| The choice between lithium and Silver Oxide batteries is a matter of voltage. Lithium batteries have a nominal 3 volt output, and silver oxide batteries operate at 1.5 volts. So, youll want to find out what type of voltage is required for the device youre using. The easiest way to do so is by looking at the battery being replaced, which should have all the info you need. Battery requirements can also be found in product manuals, and often on the product itself. |
All coin cell lithium batteries consist of lithium manganese dioxide chemistries (Li-MnO2), which account for 80% of the lithium battery market. Li-MnO2 chemistry is denoted by the IEC prefix “CR”, which well discuss more below. Because it operates at 3 volts, one Li-MnO2 can replace two alkaline or silver-oxide cells, which function at 1.5 volts. Its worth noting that voltage can be subject to fluctuate slightly depending on the quality of the battery maker. So, the more reputable the company, the more likely the battery will be of maximal quality.
