Customer Ratings & Reviews

Use these for work on a daily basis, work good and long lasting.

Just needed some batteries and found some at a great price. I had a $20 credit there I thought I could use up before it expired. I guess I didn't know how it worked. Just got the bill for the purchase and it's for the full price.

Delivered fast batteries fresh works well good value

This are the typical batteries that you will need for remote controls cars. I have bought them for two cars and so far they are lasting a good amount of time. Totally recommended.

Works great! Use it to power my smoke detectors with no issues!

Needed 9 volt batteries that actually last a long time so I could use it in my smoke detectors. Haven't had any problems since and it seems to last longer than other brands I've used. Has a decent shelf life as well if not immediately using it.

I use these batteries for the fire alarms at my home. They last a lot longer than regular batteries. I would give it 5 stars, but these batteries are super expensive. I'm too lazy to change the batteries often, so I was willing to spend the extra money.

lol I just want the 400$ gift card reward don’t mind me. But if I’m being honest these batteries don’t die they’re legit invincible.

Long lasting and powerful battery for all applications

Perfect for our smoke detectors. We replace them every six months.

Great battery for smoke alarm. I've used these before they lasted over a year.

I always keep 9 volt batteries on hand and now is the time to change your batteries in your smoke detectors. I change them in the carbon monoxide detectors too just in case. Best Buy usually has the best prices and I order the batteries from them.

The Energizer Max 9 volt batteries were exactly what we needed to insure the smoke detectors in our home were ready for any emergency. We are aware of the necessity to replace batteries regularly. We always keep replacement Energizer batteries available when needed for the many devices in our home which are battery dependent.

pretty decent price, confident I have a good battery

Work like a charm. Would recommend to anyone. Good price too

Fair priced good battery. For basic use in karaoke mics

[Employee of bestbuy] I have always gotten Energizer 9V batteries for my guitar pedals and they have never failed me. Great price and last a long time for guitar pedals.

Got some batteries for the smoke alarms througout the house. I change the batteries every year just as a good habit. They probably last much longer and it's probably a bad habit on my part but I just feel better because it's for the smoke alrms.
