Description

This is a blister pack of two Energizer alkaline coin cells, marked LR54/189 on the card. Both of those are names for the same battery: LR54 is the IEC code and 189 is Energizer's own number for it, so a device that calls for either will take this cell. The chemistry is alkaline and the pack gives the nominal voltage as 1.5V. Alkaline is the usual chemistry at this size and it suits low drain devices that sit switched on for months at a time rather than anything that pulls hard current in short bursts.

Coin cells exist wherever a device is too slim to hold a cylindrical battery, which is why they turn up flat against the back of a case or under a small screw down cover. The important thing when you replace one is to buy by the code rather than by eye. Cells of the same diameter can differ in thickness, and the prefix carries the chemistry: an LR code is an alkaline cell at 1.5V, while a CR code is a lithium cell at 3V. The two are not substitutes. Read the marking on the cell you are taking out, or the code printed inside the compartment, and match it exactly.

One unit of this listing is the pack of two, so each one you order puts two cells in your hand. We sell it in multiples of ten, with ten as the minimum order, which suits a workshop drawer or a service kit better than a single replacement. Keep spares in the unopened card so the faces cannot bridge against coins or keys, and keep coin cells well out of reach of children, since swallowing one is a medical emergency. This cell sits alongside our wider Energizer range, from other alkaline coin cells such as LR43/186 and LR44 through to AA, AAA, C, D and 9V.

Frequently Asked

Is LR54 the same cell as 189?

Yes. LR54 is the IEC code and 189 is Energizer's own number for the same battery, so either marking points to this pack.

How do I check which cell my device takes?

Read the code moulded onto the cell you are removing, or the code printed inside the battery compartment, and match it exactly before ordering.

What voltage do these cells give?

The pack gives 1.5V nominal, which is the standard output for an alkaline cell of any size, coin cells included.

Can I fit a 3V lithium coin cell instead?

No. A CR coded lithium cell runs at 3V, double the voltage here, and it may well be a different thickness too.

How many cells do I actually receive?

Each unit is a sealed card holding two cells, so ordering the minimum of ten units brings you twenty cells in total.

Does the pack print how long the cells last?

No runtime is given for any particular device.
