4PCS 1000A Alligator Clip Test Lead Electrical Battery Charging Charger Clamp Assortment Connector Kit

These are good heavy-duty clamps. I made a set of jumper cables from 2/0 AWG welding leads. Cranked a 6.0 powerstroke with dead batteries without waiting. No hesitation, cranked soon as connected. The jaws open wide enough to clap fully over the battery terminals.

This was not as heavy duty as led to believe. Not too happy with these.

I used these as replacements for the clamps on my jumper cables. They work BETTER than the original factory clamps. Very pleased with the results. Much sturdier clamp. A bit pricey, but ended up with a superior set of jumper cables. I would do it again, rather than just by another new set of cables, with the inherent flimsy clamps that start losing clamp strength after a couple dozen uses.

These looked pretty good in the ad but when I got them....they were cheap and flimsy. I immediately sent them back. I did order replacements that were first quality AND made in the USA. These are definitely NOT for the time you have to have them work. I like quality tools like most guys and these are definitely NOT that. I gave them two starts because they were shipped promptly (thanks to Prime) and the seller took them back without incident. NOT Recommended!

They are strong clips. I used better connecting lugs than the ones that came with them.

They work, but I thought buying a higher amperage clamp would replace the ones I had worn out. These are no better than the lower amp clamps.

Not a good connection to the cables

clamps work well but part securing cable does secure both wite and insulation and wire slips out after a few uses.
