Counterfeit Batteries – How Would I Know?
Reading the comments from many others made me concerned that the Energizer lithium AA batteries sold here might be counterfeits. These are premium batteries and might be an attractive target for cheap substitutes by unscrupulous suppliers. Still, the subjective comments from some that the batteries failed too quickly could be easily erroneous or biased. How would I know?I purchased 20 of these batteries and decided to put one randomly selected specimen to the test. My sample had an etched code of “0716” and a printed origin of Singapore – does that mean it was manufactured in July 2016? I called this sample “0716-01”.I found a product datasheet for the Energizer Ultimate Lithium AA (L91) here – http://data.energizer.com/PDFs/l91.pdf. One reads that this battery has a designed capacity of about 3300-3500 mAh (milli-Ampere hours) depending on the amount of current being drawn and the ambient temperature. For a current draw of 1000 milli-Amperes at room temperature, this battery is expected to run for about 3.3 hours (3300 mAh/1000 mA) before the voltage drops below 0.8 V.Looking through an assortment of power resistors in my electronics scrap bin, I found a 2.2 Ohm 5 W resistor that would do for a test. According to Ohm’s Law (V=I*R), this resistor will nominally draw about 700 mA dissipating about 1 W of power (P=I*V). At 700 mA, this battery should drive current through the resistor for almost 5 hours (3300 mAh/700 mA).The attached photo shows my experimental setup which used a Fluke multi-meter to measure voltage and a smartphone stopwatch app to measure time. I entered the recorded voltage into an Excel spreadsheet to compute the capacity and to produce the attached plots of voltage vs. time and capacity vs. time.Indeed, my sample Energizer Ultimate Lithium AA delivered a little more than 3100 mAh, near to the capacity stated by Energizer for this battery.Naturally I cannot vouch for the batteries delivered others, but I believe that I received legitimate Energizer batteries.
Li Battery review
I ordered some low temperature sensors for my two freezers, and they arrived with instructions to use Li batteries, as opposed to std. dry cells. Since I did NOT have Li batteries, I used “normal” batteries—-that held up less than a week in subzero temps. Purchased these batteries, all works perfectly!
Junk Most DOA.
Junk most were dead on arrival. Would not order from this seller again.
good price / poor staying power.
good price but did not work. they lasted about a month if that in all my units. my first order in a outdoor game camera lasted all winter.

Bought these batteries and they are 1 year expired
These are not Energizer - they are EBL - a complete rip-off
This is a TOTAL, ABSOLUTE RIP-OFF. The batteries I got are NOT Energizer Ultimate Lithium nor any other Energizer battery. They are a cheap EBL brand. They do not work in my noise cancelling headphones. Beside causing static in the headphones they simply stop the sound altogether periodically. I’ve found them not to work in other applications as well. <aybe they are very old stock and no longer have a charge.They are cheap crap and I am disgusted that I didn’t look at them as soon as I got the package. How Amazon can advertise Energizer and ship EBL is beyond my understanding. This is certainly a ding in the Amazon reputation.
20 of each you say? My package was a little light….
Buyer beware. There were only 17 AA batteries and 18 AAA batteries in my package. I hope this helps someone else not make the same mistake I did.
When they are ventilated, they perform well
Energizer 10 AA + 10 AAA Ultimate Lithium Long Lasting Leakproof Batteries BulkA great source of power and there were conveniently packaged and priced. I love Lithiums. When they perform to specs, they are quite a robust power source. Too bad there is sometimes an over-heating problem in a very few devices. Be careful of the devices in which you use them. Careful planning leads to a good performance and a successful experience.
Dont bother using for puck lights!!!!
These lithium batteriesI bought for my 12 puckLights that take 3 aa batteriesEach..they did last a tiny bit longerThan the aa amazon basics…
The batteries did not last at all. At first …
The batteries did not last at all. At first I thought maybe I didn’t change them and that’s why they were dead but my friend confirmed what I thought and that was I did change…
No charge in any of the batteries!!!
16 of the 20 batteries had 0 charge when tested. 4 had 13%. By the time I needed them the return date had past. I won’t be buying from this store again!

These batteries are terrible. 1⁄3 of them failed is less than a year. Without being used, their voltage dropped to 300 mv while the other batteries stayed at 1.6 v.
