Questions, answered.
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. Not sure what type you have? Send us a photo at hello@klast.com.au and we'll confirm within a few hours.
Japanese-made vehicles (Honda, Toyota, Subaru, Mazda, Mitsubishi, Nissan, etc.) often use slightly smaller JIS battery posts. Klamp will fit with the addition of terminal conversion sleeves. Contact us and we can supply these.
Cars, utes, 4WDs, trucks, vans, caravans, motorhomes, camper trailers, boats, jet skis, ride-on mowers, tractors, and any vehicle or equipment that uses a standard 12V lead-acid, AGM, or deep-cycle battery with round top posts.
Klamp accommodates three wire size ranges: 15–25mm², 20–40mm², and 40–70mm². This covers everything from standard passenger vehicles up to heavy-duty 4WD, commercial, and marine setups.
Klamp measures 67mm × 51mm × 26mm when closed, and 68mm tall when in the release position. This fits comfortably in most standard engine bays, battery boxes, and caravan 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 setup, you'll need one pair per battery (two pairs total).
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. The entire process takes about 5 seconds.
Yes. Klamp is 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. 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. The cheap alternatives 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.
Yes. Klamp is specifically designed with built-in jumper cable access, so you can connect jump leads while the terminal is still attached to the battery. No need to remove anything.
For long-term storage, 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.
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.
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 Australian conditions — heat, dust, moisture, and salt air.
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. Klast is the authorised Australian distributor.
Installation is a one-time job. You'll need wire cutters to remove your old 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, daily use 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 your original bolt-on terminals.
Most customers 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 auto electrician or mechanic 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.
The consumer version uses a bolt-in connection secured with a screwdriver, which is the easiest method for DIY installation. OJOP also manufactures OEM crimp-fit versions for professional or high-volume installations — contact us if you need these.
Klamp supports wire sizes from 15mm² up to 70mm², which covers the vast majority of vehicles. If your cables fall outside this range (very rare), contact us and we'll help you find the right solution.

We offer a 30-day return policy, no questions asked. If Klamp isn't right for your setup, reach out and we'll sort it. Less than 1% of our customers ever ask for a return.
Yes. If you've installed Klamp and it doesn't work for your setup within the first 30 days, contact us and we'll work out a solution. We'd rather you're happy than stuck with something that doesn't suit your vehicle.
Email us at hello@klast.com.au with your order number and a brief reason. We'll provide return instructions and process your refund within 3–5 business days of receiving the product back.
Every Klamp comes with a 1-year product warranty covering defects in materials and workmanship under normal use. This does not cover damage caused by misuse, improper installation, modification, or normal wear and tear.
Contact us with a description and a photo or short video. If it's a manufacturing defect, we'll send a replacement free of charge — we won't make you wait for us to receive the faulty unit before shipping the new one.
Klamp is built from corrosion-resistant materials (copper alloy and stainless steel 316), but performance can vary depending on environmental exposure. If you're using Klamp in a marine or high-salt environment, we recommend the tin-plated marine variant for maximum protection. General corrosion from extreme neglect or chemical exposure is not covered under warranty.
