The black in this is Carbon Black (Acetylene Black). Carbon Black (Acetylene Black) is used in the anode to deliver higher conductivity in the cathode, which in turn yields a number of performance and cost benefits for lithium-ion battery manufacturers. … Continue reading →

DO NOT CONFUSE with the more common and less expensive CR2032. It is well worth checking that you actually want the rare CR3032 (3 cm across) and not the much more common CR2032 (2 cm across). These CR3032 batteries have … Continue reading →

There are two types of 2032 batteries generally available, CR2032 and BR2032 (the capitalization, or lack thereof, for the letters is unimportant, a cr2032 is the same as a CR2032 and a br2032 is the same as a BR2032). Both … Continue reading →

Myth: Button batteries often develop a leak, which leads to tissue injury. Fact: Leaks usually do not occur. Instead an electrical and chemical reaction takes place at the anode surface, which creates tissue erosion. Can lithium button batteries leak? According … Continue reading →
