4 Lr44 1.5 Volt Batteries

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

[Alkaline] I really like that these 9 volt batteries have plastic covers for the +/- contacts. This allows me to place spares in my camera bags without needing to find a bag or box to prevent a battery from shorting out.

[1x 9 V] We've been very satisfied with the life of these batteries in our wireless microphones. Where a standard 9-volt would last for about 3 hours of use, these batteries last 7-8 hours without a recharge.

[0.125 lb] Some cameras, right out of the box, must be charged through the USB port - inconvenient if you have back up batteries. I purchased this unit from B&H for my Sony A7 and am glad I did. It is far more versatile than most chargers. Apart from 110 volt capability, it has a 12 volt lead for automotive use and as if that weren't enough, there is also a USB port. As usual, the B&H price and service were the best. Watson also offers a line of replacement batteries, and the one for my Sony is excellent - no problems!

[Orange] 9-volt batteries are the worst to store as they positive and negative terminals are close together - too easy to short circuit and run them down. This is a great idea and the execution of making it is very good. Solved a problem for me - and so reasonably priced! Thanks guys!

[1.275 lb] Great for charging multiple batteries and the ability to charge from a 12 volt source is great for when you are traveling and need to top off your batteries.
