The 7 Best A23 Batteries
We spent 24 hours on research, videography, and editing, to review the top choices for this wiki. You've probably got a drawerful of AA and AAA batteries at home, maybe with some Cs and Ds thrown in there from the '90s. But when your garage door opener or key fob remote stops working, you'll need a new set of A23 batteries, which, while you may not have heard of them before, are actually quite common and useful for this exact purpose. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best a23 battery on Amazon.
