Are you a source for Renata 2 volt lithium batteries?
Yes. We have the R44, R315, R312, R333 (0ld #42), R339 (old #52) R362, R364, R371, R750 which is replaced by the R750. Contact us for pricing. Renata recommends that their 2 volt lithium cells not be tested prior to installation because some tests draw current that will ruin the battery. Use only a high impedance (1-mega-Ohm) voltmeter to test these cells.
