EnergizerA23 Battery, 12 Volt - 4 Batteries

Q: What is the expiration date on pkg?

Mine came as 2x 2-packs, dated 03/2016 and 03/2017.

Q: what is the length of this battery? i need it ofr a hunter remote part G1241 which has an opening too short for a triple A

if your device can accept an A23 size battery, then this is the one you need. 12 volt alkaline. Try it! You can always return it if it isn't correct. Worth a $5 investment!

Q: does anyone know the ah amp hour of these batteries

These batteries will provide 55 mah if discharged to 6 volts provided a 22K ohm load at 21 degrees celcius.

Q: What is the difference between the A23S and the A23?

Probably nothing! It might be a performance or length of setvic, but they both fit a device that needs these batteries. As always, if theyvare not what you need, Anazon's return policy allows you to return them for a refund to your credit card. BTW, stay away from the generics and purchase the brand. In my anti bark collar, the generics lasted no more than a month; the Energizers last well into 2 months! Good luck!
