A single car has about 30,000 parts, counting every part down to the smallest screws, nuts and bolts. Some of these parts are made by the manufacturer, but there are lots of suppliers that make many of these parts. The … Continue reading →

Not all lead acid batteries are nominally the 12V variety. Common battery voltages available are 6, 12, 18, 24 Volts et al. A fully charged cell is 2.14 Volts. At what voltage is a 12V lead acid battery fully charged? … Continue reading →

When a battery is expired, it means that the battery’s manufacturer can no longer guarantee that the battery has a full life or charge. More specifically battery expiration dates are based upon when the battery’s total self-discharge will exceed 20%. … Continue reading →

60% of the battery is made up of a combination of materials like zinc (anode), manganese (cathode) and potassium. These materials are all earth elements. This combination of material is 100% recovered and reused as a micro-nutrient in the production … Continue reading →

About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. Is car battery lead pure? Battery Glossary – Pure Lead … Continue reading →

Pros and Cons of Solar Energy Advantages of Solar Energy Disadvantages of Solar Energy Renewable Energy Source Cost Reduces Electricity Bills Weather Dependent Diverse Applications Solar Energy Storage is Expensive Low Maintenance Costs Uses a Lot of Space What is … Continue reading →

The most recent research indicates that lead can damage the infant brain even at blood levels as low as 5 μ/dl (5). These findings, together with data showing that lead can damage the catalytic converters of cars, have triggered strong … Continue reading →

Pencil lead is not lead at all; it’s a combination of finely ground graphite and clay, mixed with water and pressed together at high temperatures into thin rods. We call it lead is because the Englishmen who first discovered graphite … Continue reading →

Materials conduct electricity if one of two things happens: If electrons can move around freely (as in the delocalized bonds of metals), then electricity can be conducted. If ions can move around freely, electricity can be conducted. Why do some … Continue reading →

Covalent molecular substances which are acidic or basic react with water producing free mobile atoms. The resulting ions are able to move freely throughout the solution carrying charge and hence conducting an electric current. Why do some molecular compounds conduct … Continue reading →

The definition of an ionic compound, is a chemical compound composed of ions held together by electrostatic forces – basically held together by ionic bonds. They are formed by neatly packed ions of opposite charge. The compound is neutral, but … Continue reading →

Are there no 12V batteries in hybrid cars? A. No. A hybrid vehicle consists of a high-voltage battery that runs the electric motor and a 12V low-voltage battery that powers the automotive electronic system. Why do hybrids have 12 volt … Continue reading →

Therefore, alkaline batteries should be separated from the rechargeable batteries and disposed of as normal trash. Lead acid batteries are found in Uninterruptible Power Supply (UPS) units and vehicles. These batteries have a lead anode, a lead dioxide cathode and … Continue reading →

Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. What are the disadvantages of lead acid batteries? Drawbacks or … Continue reading →

A secondary cell, commonly referred to as a rechargeable battery, is an electrochemical cell that can be run as both a galvanic cell and an electrolytic cell. Are secondary cells galvanic or electrolytic? A secondary galvanic cell is a type … Continue reading →
