Copper Battery Terminal Clamp – Car Storage Battery Pile Head, Pure Copper Galvanized, Model YD264
Copper Battery Terminal Clamp for Car Batteries – Model YD264 Pile Head Clip
This copper battery terminal clamp is the part that joins your car's battery cables to the battery post, sometimes called a battery pile head or battery clip. The supplier lists it as model YD264, describes the metal as pure copper with a galvanized finish, and gives a weight of 135 g. Easy Life Markets offers it in two options, shown in the variant selector as "Red Black" and "SET1".
A terminal clamp looks like a minor part, but every amp the starter motor draws has to pass through it. When the clamp is corroded, cracked or stretched, the connection gets poor, and a healthy battery starts behaving like a flat one. Swapping the clamp is one of the cheaper electrical repairs you can do on a car. For background on post types and sizes, see the battery terminal article.
What Is in the Bag

How the Clamp Is Built
Everything in this section comes from the product photos. Each clamp has a round ring that drops over the battery post, with a pinch bolt and a locking nut at the split to draw the ring tight. Beside the ring is a flat pressure plate held down by three threaded studs with nuts. Cable ends sit under that plate and are clamped when the nuts are tightened, which gives you room for the main cable and extra feeds such as an accessory or charging lead. The red-collared clamp is stamped with a plus sign. The metal has a bright silver-coloured plated finish, and the plastic collar covers part of the ring.
Will It Suit Your Battery?
The ring style shown is the kind used on round, tapered top posts, which is what most car batteries have. Since no dimensions are published, check these points first:
- Look at your battery posts. This style is for round posts on top of the battery. Side-terminal batteries with threaded holes, and small batteries with flat tabs, use a different connector.
- Remember the two posts differ. On standard top-post batteries the positive post is slightly thicker than the negative, so a clamp made for one polarity may not tighten properly on the other.
- Compare with your old clamp. Hold the photos against the clamp on your car and check that your cable ends can be bolted under a plate.
- Check the space. The three-stud plate sits to the side of the ring, so make sure the battery tray, cover or hold-down leaves room for it.
When a Terminal Clamp Is Due for Replacement
- White, green or blue crust that returns soon after cleaning
- A clamp that will not tighten and can still be twisted on the post by hand
- Cracks in the ring or a stripped pinch bolt
- Slow cranking or a single click, even though the battery tests good
- Lights that flicker or dim when you wiggle the battery cable
- A clamp that feels hot after starting the engine
A weak battery or a failing starter can produce the same symptoms, so test the battery before you blame the clamp.
Fitting Tips
- Switch the ignition off. Disconnect the negative cable first, then the positive.
- Keep spanners away from both posts at once. A battery can deliver a very high current through a tool.
- Clean the posts with a wire brush or post cleaner until the lead is bright.
- Cut back any cable that is green or brittle under the insulation and fit sound cable ends under the plate.
- Push the clamp fully down the post before tightening. Tighten until it cannot be turned by hand, and no further.
- Reconnect the positive side first and the negative last.
Wear eye protection and gloves around a battery. If you are unsure about vehicle wiring, have the work done by a qualified auto electrician.
Keeping the Connection Clean
Look at the terminals whenever you check the oil. A thin smear of petroleum jelly or terminal grease over the finished connection helps keep moisture and acid vapour away. Heavy corrosion on one post only can point to overcharging or a leaking post seal, so have the charging voltage checked if it keeps coming back. Re-check the nuts after the first week of driving.
Who Buys This Clamp
It suits owners replacing a corroded or cracked terminal, people adding an extra feed for accessories at the battery, and workshops that keep spare terminals on the shelf. It is a general-purpose part and is not listed for any particular vehicle model.
Common Questions
Is it for the positive or the negative post? The photos show a red clamp marked with a plus sign and a black one. Tell us which you need if the variant name does not make it clear.
Is it a genuine part of a vehicle maker? No. It is an unbranded aftermarket terminal sold under the supplier's model number YD264.
Does it come with cable? No cable is listed in the packing list.
