Most CMOS/RTC batteries have a standard connector type, however after exhausting tons of time searching I cannot seem to find the type of connector these use.

It's a 2 pin connector with 1.25mm pitch. It reminds me of a JST type connector however it's not that, and I've also search to see if it was apart of any molex mini series. Pictures for reference:

I'm looking for connector B in this picture, connector A seems to be a JST-SH 1.0mm pitch.

  • \$\begingroup\$ @TonyStewartolderthandirt would you happen to have a model number, part type or anything? I already know they're available somewhere. \$\endgroup\$ – HereNowWhy Jun 11 '18 at 18:28

The 2”wire pair with crimp pin sockets may be easily searched , then compare dwg. Dimensions for polarized tabs and housing then choose mating crimp pin sockets with 2” wires for ease of use.

D-K , Mouser etc have excellent search filters but connectors like this tend to be unique and IP protected for some time for copy protection. So often 2nd sources are rare.

I used to specialize in sourcing hard to get high volume connectors and for 500$ MOQ , AUK connectors in TW did a pretty good job.

Looks like it's a MPN connector from Molex's picoblade series. Still not entirely sure. The Intel NUC board has the connector I'm looking for and the part number is listed as 85205-0200 and the one listed below is slightly different but with same dimensions. Link to an eaglepcb library with a footprint/symbol aswell.
