Batteries

A maintenance routine is recommended in order to achieve maximum service life from batteries. Checklist to observe is as follows: 1. Ensure that all terminal lugs are clean and tight, to give good electrical contact. 2. Ensure that connecting straps and cables are of a suitable material and in good …

In order to compare batteries, an electrician must first know what parameters (specifications) to consider. Terminal Voltage The most identifiable measure of a cell is the ‘terminal voltage’, which at first may seem too obvious to be so simple. In fact, the terminal voltage can change dramatically as a cell …

Electrolytic corrosion is created by contact between two different metals in a damp atmosphere with dust or pollution of a type that will dissolve in water. Precautions may have to be taken to ensure that the join between two different metals is kept dry. Dissimilar Metals The best-known effect of …

Electrochemical reaction, any process either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances—one a solid and the other a liquid. Electrolysis Pure water is a very poor conductor of electricity, but if a small amount of an acid, alkali …

Lithium Ion batteries are one of the most durable and reliable energy sources on the market and a drastic improvement over lead-acid in weight, capacity, and shelf life. Lithium Ion Batteries are the safest lithium chemistry with the highest cycle life and are compatible with most standard chargers. Lead acid …

Definition: A secondary cell can be recharged or restored. The chemical reaction that occurs on discharge may be reversed by forcing a current through the battery in the opposite direction. This charging current must be supplied from another source, which can be a generator or a power supply.  Figure 1 …

The purpose of a battery charger is to charge a battery without overcharging it. The simplest type of charge controller for renewable energy systems monitors the battery voltage and turns the charging current off or reduces it when the battery voltage exceeds a specified level. It turns the charging current …

This particular article talks about the battery sizing for certain applications such as Uninterrupted Power Supply (UPS), solar PV system, telecommunications, and other auxiliary services in power system. Whatsoever the practical application, batteries are proven technology to store an electrical energy. Other than storage purposes, batteries are extensively utilized in …

Lead-Acid Battery Construction The lead-acid battery is the most commonly used type of storage battery and is well-known for its application in automobiles. The battery is made up of several cells, each of which consists of lead plates immersed in an electrolyte of dilute sulfuric acid. The voltage per cell …

Primary and Secondary Cells The simple voltaic cell is classified as a primary cell. Primary cells can supply current until the negative electrode is completely dissolved, the electrolyte is exhausted, or perhaps until polarization renders the cell useless. A secondary cell, on the other hand, can be recharged. That is, …

Voltaic Cell Definition A voltaic cell consists basically of two different metal plates immersed in an acid solution. The action of the acid removes electrons from one plate and accumulates them on the other plate. In this way, a potential difference is produced between the two plates, and a current …
