Energizer Alkaline A23 Battery 4 5 10 10
Engergizer A23 battery of no assurance hi, I am from Kuala Lumpur, Malaysia. Last year, I complained on A27 battery. Now, even the A23 failed. Last month, my daughter in Malaysia was caught with her bad performing car alarm remote controller. After trying 15 minutes at the outdoor open carpark, thanks God, at least it worked for once to bring her home from 20 over km away. That Energizer battery in the remote controller was only installed bought and intalled for few months. Later when I tested, found the voltage was less than 7 volts for a 12 volt battery. I then tested the voltage of a GP battery and used it. When I looked at the packing, GP packing shows the expiry date but not my other Energizer battery. Beware, when we buy battery. April 21, 2013
Dont buy the A23 battery My garage door opener remotes operate off of one A23 battery. I should have learned my lesson by now on buying the Energizer brand A23. My past experiences are these batteries are weak even if they have a good date on them. I usually have to be very close to the garage door to get them to open the door. I thought I would try it one more time so this evening I bought another 2pk of A23's. I came home and immediately installed the battery in to a remote. Guess what, It's dead. I checked to make sure I had it installed the correct way and it was correct. I checked my contacts and they also are fine. I took out the battery and put it back in a few more times and still nothing. I put in the other new battery and it works. So with buying the 2 pk, only one battery is working and I once again have spent my money on a product that I knew I should not have bought. These A23 batteries in my opinion are a total waste of money. Every other size of Energizer battery I have used have been excellent but not the A23. December 12, 2012
Love to find rechargeable with charging adapter I have the alkaline A23. I have replaced 98% of my household batteries to rechargeable (better value & greener) but am having trouble finding this one. It appears I would also need to purchase a charging adapter for this size but would consider it, depending on cost. This battery originally came with my ceiling fan remote control and lasted maybe 2 years. September 24, 2012
Got laundered. my husband left his key fob in his pants before putting them in the laundry basket. Not only did the fob go through the complete wash cycle but it also went through the dryer! I couldn't believe it, but it still worked and the only reason why I can think of is because it had an energizer battery in it! Performance rating? How about an A+++ June 13, 2012
Garage Door These batteries have an extremely long life. I use them in my outdoor garage door opener and the batteries last for 5 years between changing them. May 30, 2012
LOOOOOOONNNGGG Life Battery! When the Energizer bunny says it keeps going and going and going, that's not just a commercial catch phrase. Recently I purchased a twin pack of A23 batteries for a ceiling fan remote control device, only to discover the switch had inadvertantly been turned off, and the original battery was fine! That got me thinking, and I realized that battery had been going and going and going for almost 8 years! That's real value for a battery that cost less than $2, but if it ever does stop working, I've got 2 replacements ready to hop into action! May 3, 2012
Won't let me down when needed Tornado's hit our area, and power was lost for a brief time. The "Bunny" came thru for us when we needed the batteries the most. We keep all sizes of the batteries for emergency. They have never let us down yet. thanks May 1, 2012
good product that does the job for a long time good product but had to distinguish from the competition May 1, 2012

Answer: 
I've found several of these batteries are only providing around 8 volts instead of new fresh out of the package. At around 6 volts, the typical garage door opener will stop functioning. Sounds like your batteries were no where near 12 volts when you opened the package.

I've bought several dual-packs at Walmarts in the area. Fresh out of the pack they registered around 8.1 volts. My garage door opener fails to function when the voltage reaches around 6 volts. That doesn't leave much battery life. What is an acceptable voltage for a new battery? Why doesn't the dual-pack show a manufacturing or use by date?

Answer: 
I've used that same battery (A23) for my ceiling fan remote control. I don't know why they don't show an expiration date, but I've been using the same battery now for almost 8 years without a hitch, so I'm thinking maybe between the 8.1 and the 6 volt readings you may still have a lot of life left in those batteries.

Answer: 
Thank you for your question. These batteries are designed to register at 12V when they are new. I have asked a member of our customer support team to contact you via email to get you batteries that have the intended lifespan and determine why these batteries aren't measuring at the correct voltage.

While distribution varies by account, our records indicate that Walmart, The Home Depot and Lowe's all carry the A23 battery from Energizer. Hopefully, you have one or more of those retailers in the Mequite area. Otherwise, this product can be found online as well.

Max Amp. that I can drain?

I want to use this battery in my project. I have a camera that drains 150mA at 12Vdc. And my circuit will drain appr. 200mA. How can I use this battery in my circuit?

I.e. Is connecting 4 of them in parallel a solution? If yes, what would be the battery life?

What is the internal resistance of the battery?

Answers

Answer: 
We spoke to our technology team and here is their recommendation for your particular needs.

An A23 battery cannot handle a 150 mA drain rate required by this application. After reviewing the discharge curve for an A23 battery under a 75 mA drain shows service less than a minute. A 150 mA drain on an A23 battery would pull the voltage very low within seconds. Even multiple A23 batteries in parallel would probably not provide satisfactory service.

For a 150 mA drain, eight E96 AAAA batteries in series would be an option worth considering. http://data.energizer.com/PDFs/E96.pdf For longer runtimes, eight AAA or eight AA batteries in series may be needed.
