Energizer Ultimate Lithium 9V Batteries (1 Pack), Lithium 9 Volt Batteries

I use these in my LED flashlights. These flashlights use a lot of power as they are really bright. This battery so far is the best balance of value and performance in these flashlights. Simple, easy to install and I haven't had any issues with leakage or swelling regardless of where I use the flashlights. A good overall product that I'm sure would work in other applications as well.

Ordered directly from Amazon as the seller and received a seemingly fresh battery. Measured ~9.6v at the terminals, and has an expiration date of 12/2035. As a point of reference, this order was placed in April 2026, so with a 10 year shelf life, it would seem like the battery is under 1yr old from the date of manufacture, so probably about as good as it gets considering the time of manufacture to actual distribution.

Regrettably I needed to replace the batteries in our Motion Sensors because they are a few years old, so I purchased Energizer batteries because they provide the quality that we need and the power that we expect at the price that we’re looking to spend. I would love if these batteries came in a rechargeable form like all of my other batteries. I love that I have enough rechargeable batteries that I can remove the dead ones, replace them with rechargeable ones and have plenty of spare batteries for all of out 30 of security cameras and additional security devices. Energizer batteries definitely meet and definitely exceed quality standards and our requirements.

Work as intended.

Decent batteries, expiration is 12/2035. They took more than a month to arrive. If you don't need them in a couple of days, order some.

Good Product. Works great and they last a long time. I never had any problems with them leaking like you can have with cheap brands.

Great price worth it

bought this to replace in a sony alarm clock, the previous battery expired in 2008! very nice upgrade

La compré por sus características en cuanto a la alta resistencia a temperaturas tanto frío como para calor ... Espero también sea más durable que la batería Energizer Max que utilizo normalmente

Light battery, good price, review say holds charge really well.

Die Beste, nicht mehr und nicht weniger. Kein anderer 9volt Block hält so lange.

Everything great with item

Buen producto
