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 →

The gold nanowires are strengthened by a manganese dioxide shell encased in an Plexiglas-like gel electrolyte. The combination is reliable and resistant to failure. After cycling a test electrode about 200,000 times, no loss of capacity or power, nor fracturing … Continue reading →

Due to the large size of wet cells, they can be only used in larger equipment, e.g. car batteries, and cannot be used in small devices, like mobile phones. Dry cells have a higher energy density compared to wet cells. … Continue reading →

Properly maintained deep-cycle batteries should last for 6 or more years. Unfortunately some RV owners replace RV batteries every year or two. Extending battery life is not difficult; it just requires some basic care & maintenance. When should I replace … Continue reading →

An electrolytic cell is an electrochemical cell in which the energy from an external power source is used to drive a normally non-spontaneous reaction, i.e. apply a reverse voltage to a voltaic cell. What is the difference electrochemical cell and … Continue reading →

The lead–acid battery consists of two electrodes submerged in an electrolyte of sulfuric acid. The positive electrode is made of grains of metallic lead oxide, while the negative electrode is attached to a grid of metallic lead. Lead–acid batteries are … Continue reading →

Sometimes known as a voltaic cell or Daniell cell is a galvanic cell. One example of a galvanic cell is the common household battery. The electrons flow from one chemical reaction to another occurs through an external circuit that results … Continue reading →
