How do you do a bump start? Bump starting is using the momentum of the vehicle to spin the engine by moving the vehicle while the clutch is depressed and then letting off the clutch instantly transferring most of the … Continue reading →

A flooded battery with lead-acid chemistry is the most common in the industry compared to a sealed lead-acid battery, which are sometimes referred to as a valve regulated battery, an AGM battery (Absorbed Glass Mat) or a gel battery. Are … Continue reading →

Yes, you can paint over lead paint and it’s safe. It forms a barrier against the toxins in the lead paint. However, it’s only safe and effective if the lead paint’s old finish is in good condition. Also, you can’t … Continue reading →

In a lead-acid battery, the cathode is made of lead-dioxide, and the anode is made of metallic lead. The two electrodes are separated by an electrolyte of sulfuric acid. Why is anode negative in lead acid battery? Anode and Cathode … Continue reading →

Ionic solids are very hard and brittle. Hard due to the strong bonds. Brittle since when distorted like charged ions move closer to each other and the strong electrostatic repulsions shatter the crystal. Ionic solids cannot conduct electricity. Why ionic … Continue reading →

12.6 volts. The standard automotive battery in today’s vehicles is a 12-volt battery. Each battery has six cells, each with 2.1 volts at full charge. A car battery is considered fully charged at 12.6 volts or higher. When the battery’s … Continue reading →

There are different types of contacts in a contactor, and they are; auxiliary contact, power contact, and contact spring. The power contact has two types that are; stationary and movable contact. Material for making contacts must have a high welding … Continue reading →

Ionic liquids are often addressed as “Green Solvents” or are connected with “Green Chemistry”. These claims have been made because many ionic liquids have a negligible vapor pressure. Why ionic liquid is a green solvent? Ionic liquids hold potential as … Continue reading →

Simple answer – No. Different types of battery have different maximum currents they can supply. This is limited by their ‘internal resistance. Are all 12V batteries interchangeable? No. Car batteries differ in multiple ways to work with different vehicle’s specifications, … Continue reading →

A Tesla is the one car you own and use to get to work. You need to install an Ignition Interlock, but you’re told by a provider that they can’t install their device into your Tesla. Do interlocks mess up … Continue reading →

The high voltage battery is charged using a charging cable. The battery can also be charged via charging stations with an integrated control unit. What is the best way to charge the HV battery? Use a regular household plug to … Continue reading →

one hour. The amp-hour rating tells you how long the battery will last before it goes flat. For example, a 7.2Ah battery will give 7.2 amps for one hour or 3.6 amps for 2 hours or 1.8 amps for 4 … Continue reading →

Over the life of a battery, discharge-recharge reactions happen thousands of times. Each cycle wears out the plates a bit, and over time the lead deteriorates. As your car battery loses capacity, cold cranking amps decrease. What causes a battery … Continue reading →

Impure metals for the anode or cathode can cause a voltage change. Surface coating can cause a voltage drop. The acid or base concentration can cause a voltage change. The ionic strength of the solution can change the voltage. What … Continue reading →

The calculation is based on the following: The average “membrane potential” for a cell is 70 millivolts OR . 07 volts (this the electrical charge difference between the inside of the cell, separated by the cell membrane, from the charge … Continue reading →
