CR1216 is a button battery, also known as lithium manganese battery.

CR: This is a common code prefix used to indicate that it is a coin cell battery, where the "C" represents the lithium chemistry and the "R" represents the Round shape.
1216: This number indicates the size of the battery. Specifically, it says the battery will be 12mm in diameter and 1.6mm thick.

 

 

Ⅰ.Features of CR1216

Small size: The size of the CR1216 battery is very small, with a diameter of 12 mm and a thickness of only 1.6 mm, which allows the CR1216 battery to be placed in small electronic devices in a very small size without taking up much space.
Stability: CR1216 exhibits stable performance over a wide temperature range and is suitable for equipment under various environmental conditions.
Lithium chemical system: The CR1216 battery uses a LiMn2O4 chemical system, which provides a relatively high energy density, allowing the battery to provide reliable power.
Long life: CR1216 batteries generally last longer than regular lithium-ion batteries because they can continue to provide power for a relatively longer period of time. This is very useful for devices whose batteries are not replaced frequently.
Disposable Batteries: The CR1216 battery is a disposable battery and is not rechargeable. When the battery is depleted, it needs to be replaced with a new one.
Suitable for small devices: often used in small electronic devices, such as watches, calculators, remote controls, LED flashlights, electronic toys, etc.
Low self-discharge rate: It has a low self-discharge rate, which means that even when not used for a long time, the battery will maintain a long storage life and will not lose power easily.
Environmentally Friendly: Because CR1216 batteries use lithium chemistry, they generally have a lower adverse impact on the environment. However, when disposing of waste batteries, proper waste battery disposal methods should be followed to ensure environmental safety.
Light weight, high voltage, high energy density: The battery voltage is 3V, which is almost twice that of ordinary alkaline batteries or manganese batteries. This means the number of batteries required for a device can be halved, maximizing space and weight savings.

Ⅱ.Use of CR1216

LED flash:Some small LED flashes or flashlights use CR1216 batteries. This battery is used for lighting.
Watches:CR1216 batteries are commonly used in various watches and watches to provide power for time display and other functions.
Remote controls:Some small remote controls, such as car remote controls, TV remote controls, and home appliance remote controls, may be powered by CR1216 batteries.
Calculator:Many small calculators use CR1216 batteries to provide power for calculation functions.
Small sensors:Some small sensors and monitoring equipment may be powered by CR1216 batteries, such as temperature sensors, humidity sensors, etc.
Electronic Toys:Small electronic toys, gaming equipment, and children's toys may require CR1216 batteries to operate.
Backlight module:Some small backlight modules, such as watch backlights, small display backlights, etc., may use CR1216 batteries.

IV.Storage method of CR1216

1. Avoid extreme temperatures: CR1216 batteries should be stored in a normal temperature environment and avoid extreme high and low temperatures. Because lithium-ion batteries have higher voltages, extreme temperatures can damage the battery and reduce its performance. The ideal storage temperature range is usually between 0°C and 25°C.
2. Avoid direct sunlight: Batteries should not be exposed to direct sunlight as high temperature and ultraviolet rays may be harmful to the battery.
3. Dry environment: The place where batteries are stored should be in a dry environment. Humid or high humidity conditions may cause the battery to leak.
4. Keep away from fire sources and flammable objects: The battery should be kept away from open flames, heating equipment and flammable objects to prevent fire or damage to the battery.
5. Avoid mixing different types of batteries: Different types and models of batteries have different performance characteristics and should not be mixed and stored in the same place.
6. Avoid physical damage: Batteries should be protected from physical damage during storage, such as being squeezed, bent, or impacted.
7. Check the battery regularly: Even if the battery is not used, the battery should be checked frequently to ensure that there is no leakage, corrosion, or other abnormal phenomena. If there are any abnormalities, they should be dealt with promptly.
