Description

This is a single silver oxide coin cell from Energizer, marked 397/396 on its face. Those two numbers are alternative codes for the same cell, so a device listed as taking either a 397 or a 396 takes this one. Silver oxide chemistry gives a nominal 1.55V. The cell itself is a plain silver coloured disc with the code and a raised plus sign on the positive face, and the opposite face acting as the negative contact. It is priced and sold per cell, so one unit ordered is one battery.

Silver oxide cells hold a steady voltage across most of their working life rather than tailing away gradually, which is why the chemistry is the usual choice for watches, small calculators and compact precision instruments where a drifting supply would show in the reading. If you are replacing a cell, lift the old one out and read the code stamped on it before ordering. Matching that code matters more than matching the brand, because the diameter, the height and the voltage all have to be right for the cell to sit properly between the contacts.

Ordering is simple once you know what a unit is here. One unit is one cell, and the minimum order is 10 in multiples of 10, so the smallest purchase is 10 separate cells rather than a sealed pack. That suits a household keeping spares in a drawer as much as a workshop restocking a tray. This sits alongside our wider Energizer range, which also covers alkaline coin cells, lithium coin cells and the common AA, AAA, C, D and 9V sizes. Coin cells of this size are a swallowing hazard, so keep them away from small children and take spent cells to a battery recycling point.

Frequently Asked

How many cells do I get for one unit?

One. Each unit is a single 397/396 cell, and the minimum order is 10 units, so the smallest purchase comes to 10 cells.

Is a 397 the same as a 396?

Both codes are marked on this cell, so a device specified for either number takes this battery with nothing else needed.

What voltage does a silver oxide cell give?

Silver oxide chemistry has a nominal 1.55V, and it holds close to that figure for most of its working life rather than falling away slowly.

Which way round does it go in?

The face carrying the code and the plus sign is positive, so it meets the contact marked positive in the holder. The opposite face is negative.

How long will it keep before I use it?

The manufacturer does not state a shelf life for this cell, so we do not quote one. Store spares dry, at room temperature, away from loose metal.
