Why Use the Correct Security Battery?
Alarm and security systems depend on stable voltage and reliable runtime. Using the correct battery type helps reduce false alarms, loss of communication, and unexpected downtime. Lithium cells provide superior performance in high-drain and long-standby devices, while 12V and 6V specialty batteries are designed to match specific equipment requirements.
We carry a broad range of formats so installers, technicians, and end users can find exact replacements for their systems, with options for single units as well as bulk orders.
Frequently Asked Questions
How often should I replace security and alarm batteries?
Most manufacturers recommend checking batteries at least once a year. High-traffic or critical devices may require more frequent replacement, especially if low-battery warnings appear.
Can I replace an alkaline alarm battery with a lithium version?
Only if the device manufacturer approves lithium for that model. Many security devices support lithium for longer runtime, but always follow the product specifications.
Are these batteries suitable for professional installations?
Yes. The batteries in this category are commonly used by alarm installers, integrators, and maintenance teams for both residential and commercial systems.
