Description
This is a single silver oxide coin cell from Energizer's Specialty range, marked 377/376 on its face so that it answers to either of those two numbers. Silver oxide is the chemistry small round cells use when a device needs a voltage that stays put: it holds close to its nominal 1.55V for most of its working life instead of drifting down steadily, which is why quartz watch movements keep good time right up to the point the cell stops. The casing is bare metal, with a raised cross marking the positive face.
Coin cells are bought by their number rather than by brand, so the reliable method is to take the old cell out and read what is stamped on it. If it reads 377 or 376, or your instruction booklet lists either of those, this is the cell that goes back in. Watches are the usual home for this size, though the same numbers turn up in small test meters, pointers and compact electronic gadgets. Fit it with the cross facing the contact marked positive, and handle it with a plastic tool or a clean cloth rather than bare fingers, since a cell this small sits in a shallow well and is easy to push in crooked.
Each unit on this listing is one cell, and the price shown is the price of that one cell. Orders start at ten and go up in tens, which suits a repair bench or a workshop drawer better than a single watch change at home. It sits alongside our other Energizer cells, including the 357/303 silver oxide coin cell and alkaline sizes from AAA through to D, so a mixed restock can come from one place.

Frequently Asked
What do the two numbers 377 and 376 mean?
The cell carries both numbers, so it goes into equipment that asks for either one. Read the number off the cell you are taking out and match it before ordering.
How many cells do I receive for the price shown?
One. This listing is priced and sold per cell, and the smallest order is ten cells, going up in multiples of ten after that.
Can this cell be recharged?
No. Silver oxide coin cells of this kind are single use, so once the voltage drops the cell is replaced rather than put on a charger.
Does voltage matter when I swap a cell?
Yes. This one is a 1.55V cell, and a 3V coin cell of a similar diameter is a different chemistry, so match the printed number as well as the size.
