CR2012 coin cells have been popular among major timepiece manufacturers such as Bulova, Timex, Seiko and Citizen, making this tiny battery one of the most common replacement batteries for name-brand wristwatches. This flat circular lithium battery also powers the backup memory on many electronics like digital cameras and e-readers, protecting against critical data loss when the main battery is removed.
The CR2012 coin cell battery features an exceptionally long shelf life (between 5 and 10 years) along with a low-drain rate, often providing many years of service before requiring replacement. Weighing in at a mere 1.4g and measuring about 1.23mm high with a 20mm diameter, this battery is highly resistant to leakages, making it safe and comfortable for use in wearable devices such as wristwatches and medical monitoring equipment like heart rate monitors.
