Pros: Quality battery, lasts a long time, does not leak often
Cons: As good as competitor's batteries in most cases
With three young children in my family we learned quickly to stock up and have LOTS of batteries on hand. My wife maintains a drawer in our diningroom cupboard strictly for batteries. We often buy batteries in bulk for the multitude of electronic devices we use in our home. Most recently, my wife purchased this 12 pack of Energizer AAA batteries.
I love playing around with electronics! It is a hobby of mine. I also believe that most batteries from different manufacturers are pretty much the same. I put my beliefs to the test a while ago. I tried out a variation of the Energizer pink bunny test. Only I used small LED flashlights instead of the pink mechanical bunnies. I placed 3 Duracell AAA batteries in one flashlight, 3 Eveready AAA bateries in a second flashlight, and 3 Energizer AAA batteries in a third flashlight. I placed each of them standing up on their end on the diningroom table and turned them on. I left them like that for several days.
I noticed that ALL of the flashlights gave off equally bright light on the ceiling, where the light was pointed. After the first day, the lights still all gave off equally bright light and they were all still strong. After three days, I came into the dining room one morning and noticed that only the flashlight with the Eveready batteries was still shining, the other two lights died out. The Eveready batteries died out later in the afternoon.
All of the batteries were purchased with 2 months of each other, with the Energizer batteries being the newest. The fresh dates all were by 2014. All of the LED flashlights were the same type. The conditions were pretty much the same for all of the flashlights.
About a year ago, I took apart several dead batteries of various brands in my workshop to see what was inside. All of them were basically the same. There was a hard anode encasing a thin wire surrounded by an electrolyte paste in each battery. They all looked pretty much the same inside.
All in all, I am fairly well convinced that ALL of the various brands of alkaline are pretty much the same. Battery longivity has a lot to do with how the batteries were stored, temperature, humidity, age, etc. The batteries do die down a bit over time, so older batteries will not last as long as new batteries. Also, I believe that dry cell technology has not improved much over the past few years so that any advancement one company finds is bound to trickle over to the other competing companies. My wife shares a different view and she swears Energizer batteries are the best!
I use the Energizer AAA batteries mostly for our various TV/Audio remote control units and for my small LED flashlights. These batteries are made in the USA. They are very good batteries and they do last a while under load. They also do not have the tendacy of leaking out electrolyte, like some of the cheap Chinese batteries do. Once I put some Rayovac batteries in the battery compartments of the memory board on one of my pinball machines. They eventually failed, and when I went to replace them, I found they had leaked out and damaged the battery holder and made a big mess!
I would recommend this 12 pack of Energizer batteries to anyone looking for great batteries in bulk. Usually you can save some money by buying in bulk - this pack cost just under $10 at Walmart. You can buy Energizer batteries in almost any store as they are widely popular. Thanks for reading my review and best wishes for a nice day!
