CR2 Single Use Batteries
CR2 batteries are a type of 3-volt lithium battery. They are generally used to power many cameras and recording devices. Here are some common features for this type of single use battery.What type of battery is a CR2?
- Lithium: A lithium battery features a lithium anode. These batteries can be either disposable or rechargeable.
- 3-volt: All CR2s are 3-volt, which is simply the amount of charge they hold. This is a common voltage.
- Disposable: Most CR2 batteries are disposable as well. They also often come in double packs.
Commonly used to power cameras as well as other photographic equipment, CR2s resemble a C battery. While most often used for photography, they can also be found in several other types of equipment:
- Stun pens: Similiar to a stun gun, a stun pen is used to stun an attacker. These pens look similar to highlighters.
- Laser pointers: While most laser pointers do not use CR2 batteries, there are a few models that do.
- Flashlights: There are also many flashlights that use these batteries. Most of them can be found in medical settings.
- Palm pilots: There are some palm pilots that also use CR2s. They are most often found in hospitals and schools.
- Medical instruments: Another common usage for CR2s are in some medical instruments. These can include recording devices and tools used for surgery.
CR2s were commonly used in cameras during the late 1990s and 2000s. Here is a list of some types of cameras that use CR2 batteries:
- 35 mm film cameras: 35 mm film is a type of recording device used to take still photography. Many of them are made by Kodak, Nikon, Olympus, and Canon.
- Advanced Photo System (APS) cameras: APS was a type of film used in many still camera models. They were often made by Kodak and Fujifilm.
- Digital cameras: Many digital models in the late 1990s and 2000s used these batteries as well.
While the 2 lithium batteries appear the same, CR2s are actually smaller than their CR123 counterparts. They often are confused with one another, so be careful to look for the right type when getting ready to take photos. They should have a label on the side of the battery as well as on the outer packaging.
