Customer Ratings & Reviews

10 Year Shelf Life is great! I am very satisfied with my purchase! This product is great, delivers superb performance, reliable, and lasts longer than other brands! The product meets my expectations!

The battery is great. I recommend you guys to buy it.

Get a Lithium-Ion 9v, and that'll probably last you the lifetime of whatever you put it in.

Excellent batteries, many to choose from, plus other sizes,etc. you may need. Great place to shop. Many great deals, etc. All you need is to go to Best Buy for you Gift cards for many other restuarants, etc. The Best.

I rely on Energizer lithiums for essential alarms and lights. Never leak or fail. Well worth it.

Long lasting is a under statement of the year lol Thanks Best Buy

There really are no other batteries better than Energizers for long life under load and no worries about leakage (unless you store the depleted batteries for a very long time). One wrinkle with these 9V batteries is that, because of their unusually square corners, they won't fit in some devices unless forced and sometimes, not even then.

I am a fan of Eveready Advanced Lithium Batteries. I originally discovered them when I purchased Nest Aware Smoke and Carbon Monoxide detectors. Batteries were included with this product. The most notable qualities are that they have dependable solid performance at lower temperatures where alkaline batteries will fail and these 9 volt batteries are completely encased in plastic for heavy duty and leakproof properties.

Exactly what I needed for my work tools, makes them last longer.

Works Great so far in my smoke alarm. No more beeping in middle of the night.

Excellent Choice in long lasting batteries at Best Buy value pricing.

Great 9 volt battery for all your radio or electronic devices

This is the only battery to buy for smoke alarms, electrical combination locks, and devices you don't want to change the battery every 3 years. This has a 10 year life span!! The price is definitely higher but who wants to get on a ladder every three years?

We like to buy the lithium 9 volt batteries as they last longer in the smoke detectors.

I buy four a year for CO2 detector and smoke detector because they last.

Good battery, definitely it will last 10 years,I am expecting same

Expensive but the best for all pro work and gear we use on set.

A bit pricey but does last a good while and worth it.

I was looking for the absolutely best, longest lasting battery for my smoke alarms, and information I gleaned from the internet, listed this brand and model as the longest lasting on the market. Since I have 9 smoke detectors in my house, and a elderly dog that is frightened by the beeping of weak batteries, I bought several of these batteries and will gradually replace all of the old ones at the first beep. Hopefully, these batteries will last long enough to see me through the next few years.

Because Lithium "primary" cells last longer than Alkalines, AND can deliver more current, AND have very long "shelf lives", I've switched to using them in my remote controls and Anything Else that uses Alkalines. Yes, they cost more than Alkalines, but I haven't had to worry about BATTERY LEAKAGE like I do with Alkalines and I have high confidence the Lithium-powered device will still work even if it's been "idle" for months at a time.
