What is an acceptable voltage for a new battery out of the pack?
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?
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.
