## Questions & Answers

**Q: Are these 23ae batteries? Needed for Minke ceiling fan remote**
A: A23 battery is also known as 23A, 23AE, GP23A, V23GA, LRV08, 8LR932, 8LR23, MN21, L1028 or ANSI-1181A

**Q: looking for battery dated at least 2022 . What is the expiration date on these batteries ?**
A: I just received my Duracell 4 pack. They do not list and expiration date. They list a "Best Before" date. My  4 pack was dated March 2025. Voltage each of the individual batteries as measured w/ volt meter: 12.76;  12.78;  12.79;  12.80.  
That is good voltage.

**Q: Can i use this to start my truck?**
A: This battery has a maximum current output of 0.05 Amps and a car takes about 200 Amps to crank. That means it would take 4,000 of these batteries in parallel to start a car. I don't think you want to do that.

**Q: Are these batteries really 3.5 inches long?**
A: They are exactly 1.125" (1 1/8") long.
