CR2016 vs CR2032
The CR2016 is far thinner (1.6mm) than the CR2032 (3.2mm). Both are 20mm 3V cells, but a thin 1.6mm holder cannot take a 3.2mm CR2032. Match the height printed on the old cell.
| CR2016 | CR2032 | |
|---|---|---|
| Diameter | 20mm | 20mm |
| Thickness | 1.6mm | 3.2mm |
| Voltage | 3V | 3V |
| Capacity | ~90mAh | ~220mAh |
What are the CR2016 battery characteristics?
These are the CR2016 performance figures we declare under EU Regulation 2023/1542: rated capacity and the maximum available duration under a standard continuous load. Real discharge performance depends on load, temperature and cut-off voltage, so the exact test conditions are stated underneath the table.
| Capacity | MAD |
|---|---|
| 75mAh / 0.225Wh | 700hours |
| 80mAh / 0.24Wh | 800hours |
| 90mAh / 0.27Wh | 900hours |
| 100mAh / 0.30Wh | 1000hours |
Capacity & MAD test condition: 30kΩ continuously to 2.0V @ 20±2℃
Shelf life: One year after delivery under normal storage, 98% of initial capacity maintained
EU Declaration No. TQ-EUDOC-CR2016-20260622 · Compliant with Regulation (EU) 2023/1542
What batteries are equivalent to the CR2016?
The CR2016 is interchangeable with any cell of the same diameter, thickness and voltage, so an equivalent can be substituted without changing the device. Buyers look these cells up under three numbering systems at once — IEC, ANSI and manufacturer codes — and the list below covers the names the CR2016 is sold under.
Look any number up in the cross-reference tool → — type the marking on your cell and see where it lands, or pick your device and see the cells we supply for it.
Same cell, other designation or brand code — direct replacement
| Number on the cell | Published by |
|---|---|
| 5000LC | ANSI / NEDA designation for this size — Energizer CR2016 product datasheet, printed as “Designation: ANSI / NEDA-5000LC, IEC-CR2016” (data.energizer.com) |
| ECR2016 | Energizer (own model) · Maxell cross-reference chart, Energizer Eveready column |
| DL2016 | Duracell (own code) · Maxell cross-reference chart, Duracell column |
| KECR2016 | Rayovac (own code) · Maxell cross-reference chart, Rayovac column — single source, treat as unconfirmed |

| CR2016 — the same code is printed by Maxell, Panasonic, Varta, Renata, Rayovac and Toshiba | Maxell cross-reference chart, which carries a column for each of those makers at this size |
Same diameter, thicker cell — check the holder before substituting
| Number on the cell | Published by |
|---|---|
| CR2025 | IEC 60086 size designation, 20.0 × 2.5 mm — 0.9 mm thicker than CR2016 |
| CR2032 | IEC 60086 size designation, 20.0 × 3.2 mm — 1.6 mm thicker, so it will not fit a compartment cut for CR2016 |
Where is the CR2016 battery used?
The CR2016 is used in car key fobs, motherboards and other compact devices that draw small currents over long periods. Its 3.0V output and 75mAh ~ 100mAh capacity suit equipment that has to run for months without a battery change. The blocks below set out what to check for each device type.
CR2016 in Car Key Fobs
Most modern car key fobs and remote controls run on a CR2016 coin cell. Nissan, Honda and Toyota remotes commonly use the CR2016 (check the exact cell printed inside before ordering). When the range drops, the fob battery is usually the first thing to change.
CR2016 for Motherboard CMOS
The motherboard CMOS battery keeps your BIOS settings and system clock powered when the PC is off. Many desktop boards and laptops use a CR2016 — a dead cell is the usual cause of a "wrong system time" or lost BIOS settings on boot.
CR2016 for Apple AirTag
The Apple AirTag runs on a removable CR2016 coin cell. To replace it: press and twist the back cover open, swap the old cell for a fresh CR2016, then re-seat the cover. A new CR2016 keeps your AirTag powered and alerts you when it gets low.
What do buyers ask about the CR2016 battery?
Need the CR2016 priced, or the same cell printed and packed under your own brand? Send the quantity, the target market and the packaging format, and we return price, MOQ band and the CR2016 data sheet.
Printed, blister-carded and boxed in our own plant, from 50 cartons per product line. Samples are available before a production run — tell us the device the cell goes into.
