Lithium Coin

*MicroBattery Pro-Tip (Understanding Lithium Coin Batteries): Lithium coin cell batteries are usually designated with a CR followed by a set of numbers. The C in CR lets you know the battery uses a lithium chemistry. The R lets you know that the battery is round in shape. The first two numbers let you know the diameter of the battery and the last two numbers tell you the height. So by following this, you can easily see that a CR2032 battery is a (C) lithium chemistry battery with a (R) round shape that has a diameter of (20) 20 millimeters and a height of (32) 3.2 millimeters. This applies to the majority of coin and button cell batteries but note there are some exceptions, like the CR2 or CR123A batteries which are considered lithium cylindrical batteries.

What Battery Is Equivalent To The CR2032 Battery?

The CR2032 battery is also known as the 5004LC, BR2032, CR2032, DL2032, ECR2032, KCR2032, and KECR2032 depending on the manufacturer. Other lithium coin cell batteries may have a similar voltage, diameter, or height as the CR2032 battery, but may not work in devices that require a CR2032. For example, a CR2016 has the same diameter and voltage as the CR2032, but has half the height and may not fit securely into the device you are trying to power. A CR1632 battery would have the same height and voltage of the CR2032 but would have a diameter that is 4mm too short to securely fit in the same device. It is important to understand the specifications of your device’s battery in order to get the best use out of the battery.

How Long Do a CR2032 Batteries Last?

Battery storage life can depend on a variety of factors including material quality, storage conditions, storage time, humidity, physical damage, or temperature. Ideally you would want a battery made of high quality materials, stored in a climate controlled and dry area, with no physical damage. Energizer claims that their lithium coin cell batteries have up to 10 years of shelf life when properly stored. As far as service life this will depend greatly on the application. A CR2032 battery in a car key fob may last up to 4-5 years before needing replacement as the use of the battery is very intermittent. A more active device such as the new Apple Air Tag which allows constant tracking of objects will only last about a year.

What Uses a CR2032 Battery?

The CR2032 battery is used in a wide variety of devices and applications including computer motherboards, car key fobs, watches, calculators, PDAs, electronic organizers, garage door openers, toys, games, door chimes, pet collars, LED lights, sporting goods, pedometers, calorie counters, stopwatches and medical devices.
