Description

The 364 is a small silver oxide button cell giving 1.5V, and the card prints its main code as SR621 alongside the alternatives V364, SR60 and SR621W. Those numbers matter more than the name, because watch cells are sold under several codes at once and the one stamped on the cell you are replacing is the one to match. Silver oxide holds a steady voltage for most of its working life rather than sagging gradually, which keeps a quartz movement running at a consistent rate until the cell is close to spent.

Quartz watches are the usual home for a 364, and it is the sort of thing worth keeping in a drawer if you own more than one watch, because a watch that has stopped is far more often a flat cell than a fault. Before you buy, lift the caseback or check the manual and read the code off the old cell. If your watch is water resistant, it is worth having the change done by a jeweller who can reseat the gasket and pressure test the case, since the seal is disturbed every time the back comes off.

One unit of this listing is a single 364 cell on a blister card, so count one per watch you intend to service. The minimum order is 10, sold in multiples of 10, which suits a repair bench, a jeweller's counter or anyone keeping a spares tin topped up. The card is printed with a long life guarantee and with the warning to keep cells out of reach of children, which is worth taking seriously with anything this small. It sits alongside our other Duracell cells, including the 371/370 (SR920) and 376/377 (SR626) silver oxide sizes and lithium coin cells such as the CR2032 and CR2025.

Frequently Asked

How many cells do I get?

One. A single unit of this listing is one 364 cell on its own blister card, and the minimum order is 10 cells, sold in multiples of 10.

My old cell is marked SR621 or V364 rather than 364. Is it the same battery?

Yes. The card lists 364, SR621, V364, SR60 and SR621W as codes for the same cell, so a watch marked with any of those takes this one.

What voltage does it give, and does it stay steady?

It is a 1.5V cell. Silver oxide holds its voltage well through most of its working life, which is why quartz movements tend to keep good time on it until the end.

Does the manufacturer state a shelf life?

No dated figure is printed on this card. It carries a long life guarantee, but no number of years in storage is quoted, so we do not state one here.

How do I work out whether this is the right size for my watch?

Read the code off the old cell, or check the watch manual. Most casebacks are unmarked, and a jeweller can identify the size in a few seconds for you.
