Comments:
These Seiko 3023-24T devices were originally not batteries at all, but miniature capacitors. More recently however, Seiko has upgraded their specification and replaced them with minute rechargeable batteries.

This is a genuine SEIKO KINETIC MOVEMENT capacitor / battery for use in Seiko Kinetic watches.

Consisting of a Panasonic MT 920 with special connector plates, this Seiko part 3023-24T is a replacement capacitor for the following Seiko watch movement calibres:

Pulsar YT57,
Pilsar YT57B,
Pulsar YT58,
Seiko YT57,
Seiko YT57B,
Seiko YT58,
Seiko YT** (all calibres beginning with "YT"),
Seiko 7L22,
Seiko 7L22A,

There are many similar versions of this cell. IF YOU DON'T SEE ONE OF THESE NUMBERS ON YOUR WATCH THEN THIS IS THE WRONG BATTERY FOR YOU.

The calibre is typically inscribed on the back of your watch. For example a watch might have........

220905 - 7L22 - OAJO

inscribed on the back. The calibre, 7L22, is highlighted.

These 3023-24T MT920 with tag are almost exclusively used in Pulsar Kenetic and Seiko Kenetic electronic watches.

The Panasonic MT920 is a button-type titanium carbon lithium rechargeable Li-ion battery that uses lithium titanium oxide as the positive material, carbon as the negative material, and organic electrolyte.
