Energizer Silver Oxide Coin Cell Batteries (370/371)

The 370/371 is a silver oxide coin cell, and we price and sell it one cell at a time rather than in a strip. Both reference numbers are marked on the cell, which is what you want when you are matching a replacement: equipment stamped 370 and equipment stamped 371 take this same cell. Silver oxide is the chemistry used in small precision devices because it holds a steady voltage for most of its working life instead of tailing off slowly, so a watch keeps time rather than running down by degrees. Nominal voltage is 1.55V, and that is the figure to read off the old cell before you order.

Cells in this format sit inside wristwatches, small clocks, calculators and other compact electronics where there is no space for a cylindrical cell. The positive terminal is marked with a plus on the flat face, so the cell is easy to seat the right way round in a caseback or a sprung holder. If you look after several watches, or a workshop drawer of small instruments, buying by the cell lets you stock only the references you actually use. It sits alongside our other Energizer coin cells, including the 357/303 silver oxide cell, the 377/376, the alkaline LR54/189 and the CR2032 lithium.

Every unit here is a single cell, and the price shown is the price of that one cell. The minimum order is 10, in multiples of 10, so the smallest purchase is ten individual cells: handy if you are restocking a repair bench, and worth knowing before you add to the basket. No shelf life figure is stated by the manufacturer for this cell, so we quote none. Coin cells are a swallowing hazard, so keep spares in their packaging and well out of reach of children and pets.

Is the 370 the same cell as the 371?

Yes. This cell carries both reference numbers on its face, so it answers to either code and suits equipment listed under 370 or under 371.

What voltage does this cell give?

It is a 1.55V nominal cell. Silver oxide holds that voltage steadily through most of its working life, which is why it suits watches and small measuring instruments.

How many cells do I actually receive?

One cell per unit, because this listing is priced and sold per cell. The minimum order is 10 cells, bought in multiples of 10.

Can I fit a 3V lithium coin cell instead?

No. A lithium coin cell runs at 3V against this cell's 1.55V, so it is not a substitute and may harm the device.

Which way round does the cell go in?

The flat face carrying the plus symbol is the positive terminal, so seat the cell with that face against the positive contact in the holder.
