![]() Fact is, when these cells work, they work well, and I want good cells. It is my suspicion that these cells fail when used in large arrays (meaning anything more than a 4 or 6 gang series config)… but no confirmation from Energizer regarding this theory.ĭespite reporting this to Energizer, my objective was not to get refunds, but to find out why their cells were failing in the field, and getting them to admit there have been production issues with the product. This state had been observed in our lab using a Flir IR Camera. The issue is that a single cell when used in an 8 cell trail cam device will go into an accelerated reaction state where the cell will reach up to 135 degrees centigrade. I have brought up the issue with Energizer and have been issued over $70 in coupons for close to $450 in batteries purchased. I confirm that there is a problem with the Energizer ultimate Lithium AA batteries I have been purchasing since May 2020. Maybe when used in other devices they may perform better. I won’t be wasting my money on these batteries, at least in this clock. Honestly I don’t know when they died, because I’ve been away for the past 2 weeks, so they could have died between 4/17 and 4/30, which is far less than the 2-3 months I get out of other batteries I’ve used in the past. Sadly, today is 4/30/18, and the Ultra Lithium batteries have run out of juice. (In the past, I never actually wrote down the date of installation, but I did with these Ultra Lithium because I was excited not to have to change the batteries as often and wanted to gauge how long they worked to see if it was worth spend the extra money.) ![]() My past experience when using regular energizers or Duracell or Costco Alkaline batteries is that I get approximately 2-3 months of in the clock before it stops working and requires fresh batteries. On I decided to try the Energizer Ultimate Lithium batteries in my clock. I have an Oregon scientific Model BAR338PA LCD/ceiling projection Alarm / wireless outdoor temp / weather info clock which operates on 4 (AA) batteries and also plugs in to the wall outlet (for the projection part only). Manufacturer’s approximate run time on high is listed as 2 hours. ![]() The LED flashlight is set to high at 100 lumens and left on until completely turned off. I used 2 of each type and did a battery drain test on a TerraLUX Lightstar 100 flashlight which takes one AA battery. So how does the Energizer Ultimate Lithium Batteries stand up against the other competitors? I tested it against 3 different rechargeable batteries and 2 different standard batteries. These batteries also have a shelf life of 15 years – which I’ll take their word for it. I don’t have a scale to test their claim, but they do feel lighter when compared with the batteries that I own. Energizer states that these batteries are “33% lighter than ordinary alkaline batteries”. So it’s nice knowing these “bunnies” are born in America. Most of the batteries that I have are either Made in Japan or Germany. ![]() These Energizer Ultimate Lithium Batteries are Made in USA. And the fine print on these batteries show something different from the other batteries that I have. We're leading the journey to a future where Energizer ® has a positive impact on the world.These Energizer batteries are made out of lithium.
