Sila. Sila Nanotechnology, a Silicon Valley-based battery materials company backed by Daimler, said the first commercial application of its silicon-based anodes is for a new fitness tracker and that its longer-term goal is to help get lower-cost, longer-range electric cars … Continue reading →

There was also a “No. 6″ battery that was larger than the others and pretty commonly used, so it was grandfathered in without a name change. While you typically won’t see either A or B batteries on American store shelves, … Continue reading →

A cell refers to a single anode and cathode separated by electrolyte used to produce a voltage and current. A battery can be made up of one or more cells. A single AA battery, for example, is one cell. Car … Continue reading →

They contain a lead dioxide or lead sulfate cathode, a lead anode and a sulfuric acid electrolyte. What should I do with my used batteries? Alkaline and Carbon zinc batteries can be discarded with regular household trash if dated after … Continue reading →

A torch bulb is made up of spherical glass which is attached to a metallic base. There is a filament inside the bulb. The filament is attached to two wires. One of the wires is attached to the metallic base … Continue reading →

Larger button batteries will overload smaller ones and cause them to bulge and burst. Anytime a lithium battery does this, it not only creates a situation you need to carefully clean up, but it releases some heat, and the more … Continue reading →

Permanent battery sulfation can cause a variety of issues including: Loss of starting/cranking power. Substantially longer charging times. Increased heat build-up. Shorter running times between charges. dramatically shorter battery life. complete battery failure. What happens when a battery is sulfated? … Continue reading →

Distilled water is water that was boiled to steam and recondensed to water. So distilled water is relatively pure H2O. Water can ionize to H+ and OH- like salt does, but it ionizes to a far lesser degree and is … Continue reading →

The lead accumulator refers to a secondary cell as the electrical energy doesn’t generate itself inside the cell, but it is stored prior to an external source. It’s a reversible cell as the cell reactions are in the reversed state … Continue reading →

Lithium batteries typically have a shelf life of 10–12 years, although some manufacturers claim that certain models will last up to 20 years. Alkaline batteries usually have a shelf life of 5–10 years. Carbon zinc batteries have a shorter shelf … Continue reading →

The RPG-7 is the default rocket launcher for the Russians. The angle you hit the target with the RPG affects damage output. Since the rockets are high velocity, they are generally easy to use. The Javelin and the SRAW are … Continue reading →

Three 1.5 V battery cells in series are like three houses stacked on top of each other. Their heights add together, so their total voltage is 4.5 V. Yes, the final voltage when the three 1.5 batteries are connected in … Continue reading →

Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move. Ionic compounds are conductors of electricity when molten or in solution, and insulators when solid. Are metals better conductors than ionic compounds? … Continue reading →

By the Industrial Revolution, lead was a well-known killer. But it was just so handy. The lead industry liked to call lead “the useful metal.” It was adaptable to just about any commercial purpose, including mass-produced lead plumbing, lead alloys … Continue reading →

Prevent Rusting Along with corrosion, petroleum jelly is also good at keeping rust off your tools and other metal goods. Lightly coat your tools after you clean them with a bit of Vaseline and you’ll be set to go. What … Continue reading →
