Frequently Asked Questions

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 has been tested to over 20,000 function cycles and is TÜV NORD certified - the same connector used in Daimler, Unimog, and Volvo military vehicles.

Each pack includes two quick release terminals - one positive and one negative. JIS conversion sleeves for Japanese vehicles can be purchased separately if needed.

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.

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, which we can supply. Contact us and we'll confirm your fitment.

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 (common in 4WDs, caravans, and boats), you'll need one pair per battery - two pairs total.

Yes. Klamp is compatible with lithium iron phosphate (LiFePO4) batteries, AGM, gel, and standard lead-acid - any battery with standard SAE or DIN round top posts. The copper alloy internals provide the low-resistance connection that lithium setups require.

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

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.

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.

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.

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. 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.

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.

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.

The Marine Klamp uses 12-micron tin-plated brass instead of raw brass - the marine industry standard for resisting saltwater corrosion, humidity, and oxidation. Ideal for boats, jet skis, and coastal storage. All other specs (800A rating, 20,000+ cycles, TÜV certification) are identical.

Absolutely. It's built from marine-grade 316 stainless steel and copper alloy, with tin plating that has passed over 1,000 hours of salt-spray corrosion testing (IEC 60068-2-11). This exceeds the requirements for permanent saltwater exposure.

Yes. Many boat owners use Klamp as a quick-access master kill switch - lift to fully isolate the battery before trailering or long-term storage, with no bulky rotary switch to install. It's especially popular on boats, jet skis, and tinnies where space is tight.

Yes. If you're running a starting battery plus a house bank (or twin outboard setup), you'll need one pair per battery - two pairs total. Klamp works on any standard marine battery post.

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. Every pair is backed by a 1-year replacement warranty.

TÜV NORD (Technischer Überwachungsverein) is one of Germany's three major independent testing and certification organisations, with over 155 years of history. Klamp is the only quick-release battery terminal of its type to hold TÜV NORD certification (Certificate No. 44 786 150277-001). The certification covers electrical safety testing (IEC 61984, IEC 60512), mechanical durability testing, environmental and corrosion resistance (IEC 60068), material verification, and ongoing manufacturing facility audits.

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.

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.

Klamp's contact resistance is approximately 0.12 µΩ at 10A, which is negligible and comparable to a well-tightened traditional terminal. The solid copper alloy clamp mechanism ensures maximum conductivity with no measurable voltage drop under normal operating conditions.
