Looks like a Molex connector but I cannot find what type. The closest I've found have the 'D' and square prongs in the wrong configuration. Does anyone know what type/model connector this is? (From a battery charger for a lawn mower)

This looks like a match. Thanks! 😀

Used to see these on rc car batteries all the time

I had a poke around but couldn’t find an exact match. At face value it does appear to be a molex variant, though.

Perhaps you might have some luck thumbing through the molex catalog: https://www.molex.com/en-us/products/connectors/wire-to-wire-connectors

Tamiya ! They suck and they melt. Don't use them. Dean's are far better

I think I have the same one on my ancient Kyosho RC car for hooking up the battery.

Some would call it .... Tim.

Cut the cord. Install connector of choice. Problem solved.

Whether or not it's an official name or not, that's definitely the kind that's called a tamiya connector in the RC world. Tamiya is a company that's a long standing favorite in that hobby.

It wouldn't surprise me to see one on a battery charger at all. I know plenty of RC enthusiasts that will use their preferred connector for anything they run across that needs such a thing

That's interesting, I've been doing RC airplanes for 19ish years and have never seen this connector used. What type of RC do you see this used in?

I only know quads (and barely) so I looked into it and it seems that it's popular for RC cars. Makes sense, ground vehicles take a beating so the clip could be helpful and the extra weight matters less

Pretty sure it’s the Molex connectors I used to use at work. No idea what model it is.

But as others have said, just get a new matching set that meets your current needs (I mean amperes!) and replace. The Molex crimpers are pricey, Btw.
