Customer Ratings & Reviews

Awesome buds great sound and long lasting battery life.

This is the long lasting battery I brought for my lockbox. Can’t go wrong with this excellent battery.

Used on my rode vid mic pro at an event. Works like a charm.

Definitely would recommend this product for purchase

One of my biggest pet peaves is hearing the constant chirping of fire alarms with low batteries. To extend out the time as long as possible, I turn to the Energizer bunny. No more chirp.

Works great I love how long it lasts for lights and stuff.

Battery is just as advertised. Works great in my smoke detector. I definitely recommend this battery. I will be purchasing additional batteries in the very near future

What can I say? This is the best brand of batteries on the market.

What can I say, they are great batteries. They last a long time.

The Energizer Max 9v batteries are a must to have on hand. I always make sure to get them at a great price and they are great batteries for the smoke alarms.

Always needed for smoke detectors, etc. I usually have some of the more common sizes around, but the 4 pack is perfect to have a back up battery when you need it.

Worked perfectly in my smoke detector. Also used it in my speaker

Always a good idea to buy batteries where you know the stock is rotating regularly. The same batts in a drug store might sit on the shelf for months, but at Best Buy they're moving out.

Good price compared to other stores and oddly enough these batteries are harder to find these days.

These were originally priced for a lot more, but they price matched another online store that I found that was selling these Energizer 9Vs for almost half the regular price!

Always good to have a great 9 volt battery on standby from Energizer.

Use these in my guitar with active hambuckers. Last forever.

I bought these for my Kidde smoke alarms. They're the recommended brand for them. They should last for a year.

I am usually Duracell battery fan. But after I try Energizer, I see a difference between two types of the battery. It actually lasts longer than Duracell.
