Customer Ratings & Reviews

I've used pretty much all of the major and store brand batteries, and this one by far outperforms them all. I use them in my daughter's diabetes monitors and this battery's life span is almost twice that of the store brands and at least 30-35% longer than the other major brand. Overall, this is the best battery out there....Definitely a must have!

Based on the measured voltages between these and the alkaline aaa batteries, I'd say these lithium batteries should last about 67 percent longer and will be more powerful in the first half of their life cycle. I've used them before and had no problems.

The lithium batteries last much longer than alkaline. I use them for my headlamp and miniMag lights when I'm doing a long section (200-400 mi) of the Appalachian Trail or when doing my annual week long Boundary Waters Canoe Area Wilderness canoe trip. Beats carrying the extra weight of a spare set of batteries.

I bought these Energizer Ultimate Lithium AAA Batteries for my new Philips - Voice Tracer Audio Recorder. I have not had to replace them yet, it has been a few months, and the recorder has been used almost daily! I would recommend these to anyone that needs long lasting batteries!

The Energizer Lithium battery lasts a long time. It’s the only ones that I use!

Good quality battery; long lasting. Will buy more.

Best batteries around. Last forever, well you know what I mean. Theu last a long time and are veri light.

I would have given 5 stars except for the price which is rather high :(. I needed (who doesn't right) batteries with a long life to prevent me from having to go out and buy them too often. They lasted pretty good; I bought them 1 1/2 years ago and looking back, they lasted 4 months in my controller; I play games 7 or 8 hours per week... Is that great? Is that disappointing? You be the judge.

Pricier now, but still the best battery. I use nothing else in my security cameras and thermometer transmitters.

I will only ever buy Energizer batteries. They last longer than every other battery in my opinion!

Very expensive, but I put their value-for-money very high because they last so much longer, and so I use fewer batteries. Not for everything, btw. These work best in electronics that draw hight amounts of power (high current), or are turned off for long periods of time between use but need to be ready for use at any time.

I'm glad Best buy had then near the checkout cause I wouldn't have remembered to buy AAA and my friend wanted some to so I'm glad they were where I could see them :) they last longer . ... .. I put them in my emergency flashlight, my real flashlight.

Best battery holds voltage for a long time but a steep price to pay. The voltage is measured higher than 1.5 VDC close to 1.7 VDC. I use the batteries in my remote controls such as my cable box. I use it in my remote temperature sensors. Lasts more than a year even during a cold winter months.

good batteries for a reasonable price will buy again

The best longevity of any brand. That's important on kids' favorite toys or hard-to-reach items.

These batteries are always good especially in my Nest Thermostat

Energizer are the best, and I can always count on Best Buy to have the best fully charged new batteries. The batteries are placed near the check out which is convenient and i am always reminded if I need any. Unfortunately they are pricey.

Good batteries use in almost anything. Perfect size and easy to use

These batteries last a lot longer than anything else on the market. The price is high but that's to be expected.

Good batteries at a good price, can always use more.
