A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed battery or maintenance free battery, is a type of lead-acid rechargeable battery. Gel Cell, Absorbed Glass Mat (AGM), and Wet Cell are various versions of lead acid batteries. The Wet comes in two styles: serviceable, and maintenance free. Gel Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium Wet Cell battery.

Yes, there are several step-by-step guides available for constructing a microbial fuel cell (MFC). These guides typically outline the necessary materials, such as electrodes, a container, and a microbial culture, as well as detailed instructions on assembling the components, preparing the culture, and optimizing the conditions for electricity generation. Many resources, including academic papers, DIY science websites, and educational videos, provide comprehensive instructions for building an MFC at home or in a laboratory setting.
Electrochemistry consists of a variety of diverse and significant applications to modern industrial and commercial processes in the 21st Century. These applications most commonly include the purification of metal and the ability to convert the chemical energy of a simple voltaic cell reaction into electrical energy.

A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.
