This pair of 75 mm crocodile alligator clips is rated 35 A and PVC-insulated in red and black, designed for battery testing, automotive jumper leads, and bench-power test probes. The serrated jaws bite onto battery posts, terminal lugs, or bare conductors and the plastic shroud insulates your fingers from the spring contact during use.
Product Description
This is a matched set of crocodile (alligator) clips, one red and one black, supplied with PVC insulation boots already fitted to the jaws. They are 75 mm in overall length, rated for 35 A continuous current, and built with a metal body, a steel spring, and serrated jaws that grip battery terminals, busbars, lug posts, or bare wire ends. The most common use is making temporary electrical connections during car or RV battery testing, motorcycle and lawn-mower battery checks, or bench-supply testing where you need to attach a probe lead quickly without screwing it down.
The PVC boot is a separate part that slides over the rear of the clip and isolates the rear of the spring contact from the user's hand — important when working near a high-current source like a 12 V vehicle battery, where a slip can short across body parts and cause an arc burn. Red is conventionally positive and black is conventionally negative; respect that convention when wiring jumper leads to avoid reverse-polarity damage.
Key Benefits
- 35 A continuous current rating handles 12 V vehicle battery testing and small jumper-lead duty
- 75 mm jaw length provides strong bite on battery posts and terminal lugs
- PVC insulating boots reduce the risk of accidental short across the spring contact
- Red/black coding eliminates polarity guesswork on jumper and test leads
- Serrated tooth pattern grips bare conductor, screw heads, and round terminals equally well
Key Features
The defining feature is the combination of jaw size and current rating. At 75 mm length and 35 A, this clip sits in the "automotive battery test" sweet spot — small enough to bite onto a motorcycle battery post or a bench-supply binding post, large enough to clamp over a car battery terminal lug. Below 35 A you usually only need 50 mm "electronics" clips; above 35 A you start looking at 50 A or 100 A jumper-cable clamps. The PVC insulator is a soft moulded boot rather than rigid plastic, so it stays in place under repeated use and does not crack at low temperatures.

What's Included
- 1 x red 75 mm alligator clip with PVC boot
- 1 x black 75 mm alligator clip with PVC boot
Cable not included. Attach using solder, crimp lugs, or screw terminals depending on the rear connection style of the clip.
Compatibility & Applications
This pair is suitable for any 12 V or low-voltage DC circuit where a temporary mechanical connection is needed and the load is below 35 A continuous. Typical applications include:
- Car, RV, caravan, and van battery testing
- Motorcycle, scooter, and lawn-mower battery checks
- Bench power supply test leads
- Battery charger output clamps for hobby and small-engine batteries
- Multimeter and oscilloscope probe lead extensions
Not suitable for: mains AC connections (the boot is not rated for line voltage), continuous high-current loads above 35 A (jaw heating will exceed the boot's safe temperature), or permanent installations where a screwed terminal would be more appropriate.

Frequently Asked Questions
What does the 35 A rating actually allow me to do?
35 A continuous covers virtually all 12 V automotive battery testing duties — cranking current is far higher than this for a few seconds during a real start, but for the test loads of a multimeter, a battery tester, or a small bench supply running an accessory, 35 A is plenty. For full jumper-cable duty (assisting another vehicle to start), you need 100 A or 200 A clamps, not these.
How do I attach a wire to the clip?
The rear of the clip has either a solder tab or a small screw terminal, depending on the production batch. For solder tabs, tin the wire end and solder it to the tab; for screw terminals, strip about 5 mm and clamp under the screw. Cover the resulting joint by sliding the included PVC boot forward.
Can I use them on a 24 V or 48 V system?
Mechanically yes, but the PVC boot is sized for incidental contact protection at low DC voltages — 12 V and 24 V are within normal use. At 48 V you should treat any exposed metal as a shock hazard and avoid bridging both clips simultaneously with bare hands.
How fast does shipping take?
Orders are dispatched from regional fulfillment partners in North America, Europe, and Asia. Typical delivery is 5 to 15 business days depending on destination country, with tracked shipping included. Specific timelines per destination are listed in the Shipping Policy.
How do these alligator clips compare to others in their category?
Within the alligator-clip category, the meaningful comparison points are jaw length, current rating, and insulator quality. This product uses 75 mm jaws, a 35 A rating, and a moulded PVC boot — the configuration that fits the largest installed base of automotive and bench-power test applications and drives the lowest return rate within our small-electronics category.
