Best batteries!
4 years ago
[This review was collected as part of a promotion.] With two toddlers, we always need batteries on hand and have tried a lot of different brands and types. The Energizer Ultimate Lithium 9V batteries are by far the longest lasting and best batteries available in this size! Energizer is a great brand of batteries that never disappoints us and this 9V is no different. Highly recommend these batteries!
Yes, I recommend this product.

Long lasting
4 years ago
[This review was collected as part of a promotion.] so, I put this in my bark deterrent box which usually on average...with average batteries lasts about a week because I have a chihuahua who will even bark at the wind blowing so this thing goes off alot. We are going on 2 weeks now and the light is still bright like day 1. So this battery is definitely outlasying the ones I have used in the past.
Yes, I recommend this product.

Lasts for a while

[This review was collected as part of a promotion.] I got this for my flashlight. I have the big storm flaahlights. So far they have lasted i havent had to replace them. Its a good thing when you can rely on something to last especially during storms. We get them regular and the electricity goes out. The energizer brand as a whole is a great and reliable brand. I truly trust them in times of need!
Yes, I recommend this product.

Dependable product.
4 years ago
[This review was collected as part of a promotion.] The first thing that noticed was that this battery has a 10 year shelf life and the second thing was that is 100% leak proof! I always trusted Energizer Batteries but I'm certainly even more reassured that this the battery for me. I'm absolutely installing them in our smoke detectors and everywhere else that calls for this type of battery.
Yes, I recommend this product.

High Quality Battery

I used this in my garage clicker which I use on a daily basis and the battery powers it well to give it the energy I need and seems long lasting. I like that the battery was easy to install and is working well, and this is a brand I definitely recommend.

Perfect for big toys
4 years ago
[This review was collected as part of a promotion.] Energier Ultimate lithium battery is perfect for toys or other stuff which uses 9V. As per packaging it have 10 years of shelf life, also it performs in extreme temperatures i.e. -40F to 140F. I tested it in 35F and it works good. I have used energizer batteries in past and i am sure this battery will also work up to my expectations.
Yes, I recommend this product.

Ten year shelf life yay!
4 years ago
[This review was collected as part of a promotion.] Always like energizer brand batteries. I was definitely happy when I saw this particular battery with 10 year shelf life....I always need batteries on hand and hate when they leak and corrode in storage. If you are type that has to have a stash of batteries (esp. those who live and get affected by storms), consider trying this!

Trusted brand taking it to a new level.

[This review was collected as part of a promotion.] Knowing we can rely on Energizer Ultimate Lithium 9V batterie in our RC Car remotes when racing is huge! The middle of the race isn't time for a battery to die and leave us hanging while other racers pass. We also use Energizers for our smoke detectors and other important electronics. A trusted brand improving their product.

Long lasting batteries
4 years ago
[This review was collected as part of a promotion.] I tried the Energizer Ultimate Lithium 9V batteries in my Tens unit, which is used for electrical muscle stimulation for back injuries. I am very pleased with the life and power of these batteries. My Tens unit seemed to run much better with these batteries verses other brands I've tried. Excellent battery for any use.

Thank you for allowing me to review these batteries.

[This review was collected as part of a promotion.] With so many options it can be hard choosing the correct battery. I'm so glad my instinct didn't fail me this time. Energizer battery works just as it should. Being that i needed it to replace my smoke alarms i need to be able to have a battery i can trust and know it will be there for me when i most need it.
Yes, I recommend this product.

Works great
4 years ago
[This review was collected as part of a promotion.] I needed this battery to change out an old one in my fire alarm. Energizer is well known for their long lasting batteries so I know this will last me for a long time coming. They are usually on the pricey side but if you want a good quality battery I would highly recommend going with Energizer.
Yes, I recommend this product.

Best Battery
4 years ago
[This review was collected as part of a promotion.] I recently received the Energizer Ultimate Lithium 9V Battery, and I am super impressed with the battery life. I will not have to change out this battery as often as I change out other batteries. The Lithium has twice the power of a normal battery, so I will be switching to these batteries!
Yes, I recommend this product.

Square corners
4 years ago
[This review was collected as part of a promotion.] Energizer is a great product. The shelf li of this lithium battery is 10 years which is a huge plus. The problem with this battery is the shape. The corners are not rounded like the traditional 9V battery which creates a problem with fit in some items. I wish the corners were rounded
No, I do not recommend this product.

[This review was collected as part of a promotion.] This battery is very durable and longer lasting. I used it for my smoke alarm and I don't have to change it for a very long time because that's how long it lasts. I will definitely recommend this to my friends and family and will buy this brand again for my other smoke alarms at home.

As expected!
4 years ago
[This review was collected as part of a promotion.] One thing about the Energizer brand, you can always count on great quality products. I prefer them over others. I use their 9 volt batteries in my smoke detectors for piece of mind. They would easily last over a year, but I change them every year just to be extra safe. Great company!
Yes, I recommend this product.

The best 9 v battery.
4 years ago
[This review was collected as part of a promotion.] This lithium Energizer is quite a battery. It says it has a shelf life of 10 years and has the manufactured date on the bottom. It is 100% leakproof. It says it performs in temperatures from -40 to 140 F. The bright aluminum case looks nice. Too bad it has to go inside the devices.
Yes, I recommend this product.

So far so good
4 years ago
[This review was collected as part of a promotion.] It’s hard to review an item that is made to last a long time but so far so good! Seems strong and I hope it lasts as long as it claims in my smoke detector! Upon receiving it had fallen out of its packaging, it was not packed well, but does not seem to have damaged it in any way.
Yes, I recommend this product.

Energizer Ultimate Lithium 9V battery
4 years ago
[This review was collected as part of a promotion.] I Received my free to review Enigizer Ultimate Lithium 9V batterIt is more box shape than older 9volt batteries, which made it easier to hold onto while placing for use. Noticed it is slightly lighter than older batteries also, highly recommend for people to try for themselves.

[This review was collected as part of a promotion.] I use a TENS unit for back pain. When I have a flare up, it’s not uncommon to kill a battery in a single day. I was very pleased that this battery lasted almost 4 full days before I had to change it. These will be my go to batteries for my TENS unit going forward.

Keeps Going
4 years ago
[This review was collected as part of a promotion.] I used the battery in my fire detector in my house. Hoping it will last for over a year and not need to be replaced as often. The packaging was good and quality of the battery also looked sturdy. May need to buy a few more to put all over the house fire detectors.
