapped to protect the contacts. I spot checked several from the dozen-pack with a high-quality battery tester and found them all to be right up at the top. I would certainly buy them again when my current supply gets low.
