ATTE ADD-AKU50 Battery Connection Cable 50cm 16mm² Ring Terminals M8 Red

When a UPS technician needs to replace a corroded battery interconnect in a server room, they reach for a cable that can handle high current without heating up. The ATTE ADD-AKU50 is that cable: a 50 cm red battery connection lead with M8 ring terminals on both ends, built from 16 mm² electrolytic copper strands. It's the kind of part that keeps DC power flowing in alarm panels, solar battery banks, and automotive auxiliary systems.

Key specifications

• Cable length: 50 cm (0.5 m)
• Conductor cross-section: 16 mm² multi-stranded electrolytic copper
• Connector type: M8 ring terminals on both ends (8 mm hole diameter)
• Insulation: PVC jacket, red colour
• Rated voltage: Up to 750 V DC
• Maximum current: 100 A
• Operating temperature range: -30°C to +70°C
• Number of conductors: 1

Why choose it

This cable is not a generic jumper wire. The 16 mm² cross-section and high-purity copper conductor minimise voltage drop, which is critical for battery banks where every millivolt counts. The M8 ring terminals are crimped securely and fit standard battery posts, bus bars, and inverter terminals. The red PVC jacket is flame-retardant and resistant to oils and mild acids, so it holds up in engine compartments and equipment racks alike.

Ideal use cases

• Connecting batteries in series or parallel for UPS and solar storage systems
• Replacing worn battery cables in alarm panels, emergency lighting, and access control
• Automotive and marine auxiliary power wiring (winches, inverters, second batteries)
• DC power distribution in industrial control cabinets

Good to know

The cable is supplied as a single piece. For higher current applications, consider doubling up cables or using a larger cross-section. Always torque M8 nuts to the battery manufacturer's specification (typically 8–10 Nm) to ensure a reliable connection without damaging the terminal.
