Sorry Energizer, but your client care is pitiful, and you are taking money from an unsuspecting public by continuing to sell these cells. In the end, I switched all our battery purchases to Duracell Ultimate.Īs for the $70 in coupons, I let them expire. However, despite many promises, they never follow up with any conclusive response. 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. The batteries have a very long storage time and can be used in very cold weather.These Energizer batteries are made out of lithium. This battery is very impressive at high current, but at low loads it is not much better than alkaline batteries (Except it does not leak). The 3A curve starts with a dip, then it raises again, when the battery gets warm.ĭue to the higher voltage, it has more energy than alkaline. Up to 1A the capacity is nearly constant and even at 3A it can deliver energy. I am not that impressed with the 11x longer specification, you must compare to some really bad batteries for this to be true. Notice that the unloaded voltage for lithium batteries is 1.8 volt. Typical IR: 90 to 160 milliohms (depending on method).Max Discharge: 3.0 Amps Continuous (single battery only) 5.0 Amps Pulse (2 sec on / 8 sec off).Typical Volume: 8.0 cubic centimeters (0.5 cubic inch).Chemical System: Lithium/Iron Disulfide (Li/FeS2). ![]()
