Understanding the CR1220 Battery: Features, Applications, and Replacements
In our modern, technologically-driven society smaller power sources such as battery cells for coin-cells are vital. In this regard they are they include the C1220 button cell is a popular button cell made of lithium which powers a range of electronic gadgets that are small in size. Car key fobs to fitness trackers to Digital thermometers. This little battery plays a significant part in our everyday technology usage.
If you’re seeking details about the CR1220whether to replace, compatible or understanding how it functions this guide will provide the most important aspects.
What Is a CR1220 Battery?
The CR1220 is an 3V coin cell made of lithium which belongs to the CR-series batteries. The label of the CR1220 informs us:
- “C”: Chemistry of lithium
- “R”: Round shape
- “12”: 12 mm in diameter
- “20”: 2.0 millimeter thickness
This is 12mm x 2.0mm coin battery made of lithium. It produces 3 voltages and provides an extended shelf life and stable performance in comparison to alkaline batteries.
Key Features of CR1220 Batteries
- Nominal Voltage: 3.0V
- Capacity: Approximately 35-40 mAh
- Shelf Life 5-10 years
- Operating Temperature: -20degC to +60degC
- Chemistry: Lithium Manganese Dioxide (Li-MnO2)
Thanks to their lithium chemistry, CR1220 batteries offer low self-discharge and reliable power delivery over a long time — even in temperature-sensitive applications.
Common Applications
The CR1220 batteries are typically found in:
- Car key remotes
- Wristwatches
- Fit trackers
- Digital thermometers
- Motherboards (for memory backup)
- Miniature toys and devices
Their slim design allows them to be used in appliances where room is at a top priority, but power that lasts for a long time is essential.
CR1220 Vs. Others Coin Cells
Many people mistake the CR1220 coin cell with other similar ones such as the CR1216, CR1225 as well as the CR2032. This is how CR1220 differs from:
| Battery | Size (mm) | Voltage | Capacity | Interchangeable? |
| CR1216 | 12 x 1.6 | 3V | ~25 mAh | Only if the thickness is sufficient. |
| CR1225 | 12 x 2.5 | 3V | ~50 mAh | Not recommended due to the thickness |
| CR2032 | 20 x 3.2 | 3V | ~220 mAh | Too large in size |
| CR1220 | 12 x 2.0 | 3V | ~35 mAh | — |
It is essential to select the correct battery that has both physical and voltage for a perfect functionality and fit.
CR1220 Battery Equivalents
If you’re in the market for a new battery, here are some typical battery alternatives for CR1220 and alternate names for different brands:
- DL1220 – Duracell
- ECR1220 – Energizer
- KCR1220 – Kodak
- RSS0_BR1220 (also known as Panasonic (uses a slightly distinct chemistry but is compatible in various devices)
- LM1220 – Maxell
Although there are slight differences in the names the batteries are usually interchangeable if the voltage and dimensions match. However, for electronics that are sensitive it is recommended to verify the compatibility of your device’s in the manual.
