Asked Questions

General Questions

What are quick release battery terminals?

Quick release battery terminals replace standard bolt-on clamps, allowing you to disconnect and reconnect your car battery in seconds without any tools. Klamp by KLAST is the genuine OJOP Quick Power connector, designed and manufactured in Sweden from copper alloy, marine-grade stainless steel 316, and polypropylene. It's the only quick-release battery terminal of its type to hold TÜV NORD certification.

Why should I use KLAST terminals instead of normal ones?

Klamp saves time, prevents stripped bolts, and makes disconnecting your battery effortless for maintenance, storage, or track days. Unlike cheap alternatives, Klamp is built from solid 1.6mm brass, copper alloy, and marine-grade stainless steel 316 in an ISO 9001 certified factory in Sweden. It's been tested to over 20,000 function cycles and is TÜV NORD certified — the same connector used in Daimler, Unimog, and Volvo military vehicles.

Installation & Fitment

How do I install KLAST Klamp quick release battery terminals?

Cut off your old terminals, strip 10–12mm of wire insulation, insert the copper wire into the clamp, tighten, and lock the lever onto the battery post. See full install guide here.

Will they fit my car?

Klamp fits all SAE and DIN standard battery posts, which covers the vast majority of cars, 4WDs, trucks, vans, caravans, motorhomes, and boats sold in Australia, the USA, and Europe. It supports wire sizes from 15mm² up to 70mm². If your vehicle is Japanese-made (Honda, Toyota, Subaru, Mazda, Mitsubishi, Nissan, etc.), your battery may use smaller JIS posts — Klamp will fit with the addition of terminal conversion sleeves which we can supply. Not sure? Send us a photo at hello@klast.com.au and we'll confirm.

Do I need to install both positive and negative?

We recommend using both for maximum convenience, but you can install just one if you only want to disconnect the negative side.

Use & Safety

Can I use these on a drift car or race car?

Yes. Many drift and track drivers use Klamp for quick battery disconnects. Klamp is rated safely up to 800A and has been tested to over 20,000 function cycles. However, if you're competing under CAMS, FIA, or other sanctioning bodies, regulations usually require an approved isolator switch for safety. Klamp is not a replacement for a motorsport-mandated isolator, but works perfectly alongside one for daily convenience.

Will disconnecting the battery affect my radio or clock?

For long-term storage disconnection, this isn't a concern — it's actually the point. For brief disconnections under 30 seconds, most modern vehicles will retain their settings. If you plan to disconnect frequently, a small OBD2 memory saver (around $15–$30 from any auto parts store) will keep your ECU, radio presets, and window calibrations intact.

Does it affect car alarms or insurance?

If the battery is disconnected, your alarm won't work. Always check with your insurance provider if that's a concern. For storage and maintenance, most owners simply reconnect when driving.

Product Quality & Warranty

Are these the same as the cheap quick release clips on eBay or AliExpress?

No. 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. The cheap alternatives ($3–$15) are unbranded copies made from thin painted steel and ABS plastic. OJOP tested several fakes and they failed after as few as 11 uses. Klamp has been tested to over 20,000 function cycles and is TÜV NORD certified.

How long do they last?

Klamp has been independently tested to over 20,000 function cycles, which is four times the IEC standard requirement. The internal mechanism is copper alloy, all fasteners are marine-grade stainless steel 316, and the housing is impact-resistant polypropylene — all chosen for durability in harsh conditions including heat, dust, moisture, and salt air. We back every pair with a 1-year replacement warranty.

What's included in the pack?

Each set includes two quick release terminals (positive and negative). JIS sleeves can be purchased separately if needed.

Technical & Certification

What is TÜV NORD certification?

TÜV NORD (Technischer Überwachungsverein) is one of Germany's three major independent testing and certification organisations, with over 155 years of history dating back to 1869. Headquartered in Hanover, Germany, they operate 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

⚡ Electrical Safety Testing
  • 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.
⚙️ Mechanical Durability Testing
  • 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.
🌡️ Environmental & Corrosion Testing
  • 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.
🔬 Material & Coating Verification
  • 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.
🏭 Manufacturing Facility Audit

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
Is Klamp safe for high-amp systems?

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 is far beyond what most vehicles require. Klamp is TÜV NORD certified and is used in Daimler, Unimog, and Volvo military vehicles.

What is Klamp made from?

The outer shell is polypropylene (impact-resistant plastic). The internal clamp mechanism is copper alloy for maximum conductivity. All fasteners are marine-grade stainless steel 316 for corrosion resistance. These materials are chosen for durability in harsh conditions — heat, dust, moisture, and salt air.

Can I still use jumper cables with Klamp installed?

Yes. Klamp is specifically designed with built-in jumper cable access. Lift the lever to the release position and it exposes the brass terminal post, giving you full access to attach jumper cables or a portable jump starter. The connection stays firm in this position — it only fully disconnects when you unclamp it completely.

Can I use Klamp as a kill switch / master disconnect?

Yes. Many customers use Klamp as a quick-access master kill switch for safety, anti-theft, or to prevent battery drain during storage. Lifting the release completely isolates the battery from the vehicle's electrical system.
