BBTO 10 Pcs 9v Battery Connector T Type 9v Battery Connector Clip Long Cable Connection Hard Plastic Shell for Student Experiments, DIY Projects, and Electronic Equipment

I used 2 of these to replace defective 9v battery clips inside Fan remote controls. The fan remote that came with a controller as well as a replacement remote for it both had faulty wire connectors going to the 9v battery. I just took the board out and soldered a replacement connect on there from this 10pk here, and wow the remotes now work great. These are very good sturdy battery connectors and wires. Attached is a picture of the replacement battery connectors as they came in a zip lock bag for storage.

This is a solid little connector that doesn't seem nearly as prone to breakage as some of the really cheap junky ones coming out of China. Those always have leads that pull away from the contacts inside the shell and have to be disassembled and soldered back together. I use 9V clips pretty abusively, since I have a lab bench and slapping a 9V battery with a 7805 regulator on some circuit is a fast way to get a floating 5VDC supply for it. So I'm pretty particular about finding clips like this one that will stand up to some punishment.

Use them as part of my UV cure light for hollow resin prints. Works like a charm.

Well the connectors are the correct spacing and size for a 9 v battery. The wires are a good length and tinned nicely for soldering. However, these clip connectors are usually in a somewhat confined space, as in my outdoor garage door opener keypad. That meant, for me to make it work, I had to pry off the top of the plastic cage that covers the back of the connectors. Then I had to snip off the remaining parts of the cage near the connectors. Then I had to tape over the back of the connectors to make sure they were insulated. Now it fit in the keypad case.On new work where one could make sufficient room for the "oversized" connector assembly it wouldn't really be a problem. But on old work be prepared to do some modifying if your cramped for space.

Works perfectly and very good price. And good shipping

The hard plastic around the contacts is better than the old style vinyl.

These are pretty good, better than the flimsy ones you find elsewhere that are difficult to apply and remove from the battery. These battery plugs are made of a sturdy plastic that doesn't bend when manipulated.The only downside is that the leads break easily if you're not careful, I broke them a couple times while crimping on some alligator clips.

Bought these for arduino project and have four main complaints:The wires are twisted strands and hard to solder.The sheath is weak low quality plastic and melts when you’re soldering the wires.The metal snaps are way too tight on standard Duracell batteries. When trying to disconnect it feels like youll rip the battery or connector apart.The plastic housing is loose fitting and feels like it will disassemble unexpectedly.
