I've been replacing lots of batteries on TPMS sensors for folks, and it has always been a little bit of a struggle to get the tabs on the ones I was getting from Digikey to line up and solder on correctly. So I ordered ones with a different type of tab, and I'm happy to report that they fit and work much better. Once you clean all the solder out of the holes, you can now get stem on the tab to go through the hole and make a good mechanical connection prior to soldering by hooking the tab through the hole. You couldn't do this with the P668-ND ones posted about on here, so I think these are a better choice.
The battery is the identical Panasonic, the only difference is the tabs. The Digikey part number for these are P660-ND
