JCB CR2032 Lithium Coin Batteries - 6 Pack

This pack holds six JCB CR2032 lithium coin cells, each rated 3V. The CR2032 code is an international designation rather than a brand or model name, so any device whose manual, old cell or battery hatch is marked CR2032 takes exactly this cell. The CR prefix marks a lithium chemistry, and the four digits give the nominal size of the cell, 20mm across and 3.2mm thick. Each cell is marked CR2032 3V on its positive face, and the pack labels them lithium coin cells.

Coin cells of this size sit in the flat, screw-down or slide-out compartments of small electronics: car key fobs and alarm remotes, kitchen and luggage scales, digital thermometers, bike lights and computer motherboards, where the CR2032 holds the clock and settings while the machine is unplugged. Six in a pack suits a household with several such devices, or a workshop drawer where a flat fob is an inconvenience rather than a planned replacement. The pack carries a keep away from children warning, and coin cells are best stored where small children cannot reach them.

There is nothing to set up: a CR lithium cell is a single use primary cell, so it goes in one way round, marked face towards the plus contact, and it is replaced rather than recharged. The pack does not print a shelf life figure and the manufacturer does not state one. Sold as one pack of six cells, with a minimum order of twelve packs in multiples of twelve, which comes to 72 cells in total. This listing sits alongside our wider range of JCB cells, including single packs of CR2016, CR2025 and CR2032, LR44 coin cells and AA, AAA and 9V sizes.

What does CR2032 mean, and will a different code fit?

CR2032 is an international size and chemistry code rather than a model number, so a device marked CR2032 takes this cell whatever brand came out of it. A cell with different digits is a different size and should not be substituted.

How many cells are in the pack, and how many packs do I have to order?

Each pack holds six 3V CR2032 cells. The minimum order is twelve packs, sold in multiples of twelve, so a first order brings 72 cells in total.

What sort of devices take a CR2032?

Car key fobs, alarm and garage remotes, kitchen and luggage scales, digital thermometers, bike lights and computer motherboards, where the cell keeps the clock and saved settings alive while the machine is off.

Can these be recharged?

No. A CR lithium coin cell is a single use primary cell, so it is fitted once and replaced when flat, and it should never be put on a charger.

Which way round does the cell go in?

The wide face marked CR2032 3V is the positive side, so it faces the plus contact or the sprung lid of the holder, with the rim making the negative connection.
