12V battery alkaline cell battery A27 Extended Runtime for Specialized Electronics
The 12V Alkaline 27A battery delivers reliable power for compact devices requiring sustained high voltage.
With a typical capacity of 25-35 mAh, it provides 3-5× longer runtime than zinc-carbon equivalents in ultra-low drain applications.
Engineered for intermittent-use electronics, it powers security remotes and sensors for 1-3 years without replacement.
The low self-discharge rate (≤3% annually) ensures 5+ years of shelf life for emergency backups.
