Technical Specifications Of The 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. A more active device such as the new Apple Air Tag which allows constant tracking of objects will only last about a year. 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. As far as service life this will depend greatly on the application. Energizer claims that their lithium coin cell batteries have up to 10 years of shelf life when properly stored. Ideally you would want a battery made of high quality materials, stored in a climate controlled and dry area, with no physical damage. The CR2032 battery is also known as 2032, 5004LC, AWI L14, BR2032, BR2332, CR2032, DL2032, EA2032C, ECR2032, L2032, LF1/2V, LM2032, RFA-35, and Seiko SB-T15.īattery storage life can depend on a variety of factors including material quality, storage conditions, storage time, humidity, physical damage, or temperature. The compact size but relatively high capacity, service life, and consistant discharge make the CR2032 battery an ideal choice for a wide variety of applications. The CR2032 can also be fitted with connection tabs that allow the battery to be fitted in almost any position needed. Commercial uses of the CR2032 battery range from car key fobs and motherboards to security system pannels and weapons sighting systems. The CR2032 is the most common lithium coin cell battery currently used. The CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh, depending on manufacturer specifications. 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.Ĭlick Here To Shop Online For CR2032 BatteriesĬlick Here To Shop Online For CR2025 BatteriesĬlick Here To Shop Online For All Lithium Coin Cell BatteriesĪ CR2032 battery is a non-rechargeable (primary) lithium coin or “button” cell battery that is 20mm diameter x 3.2mm thickness. 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. The first two numbers let you know the diameter of the battery and the last two numbers tell you the height. The R lets you know that the battery is round in shape. The C in CR lets you know the battery uses a lithium chemistry. * MicroBattery Pro-Tip (Understanding Lithium Coin Batteries): Lithium coin cell batteries are usually designated with a CR followed by a set of numbers. After reading this article, we aim to give our customers useful information about the similarities and differences of a CR2025 and a CR2032 battery in order to help them use these oft-confused battery types appropriately. One of the most common questions that we receive from our Microbattery customers is how to determine the correct battery to use for a particular device when presented with battery options that have similar characteristics.
