Description
A pack of two Energizer alkaline coin cells, sized LR43 and also coded 186. The pack states 1.5V, and the chemistry is alkaline rather than lithium or silver oxide. That matters when buying a replacement, because coin cells of the same physical size are made in more than one chemistry and they hold their voltage differently as they drain. The letters at the front of the code tell you which you have: L for alkaline, S for silver oxide. If the cell coming out of your device reads LR43 or 186, this is its direct match.
Cells this small live inside things you open once and would rather not open again: the code is usually printed inside the battery compartment or stamped on the flank of the old cell, so that is the first place to look before ordering. Some devices take a single cell and some take two stacked together, which is where a pack of two earns its keep, since a matched pair fitted at the same time drains at the same rate. Where only one is needed, the second sits in the blister as a spare for the next time.
One unit of this listing is a single blister of two cells. Minimum order is ten units, sold in multiples of ten, so the smallest order brings twenty cells across ten blisters, which suits a service kit or a shop counter better than a single repair. No shelf life figure is stated by the manufacturer. Keep unused cells sealed in their packaging and away from loose keys and coins, and store button cells of any brand out of reach of small children. This listing sits alongside our wider Energizer range, which includes lithium coin cells in CR2032, CR2025 and CR1620, silver oxide SR626, and the AA, AAA, C, D and 9V sizes.

Frequently Asked
What does the 186 in the name mean?
It is an alternative code for the same cell. Manuals and battery compartments print one code or the other, so a device asking for 186 takes an LR43 without any adapting.
How many cells do I actually receive?
Each blister holds two 1.5V cells. The minimum order is ten blisters in multiples of ten, so the smallest quantity we can send is twenty cells.
Can I use this where a silver oxide cell is specified?
This is an alkaline cell, which is why its code begins with L. Where a device asks specifically for a silver oxide cell, coded SR, match what it asks for rather than substituting.
Is it rechargeable?
No. Alkaline coin cells are primary cells, meaning they are designed for a single discharge and should be replaced rather than put on a charger.
Does the manufacturer state a shelf life?
No shelf life figure is given for this cell.
Why buy two when my device only takes one?
Coin cells are easy to lose and awkward to source in a hurry. A sealed spare in the drawer means the next battery change takes minutes rather than a trip out.
