This is a very important question, and the main difference is their physical size, which makes them completely non-interchangeable.
- CR1220 vs. CR1225: They share the same 12.5mm diameter, but the CR1220 is thinner at 2.0mm compared to the CR1225's 2.5mm. This slight difference in thickness prevents them from being used interchangeably.
- CR1220 vs. CR2032: The CR1220 is much smaller than the CR2032 in both diameter (12.5mm vs. 20mm) and thickness (2.0mm vs. 3.2mm). A CR2032 has a much higher capacity, but it won't fit in a device designed for a CR1220.
Using the wrong size battery will either prevent it from fitting in the compartment or result in a poor electrical connection. Always verify your device's specifications to ensure you purchase the correct battery.
Due to its unique combination of diameter (12.5mm) and thickness (2.0mm), there are no direct drop-in equivalents for the CR1220. While some batteries may have a similar voltage, any difference in size will prevent them from fitting or functioning correctly. For the safety and operation of your device, you should always replace a CR1220 with another CR1220.
No, it is not. The CR1220 is a primary (non-rechargeable) battery and is not built to be charged. Attempting to do so is extremely dangerous and could lead to a serious safety incident, such as the battery leaking, overheating, or even exploding. Once a CR1220 has been depleted, it should be properly disposed of and replaced with a new one.
All coin cell batteries, including the CR1220, demand careful handling. The most critical precaution is to keep them out of reach of children and pets, as they pose a serious ingestion hazard. Additionally:
- Never try to recharge the battery.
- Do not short-circuit the terminals.
- Avoid exposing the battery to fire, extreme heat, or moisture.
- Always dispose of used or damaged batteries responsibly according to your local regulations.
