D.C 1.5 Volt Coin Batteries

Great buy on quality 9 volt batteries. My smoke detectors use 9 volt batteries.

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.

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.

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.

I use this to recharge the batteries for my Nikon D500. I have only charged two at the same time once - when I first received with two new batteries that were down to about 15%. I like the fact that it shows the capacity of the battery, each individually. There is also a port for charging a USB device (5 volt - 2A output) I have not used and it also came with a short cord to connect to the 12 volt outlet in the car so batteries can be charged on the way to or between shoots which might be necessary when using Nikon's adapter for wireless flash as it does pull the Nikon D500 battery down rather quickly.

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.

[This review was collected as part of a promotion.] I like to keep an extra set on of 9 volt batteries on my work truck for various uses. I have a few tools I use regularly that require a 9 volt so always good to have a spare. Sometimes there are other reasons I need a 9 volt, smoke alarms, water alarms that need a 9 volt so this is a perfect solution. 5 year power guarantee is perfect, worst case even if it last for half that under normal usage it buys ample time for what I need. Happy with these batteries!

Versatile and rugged bag. Lasts forever unless you abuse it (multiple 14.4 volt, 6 ah batteries, leaky silver cells plus cables, and tools that you constantly drag in and out of vehicles). On the other hand, if you carry lenses, cameras, microphones, or other delicate gear-I have one model (F2 , forrest green with leather trim, sadly, no longer made) that is still useful after 30 years.

Lets me pick out the batteries that need more work or are just done. I have real good volt meter but it takes a lot less time to put them in the charger, that I have to do anyway. I have a bunch of the same batteries so its helpful have the LCD indicate which one is not as good. Plus you charge up to 8 at a time each and each gets a full charge.
