JCB Mixed Lithium Coin Cell Batteries - 6 Pack

This pack holds six JCB lithium coin cells: two CR2016, two CR2025 and two CR2032. All three are 3V cells, which is the standard output of lithium coin chemistry and the reason one cell alone can run a device that would need a stack of alkaline buttons. The three codes share the same 20mm diameter and differ only in how thick they are, the number itself telling you which is which, so a single mixed pack answers the three sizes that come up most often around the home and car.

Coin cells of this kind sit behind car key fobs and alarm remotes, garage door handsets, kitchen scales, calculators, digital thermometers, bike lights, fitness bands, small torches and the memory cell on a computer motherboard. The CR2032 is the one most often called for, which is why keys and remotes tend to go flat at the least helpful moment; having a spare of each thickness in a kitchen drawer turns a trip to the shop into a two minute job. Because the cells are separated on the card, you can lift out one at a time and leave the rest sealed until they are needed.

To be sure of the right cell, read the code printed on the face of the one you are taking out, or check the inside of the battery door; the device will name a CR number rather than a size in millimetres. A CR2032 will not drop into a holder built for a CR2016, so match the code rather than the diameter. The pack carries a warning to keep batteries away from children, and coin cells are worth storing well out of reach. One unit is a card of six cells, and the minimum order is 12 units, sold in multiples of 12. We also stock the CR2016, CR2025 and CR2032 on their own, and JCB LR44 coin cells.

Which of the three cells does my car key fob take?

Read the code stamped on the face of the cell you are removing, or check inside the fob casing. Many fobs call for a CR2032, but CR2025 and CR2016 both turn up.

What is the difference between CR2016, CR2025 and CR2032?

All three are 20mm across and give 3V. The last two digits give the thickness in tenths of a millimetre, so they run 1.6mm, 2.5mm and 3.2mm, the CR2032 being the thickest.

How many of each size do I get?

Two of each: two CR2016, two CR2025 and two CR2032, six cells in total on a single card with the code printed beside each cell.

Can I fit a CR2032 where a CR2025 is called for?

They share a diameter and a 3V output, but the CR2032 is thicker and will not always seat in a holder built for the thinner cell. Fit the code the device names.

Why is the minimum order 12?

This line is sold in trade quantities, so orders go in multiples of 12 cards. That works out at 72 cells, which suits a workshop, an office or anyone keeping spares in stock.
