DMP 369/4 7.0 Ah 12 VDC Lead-Acid Battery
The DMP 369/4 is a sealed lead-acid battery rated at 7.0 ampere-hours (Ah) and 12 volts DC, purpose-built to provide backup power for access control systems, door controllers, and ancillary security equipment during mains power loss. This battery integrates into DMP-based architectures and related professional security infrastructure where auxiliary energy storage is required without active charging management.
Key Features
- 7.0 Ah Capacity: Supplies 7 amp-hours of energy at 12 VDC — meaning a device drawing 1A will run for approximately 7 hours on full charge, or a 7A load runs for 1 hour. Size your backup runtime based on your connected door controllers, card readers, and strike mechanisms.
- 12 VDC Output: Standard voltage for access control ecosystems, eliminating the need for voltage conversion and simplifying wiring integration into existing DMP panel architectures and compatible security gear.
- Sealed Lead-Acid Chemistry: No active maintenance required — no liquid electrolyte to monitor, no periodic water top-ups. Sit-and-forget reliability in cabinet or enclosure installations where vandalism or accidental spill is a concern.
- Auxiliary Backup Role: Designed as a stationary backup source rather than a primary battery, meaning it sits dormant until AC power fails, then delivers its stored energy to keep access points and monitoring systems alive during the outage window.
- No Built-in Charger: The 369/4 is a standalone battery module — charging is managed by your existing DMP control panel, UPS, or separate charging circuit. Confirm your panel's charge voltage and current are compatible before installation.
- Compact Sealed Form Factor: Enclosed casing is safe for indoor cabinet deployment without ventilation requirements or gas-release concerns, and fits standard battery mounting positions in control enclosures.
Integration & Compatibility
The 369/4 integrates into DMP access control installations as a drop-in replacement or primary backup unit where 12 VDC auxiliary power is required. The 7.0 Ah capacity and sealed construction make it suitable for small-to-medium control panels managing a handful of doors or readers — verify your system's total current draw and desired backup duration to confirm this capacity is sufficient. The battery connects to your DMP panel's charging terminals; ensure polarity and connector type match your installation before ordering.
Sizing Your Backup Duration
Calculate runtime by dividing the 7.0 Ah capacity by your peak system current draw. For example, a door controller drawing 0.5A on backup power will run for 14 hours on a fully charged 369/4. If you need longer runtimes or are powering higher-draw equipment (keypads, release solenoids, strobes), you may need multiple batteries in parallel or a higher-capacity variant — consult your system integrator or DMP documentation to confirm the right configuration for your site.
Frequently Asked Questions
Q: Can I use the DMP 369/4 as a primary power source or only as backup?
A: The 369/4 is designed as a backup power source — it sits idle until mains power fails, then supplies energy to keep critical access control equipment alive. It is not intended as a primary continuous-duty battery.
Q: How long does the 369/4 take to charge?
A: Charge time depends on the charging circuit in your DMP panel or external charger. Consult your panel's technical documentation or contact your integrator for the specific charge profile and time estimate for full recharge.
Q: What is the operating temperature range for the 369/4?
A: Sealed lead-acid batteries typically operate safely between −4°C and 50°C (25°F and 122°F). Confirm your installation environment falls within this range; extreme heat or cold will reduce capacity and lifespan.
Q: Is the 369/4 compatible with all DMP panels?
A: The 12 VDC output is standard across DMP architectures, but battery connectors and charging specifications may vary by panel model. Verify your specific DMP control panel's battery compartment and charging voltage before purchasing.
Q: Can I connect two 369/4 batteries to double my backup runtime?
A: Yes, batteries can be wired in parallel (positive to positive, negative to negative) to increase total Ah capacity and runtime. Your DMP panel's charging circuit must be rated for the increased capacity. Consult your integrator before parallel installation.
Q: What is the shelf life of the DMP 369/4 if unused?
A: Sealed lead-acid batteries gradually self-discharge over time when not in use. Before deploying a new or stored battery, have it charged fully and tested to confirm capacity. Typical shelf life is 6–12 months before significant capacity loss occurs.

The DMP 369/4 is a straightforward workhorse — a sealed 7.0 Ah lead-acid battery for access control backup. It's not flashy, but it's exactly what you need when you're building out a small-to-medium multi-door system and your DMP panel requires auxiliary battery capacity for door strike hold-up during a power event.
Technical Highlights:
- 7.0 Ah at 12 VDC: Delivers roughly 84 watt-hours of stored energy. A typical electric strike consuming 0.8A will run for about 8–9 hours on full charge — long enough to bridge most brief outages and give tenants time to exit or your security team time to respond.
- Sealed Lead-Acid Chemistry: No ventilation holes, no explosive gas venting, no maintenance. Safe to install in a locked cabinet next to your DMP panel without any special HVAC or safety infrastructure.
- 12 VDC Direct Output: Matches DMP's standard auxiliary voltage, so no step-down converters, no efficiency loss, no extra points of failure between the battery terminals and your door controller input.
Deployment Considerations:
- Runtime Math is Critical: Calculate your actual backup load (all door strikes, card readers, backup solenoids) and verify the 7.0 Ah capacity covers your required hold-up window. A single strike at 1.0A draw cuts your runtime to 7 hours; two strikes at 0.5A each do the same. Get the spreadsheet right before you order.
- Charge Circuit Matters: This battery has no on-board charging controller. Your DMP panel must have a compatible charging circuit that recognizes a fully charged battery and stops pushing current into it — otherwise, overcharging and premature failure follow. Verify your panel's charging specs match before installation.
- Temperature Sensitivity: Lead-acid capacity drops in cold environments (winter basement installs will see lower effective Ah). Hot server rooms accelerate aging. If your installation is outside the −4°C to 50°C band or subject to thermal swings, you'll need either a higher-capacity battery or an environment-controlled cabinet.
The 369/4 is your choice for smaller access control clusters — a 4–6 door system, perhaps with a secondary reader and basic keypad. If you're planning a 16+ door installation or a site that demands 24+ hour hold-up after a utility failure, you'll want to discuss battery strings or larger units with your systems integrator. Straightforward product, solid specs, worth the validation effort upfront.
