Energizer Industrial 9 Volt Batteries, Alkaline 9v Battery (12 Count)

Works as expected. I purchased these since the price is much better than in local stores.

I use these batteries in some vintage Cetec Vega wireless microphones that use 9V’s and are notorious for being battery hogs. Each time I use these microphones, they’re on for at least three hours at a time. The Energizer Industrial batteries still read slightly above 8.5V on a multimeter even after three or more sessions (about 9 hours of use). In other words, these things last forever and are about the best options on the market for live use. These batteries are also more of a normal size and fit these microphones pretty well, too. I used to use Procells, but when those started getting sketchy in terms of reliability, I switched over to these Energizer Industrial batteries. The Energizers have never leaked, and I’ve never had a dud. In short, I highly recommend these. For what it’s worth, the AA and AAA cells are also fantastic, too.

Name brand batteries are mostly all the same. This is a good battery at a good price.

Batteries are good value but box was not taped and batteries were scattered throughout loose the packing box which could be a safety hazard

The only batteries I use in my Cobra mods. They are strong enough to last quite a while, I can usually get several shows out of them before I swap them out for some fresh ones. The price is also great and I’ve never had any issues with leakage or corrosion.

seems this has a higher charge than the Procell which out of box barely shows green above the useless

These are the same batteries I was going to buy in the store but cost less because they came in bulk packaging. That actually worked better for me, since I needed a bunch to replace them in smoke detectors. It's a lot less effort and trash getting them this way.

still top quality product and fast delivery

These batteries last a long time, and the price is good. (Although I'll mention that I'm not as convinced of the most recent batch.. still better than most, but maybe not as great as I've experienced on previous purchases) I use them in my guitar and these seem to last the best. I don't have to change them every two weeks! I gave a 5-star for "presentation", but I don't even know what that means. It's a simple box of batteries! What more could I want? Please don't junk it up with a bunch of fancy and environmentally horrible plastic packaging!

Aún no he tenido la oportunidad de probarlas, aún así pongo esa calificación por el precio, soy músico y requiero siempre baterías 9v para el sistema inalámbrico de la guitarra e in ears y creo que esta fue la mejor opción ya que en tiendas son super caras.

Desafortunadamente 2 Baterias del paquete no servían. No lo sabía hasta que las vas utilizando. Hoy me di cuenta que un par del paquete no funcionaban. Prueben todas al momento que les llegan.

Good battery, good price. I use them in my smoke alarms and when I take them out to change them, I test them. After a year in the smoke detector the batteries retain 80% or more charge so I can use them in toys and such.

Good value, genuine + use before date is 4 years from getting them
