Battery Details.

Don't confuse this with the PX32 as that is also called a "164".

Suggested replacement for the 164 mercury based battery that is no longer available. The physical dimensions are the same but the 164 was 1.35 volts.

Although .5 mm thinner than an LR66 I have used these in place of an LR66 with a small piece of folded paper as packing on the back (the watch had a side contact for positive).
