VOLTCRAFT VC-16107975 A23 Alkaline Battery 12V 50mAh, 4-Pack

Unlike standard 12V batteries that often fail under intermittent high-drain pulses, the VOLTCRAFT VC-16107975 A23 alkaline cell delivers stable voltage for remote controls, key fobs, and security sensors. This 4-pack ensures you always have a spare on hand, while the mercury-, cadmium-, and lead-free construction keeps disposal simple and safe.

Highlights

• 12V nominal voltage from a single compact A23 cell
• 50mAh capacity tuned for low-drain, long-life applications
• Alkaline manganese chemistry for reliable performance
• Mercury-, cadmium-, and lead-free formulation
• Blister pack of 4 batteries, ready for immediate use

In daily use

Each battery measures approximately 28.5mm in length and 10.3mm in diameter, fitting standard A23 compartments. The button-top positive terminal and flat negative base ensure secure contact in garage door openers, wireless doorbells, and car alarm remotes. Because the cells are non-rechargeable, they are best suited for devices that require occasional bursts of power rather than continuous high current.
