Klamp Quick-Release Battery Terminal - TÜV NORD Certified

What TÜV NORD certification means and the safety tests Klamp passed

The Klamp quick-release battery terminal clamp is independently certified by TÜV NORD (Technischer Überwachungsverein), one of Germany's three major testing, inspection, and certification organisations with over 155 years of history dating back to 1869. Headquartered in Hanover, Germany, TÜV NORD operates across 500+ locations in over 100 countries with more than 15,000 engineers and specialists. Klamp is the only quick-release battery terminal connector of its type to hold this certification.

Safety tests Klamp battery terminals passed for TÜV certification

  • Contact resistance (IEC 60512-2) - measured using the four-wire Kelvin method at milliohm-level accuracy. Klamp's copper alloy internals achieve approximately 0.12 micro-ohms at 10A, with voltage drop not exceeding 3.2mV per terminal point.
  • Current capacity and temperature rise (IEC 60512-5-2) - loaded at rated current up to 800A while temperature is measured at multiple points. The battery terminal connector must not exceed safe thermal limits under sustained load.
  • Dielectric strength (IEC 61984 Section 7.3.12) - high-voltage applied between conducting parts and the polypropylene housing to verify insulation integrity under overvoltage conditions.
  • Lifecycle durability (IEC 60512-13-2) - the standard requires up to 5,000 insertion-withdrawal cycles. Klamp has been tested to over 20,000 function cycles - four times the standard requirement for battery terminal connectors.
  • Vibration resistance (IEC 60512-6-4 / IEC 60512-6-5) - sinusoidal and random vibration stress testing simulating transportation, installation, and operational conditions in vehicles, boats, and 4WDs. Contact resistance is re-measured before and after to verify zero degradation.
  • Mechanical strength (IEC 61984 Section 6.18) - impact and stress testing on the connector body, terminals, and cable clamp retention under pull and twist forces.
  • Salt spray corrosion (IEC 60068-2-11) - exposed to atomised 5% sodium chloride fog for extended durations (up to 1,000+ hours) to evaluate the quality and uniformity of Klamp's 12-micron tin plating and detect any coating defects in the battery terminal.
  • Cyclic salt mist (IEC 60068-2-52) - a more aggressive multi-phase test cycling through salt fog, damp humidity, and dry conditions to simulate real-world marine and under-bonnet environments.
  • Thermal shock (IEC 60512-11-4) - rapidly moved between low and high temperature chambers with 45-minute dwells per cycle across multiple cycles to test resistance to thermal expansion and contraction without degradation.
  • Heat aging (ISO 6722) - extended exposure to elevated temperatures to verify long-term material stability of the brass, polypropylene, and tin plating used in the battery clamp.
  • Low-temperature testing - verifies mechanical integrity and flexibility in cold conditions, critical for cold-start applications in cars, 4WDs, and marine vehicles.
  • Tin plating inspection - thickness measurement (12 microns) and adhesion testing of the plating to the copper-zinc alloy substrate used in Klamp battery terminals.
  • Stainless steel passivation (DIN ISO 4042) - all 316-grade marine stainless steel fasteners checked for proper passivation to ensure corrosion resistance in harsh automotive and marine environments.

Beyond product testing, TÜV NORD conducts on-site inspections of the ISO 9001 certified manufacturing facility (OJOP Sweden AB, Eskilstuna, Sweden) where Klamp battery terminals are produced:

  • Process control methods, capability studies, and statistical quality techniques
  • Calibration and control of all measuring and test equipment
  • In-process inspection and sampling plans at every production stage
  • Non-conforming product identification, segregation, and handling procedures
  • Ongoing surveillance inspections conducted multiple times per year to verify that currently manufactured battery terminals match the originally certified specification

Certificate Registration No. 44 786 150277-001 · Issued by TÜV NORD CERT GmbH, Essen, Germany · Product: Battery connector, model Quick Power · Klamp is the only quick-release battery terminal of its type to hold TÜV certification. Used in Daimler, Unimog, and Volvo military vehicles.

What makes these different from standard quick release terminals?

The Klamp Marine uses 12-micron tin-plated brass instead of raw brass. Tin plating is the marine industry standard for resisting saltwater corrosion, humidity, and oxidation, making these ideal for boats, jet skis, and coastal storage.
Can I use these instead of a battery isolator switch?

Yes. The Klamp gives you the same disconnect outcome as an isolator switch, cutting power to prevent parasitic drain, without installing a bulky panel switch, drilling, or running extra wiring. Just lift to disconnect.
Will they fit my boat/caravan battery?

The Klamp Marine fits all standard SAE and DIN battery posts. For JIS (Japanese-standard, thinner) posts common on some imported engines, add our JIS conversion sleeves at checkout.
What is TÜV certification?

TÜV certification is a globally recognised standard for safety and quality, issued by independent German testing organisations.

Our clamps have been independently tested for:

  • Up to 800A current handling (cranking loads)
  • Vibration resistance (to maintain a secure connection while driving)
  • Repeated use durability (20,000 clamp/unclamp cycles)
  • Thermal performance (heat and cold conditions)

This ensures they deliver a safe, secure, and reliable connection in real-world conditions.
Can I still jump start with these installed?

Yes. Lift the Klamp halfway while it stays connected, then clip your jumper leads on as normal.
What if I don't like them?

We offer a 30-day return policy, no questions asked. If it's not right for your setup, just reach out and we'll sort it. Every Klamp also comes with a 1-year product warranty covering defects in materials and workmanship.
Are they suitable for deep-cycle and dual-battery setups?

Absolutely, they work on starter, deep-cycle, and auxiliary batteries, making them ideal for dual-battery and solar systems in caravans, motorhomes, and 4WDs.

Enjoy 30 days of risk-free returns on all purchases.

Frequently Asked Questions

Yes. Klamp fits all SAE and DIN standard battery posts, which covers the vast majority of marine batteries including starting batteries, deep-cycle batteries, and dual-purpose batteries used in boats, jet skis, and PWCs. Not sure what type you have? Send us a photo at hello@klast.com.au and we'll confirm within a few hours.

Yes. Klamp works with any 12V lead-acid, AGM, or deep-cycle battery with standard round top posts. This includes popular marine battery brands like Century, Optima, Exide, and SuperCharge. It's ideal for trolling motor batteries, house batteries, and starter batteries on boats.

Boats, tinnies, jet skis, PWCs, pontoons, kayak trolling motors, yacht house banks, fishing boats, ski boats, wakeboard boats, and any marine vessel or equipment that uses a standard 12V battery with round top posts. Klamp is also used on caravans, camper trailers, and 4WDs for those who tow.

Klamp accommodates three wire size ranges: 15–25mm², 20–40mm², and 40–70mm². This covers everything from small trolling motor wiring through to heavy-duty marine starter cables and high-draw winch systems.

Klamp measures 67mm × 51mm × 26mm when closed, and 68mm tall when in the release position. This fits comfortably inside most standard marine battery boxes and battery trays. If you have a particularly tight setup, measure 68mm of clearance above your battery posts before purchasing.

Yes. Klamp works on any standard battery post. If you're running a dual battery system (common on fishing boats with house and starter batteries), you'll need one pair per battery (two pairs total). Perfect for quickly isolating individual batteries.

Absolutely. Klamp is built from marine-grade stainless steel 316 and copper alloy — the same materials used in professional marine hardware. The tin-plated marine variant provides additional corrosion protection specifically designed for saltwater environments. Klamp has passed over 1,000 hours of salt spray corrosion testing (IEC 60068-2-11).

Place the clamp over the battery post, compress to lock, power's on. Lift to release, power's off. No spanners, no tools, no fumbling in tight engine bays or wet conditions. The entire process takes about 5 seconds — ideal for quick battery isolation before trailering or storage.

Yes. Klamp is rated safely up to 800A, built from copper alloy and marine-grade stainless steel 316 — the same materials used in industrial and military applications. It supports wire sizes from 15mm² up to 70mm², which handles everything from trolling motors to high-draw winches and starter motors. Klamp is TÜV NORD certified and is used in Daimler, Unimog, and Volvo military vehicles.

Klamp is the genuine OJOP Quick Power connector, designed and manufactured in Sweden from solid 1.6mm brass, copper alloy, and stainless steel 316 in an ISO 9001 certified factory. Cheap marine terminal alternatives ($3–$15) are unbranded copies made from thin painted steel and ABS plastic that corrode rapidly in marine environments. OJOP tested several fakes and they failed after as few as 11 uses. Klamp has been tested to over 20,000 function cycles.

Yes. Klamp is specifically designed with built-in jumper cable and charger access. Lift the lever to the release position and it exposes the brass terminal post, giving you full access to attach jumper leads, a portable jump starter, or a battery charger — without removing anything.

Yes. Many boaties use Klamp as a quick-access master kill switch for safety, anti-theft, or to prevent battery drain during storage and trailering. Lifting the release completely isolates the battery from the vessel's electrical system. It's faster and more convenient than a traditional rotary battery switch for casual use.

Most marine electronics (fish finders, chart plotters, VHF radios) store settings in internal memory and won't lose data when the battery is disconnected. If your boat has an onboard computer or stereo with volatile memory, a small memory saver can maintain settings during disconnection.

The outer shell is polypropylene (impact-resistant, UV-stable plastic). The internal clamp mechanism is copper alloy for maximum conductivity. All fasteners are marine-grade stainless steel 316 — the same grade used in boat fittings, rigging, and marine hardware. These materials are specifically chosen for durability in harsh marine conditions — salt spray, humidity, UV exposure, and temperature extremes.

Klamp is manufactured by OJOP, a Swedish engineering company operating since 1922. They produce over 250,000 Quick Power battery connectors per year, exported to more than 50 countries. The Quick Power connector is used by marine OEMs and military vehicle manufacturers worldwide. Klast is the authorised Australian distributor.

Installation is a one-time job. You'll need wire cutters to remove your old marine terminals, a wire stripper to expose about 10–12mm of clean copper, and a Phillips-head screwdriver to secure your cables into the clamp housing. After that, connecting and disconnecting your boat battery is completely tool-free, for life.

About 2–5 minutes per terminal. Cut off your old terminals, strip the wire, slide it into the Klamp housing, and tighten with a screwdriver. Full step-by-step instructions with photos are available on our installation guide page.

Yes, you'll cut off your old terminal connectors and strip the cable end to expose clean copper wire. This is a permanent upgrade, not a clip-on accessory. The result is a cleaner, more secure, and more reliable connection than standard marine crimp or bolt-on terminals.

Most boat owners install Klamp themselves in under 5 minutes with basic hand tools. No electrical knowledge is needed — just follow our installation guide. If you'd prefer professional installation, any marine electrician can do it quickly and cheaply.

Klamp comes as a colour-coded pair — red for positive (+) and black for negative (−). Always connect positive first when installing. Always disconnect negative first when removing. This is standard practice for all marine battery work.

Yes. Klamp works with both standard copper and tinned marine-grade cable. The bolt-in connection secures the wire firmly regardless of coating. For best results, strip enough insulation to expose 10–12mm of wire and ensure a snug fit in the housing.

Klamp supports wire sizes from 15mm² up to 70mm², which covers the vast majority of marine wiring from trolling motors through to heavy-duty starter cables. If your cables fall outside this range (very rare on recreational vessels), contact us and we'll help you find the right solution.
