Replacement Saft Lithium Batteries

[TurboSam]

I want to replace the Saft lithium thionyl chloride batteries in my wireless door and window sensors (LS14250C and LS14500C), and would like to find a reputable place to buy a reputable brand (preferably Saft since they have worked well for me) that is not selling cheap counterfeits or knockoffs.
 
Any suggestions?

We used Tekcells by the thousands to replace them with no issues.
