Altronix BL6 68" Battery Lead Pair 18AWG
The Altronix BL6 is a matched pair of 68-inch battery leads designed to interconnect battery backup systems and power distribution equipment in security infrastructure installations. The BL6 uses 18AWG wire gauge — a practical choice that balances current-carrying capacity with installation flexibility in tight cabinet spaces.
Key Specifications & Benefits
- 68-inch length: Spans typical cabinet depths and nearby external battery enclosures without requiring spliced extensions. Reduces intermediate connection points that can degrade voltage stability under load.
- 18AWG wire gauge: Supports adequate DC current for mid-range UPS systems and battery backup modules without excessive voltage drop over this distance. Verify your system's maximum current draw to confirm this gauge is sufficient — oversizing to 16AWG or 14AWG may be needed for high-current installations.
- Color-coded conductors (red and black): Red identifies positive, black identifies negative. Eliminates polarity guessing during installation and reduces the risk of reversed connections that can damage downstream equipment.
- Matched pair configuration: Both leads are identical length and gauge, ensuring balanced DC power distribution and simplifying inventory management across multiple cabinet builds.
- Lifetime Limited Warranty: Altronix covers defects in materials and workmanship for the lifetime of the product — meaningful for infrastructure components expected to operate passively for years without replacement.
Typical Deployment Scenarios
The BL6 pair is commonly used to connect external battery modules to access control power supplies, UPS systems, and emergency lighting circuits. In a typical access control cabinet, one lead routes from the battery positive terminal to the power distribution module's input; the other completes the negative return. The 68-inch length accommodates battery enclosures positioned below or beside the main cabinet without requiring conduit runs.
For power supplies and backup power systems, proper battery interconnection directly affects failover response time and voltage stability. Undersized wire or loose connections introduce resistance that can trigger nuisance load shedding or delayed system activation during a mains outage.
Integration & Compatibility
The BL6 pair is compatible with any battery backup system or power supply that accepts direct DC input via ring or spade terminal connectors. Verify the terminal style (ring lug, spade, or bare wire) on both your battery module and power supply before ordering — the BL6 itself ships with bare wire ends and requires crimped or soldered terminal connectors to match your equipment's connector specification.
When planning cabinet layouts, account for the 68-inch reach in your cable routing. If your battery enclosure is farther than 68 inches from the power supply input, you will need to run additional gauge-appropriate cable or source a longer lead assembly.
Frequently Asked Questions
Q: Can the BL6 handle my UPS system's maximum discharge current?
A: 18AWG wire is rated for roughly 14–20 amps depending on insulation type and ambient temperature. Check your UPS or battery backup module's maximum discharge current specification. If it exceeds 20 amps, you will need heavier gauge wire (16AWG or 14AWG) to avoid voltage drop and potential thermal stress.
Q: Do the BL6 leads come with connectors or terminal lugs?
A: The BL6 ships with bare wire ends. You must crimp or solder ring lugs, spade terminals, or other connectors to match your battery module and power supply's connection points.
Q: What is the maximum length I can run the BL6 without significant voltage drop?
A: At 68 inches and 18AWG, voltage drop remains negligible for typical UPS discharge currents (under 10 amps). Beyond this length or with higher currents, consider upgrading to 16AWG or 14AWG to maintain system response performance during power failure scenarios.
Q: Is the BL6 suitable for outdoor or high-temperature cabinet installations?
A: The BL6 pair supports standard operating temperatures for most indoor cabinet environments. If your cabinet will be mounted outdoors or exposed to sustained heat above 60°C, confirm the wire insulation rating matches the ambient temperature to prevent insulation degradation.
Q: Does the Lifetime Limited Warranty cover physical damage or incorrect installation?
A: Altronix's Lifetime Limited Warranty covers manufacturing defects. Physical damage from mishandling, environmental exposure, or improper termination is typically not covered — treat the BL6 pair as you would any hardwired component and avoid unnecessary flex or strain during and after installation.

The BL6 is a straightforward but critical component: a 68-inch matched pair of 18AWG leads that bridges battery modules and power distribution in access control and backup power cabinets. The spec sounds humble, but wire gauge and length directly determine voltage stability during failover scenarios. Get this wrong and your system's response time suffers.
Technical Highlights:
- 18AWG wire rating (14–20 amps): Adequate for mid-range UPS discharge without excessive voltage drop at 68 inches. Anything beyond 20 amps at this length requires 16AWG or heavier. That's a hard limit, not a suggestion.
- 68-inch reach: Spans most cabinet-to-external-battery layouts without splicing. Spliced connections introduce resistance; avoid them if possible.
- Color-coded red and black: Prevents reverse polarity — a fault that can trigger cascading failures in downstream power modules. Installation discipline matters here.
Deployment Considerations:
- Verify your system's maximum discharge current against the 18AWG rating. Oversized systems need heavier gauge wire; under-gauging causes voltage sag during mains failure, delaying access control unlock and alarm reporting.
- The BL6 ships with bare wire ends — you must terminate with ring lugs or spade connectors. Crimp quality is critical; poor crimps introduce contact resistance equivalent to under-gauging the wire.
Deploy the BL6 as a matched pair in mid-capacity backup power installations where current draw stays under 15 amps and cabinet-to-battery distance is 68 inches or less. For larger systems or extended runs, specify heavier gauge leads and plan your termination scheme before procurement.
