DMP 365/4 12 VDC Sealed Lead-Acid Backup Battery
Overview
The DMP 365/4 is a 12 VDC, 9.0 Amp-hour sealed lead-acid battery designed to provide emergency standby power when mains supply fails. Rated at 9.0 Ah, this battery delivers sufficient capacity for extended backup operation in security control panel installations, access control systems, and integrated alarm deployments where auxiliary power during outage is non-negotiable. A 9.0 Ah rating means roughly 4.5 hours of continuous draw at 2 amp load — a standard metric for control panel runtime calculations. The sealed construction eliminates electrolyte maintenance and makes it safe for indoor mounting in equipment racks or cabinets.
Compatibility
The 365/4 is rated for all DMP XT Series and XR Series control panels. Verify your panel voltage requirement matches 12 VDC before installation. The 9.0 Ah capacity suits panels requiring extended backup during mains loss; smaller or larger capacity variants exist within the DMP battery line, so confirm your panel's recommended amp-hour rating in the control panel manual. Connector type and polarity must match your specific panel's battery terminals — do not assume standard size. Contact DMP technical support or your integrator if unsure which battery model your panel accepts.
Installation Notes
Sealed lead-acid batteries require secure mounting to prevent movement during vibration or impact. Ensure connectors are fully seated and corrosion-free before energizing. Store in a dry, temperature-controlled environment — extreme heat or cold reduces effective capacity. Do not expose to freezing conditions during storage. Verify correct polarity (positive/negative) before connecting to the panel to avoid component damage. A dead or discharged battery should be recharged or replaced immediately — do not attempt to use a depleted unit in production.
