CR2330 Battery Equivalent
When it comes to finding an equivalent to the CR2330 battery, the primary concern should be finding a battery of the same size and voltage. The CR2330 refers to a lithium button/coin battery with a diameter of 23mm and a thickness of 3mm, and a nominal voltage of 3V. The "CR" in CR2330 stands for the Manganese-Dioxide Lithium chemistry used, which gives this battery a relatively high capacity and discharge current compared to other chemistries.
Broadly speaking, the following battery types can be considered as equivalent to CR2330, since they share the same physical dimensions and voltage:
BR2330: This battery has similar physical dimensions and voltage to the CR2330, but the primary difference lies in the battery chemistry. A BR2330 battery employs Carbon-Monofluoride Lithium chemistry, which offers a lower discharge current but presents a longer shelf life.
DL2330: This is Duracell’s designation for the same type of battery as the CR2330. The DL simply stands for "Duracell Lithium".
E-CR2330: This is Energizer's number for the CR2330, with the E standing for "Energizer".
KCR2330, LM2330, and KECR2330: These are also equivalent batteries produced by different manufacturers.
CR2330 vs BR2330 Battery
CR2330 and BR2330 batteries share the same physical dimensions - a diameter of 23mm and a thickness of 3.0mm. However, the major difference between them lies in their chemical composition, which impacts their operation under different conditions and their overall lifespan.
| Properties | CR2330 Battery | BR2330 Battery |
|---|
| Chemistry | Manganese-Dioxide Lithium (Li-MnO2) | Carbon Monofluoride Lithium (Li-(CF)n) |
| Voltage | 3.0V | 3.0V |
| Capacity | Approximately 265mAh | Slightly less than CR batteries but still in a similar range. |
| Operating Temperature | These batteries generally operate between -20°C to +60°C (may vary slightly based on the manufacturer's specifications) | These batteries can operate over a wider temperature range, typically -30°C to +85°C, again, based on manufacturer's specifications. |
| Discharge Characteristics | They can deliver a relatively high pulse load, making them suitable for devices with occasional high power consumption. | BR batteries have lower self-discharge rates, resulting in a longer shelf-life and operational lifespan, especially in low drain devices. |
In summary, if your device requires a high pulse current, the CR2330 would be more suited to your needs. However, if your device operates in extreme temperatures or needs to last for a long time without replacing the battery, a BR2330 could be a better choice.
Is LiR2330 the equivalent battery of CR2330?
While the LiR2330 and CR2330 batteries share the same physical dimensions (23mm diameter and 3.0mm height), they are not strictly equivalent due to differences in their voltage and rechargeability.
Voltage difference: A standard CR2330 battery has a nominal voltage of 3.0V. On the other hand, a LiR2330 is a rechargeable lithium-ion battery with a voltage that typically starts around 3.6V when fully charged and decreases as the battery discharges but generally stays above 3.0V for most of its capacity.
Rechargeability: CR2330 is a disposable battery designed for a single use, while LiR2330 is designed to be recharged and used multiple times.
These differences mean that although the LiR2330 might fit into a device that needs a CR2330 battery, it may not function correctly or safely. For instance, the higher beginning voltage of a LiR2330 might potentially damage a device designed to run at the lower voltage provided by a CR2330 battery.
Therefore, while theoretically possible, it's not recommended to replace a CR2330 with a LiR2330 without confirmation from the device's manufacturer or a professional. Always check the device manual or consult with the device’s manufacturer regarding battery replacements to ensure you use a compatible and safe alternative.
Application
The application scenarios of CR2330 are similar to other button batteries. The following are common applications of CR2330 batteries:
Watches and clocks

Toys and games
LED lights
Small electronic devices, such as laser pointers and digital thermometers
