Environmental impact While safe for the landfills, the physical mining of lithium and the production of lithium-ion are both incredibly labor intensive with a majority of it not being recycled, causing the impacts on the environment to be costly. Why … Continue reading →

No. You cannot use just any charger to charge any rechargeable battery. First off, battery chargers use charging protocols to charge specific battery chemistries. Some chargers can charge multiple chemistries by detecting the battery type and apply the proper charging … Continue reading →

about 0.02 ohms. The internal resistance of a 12-volts car battery is about 0.02 ohms. How much resistance should a 12V battery have? The resistance “seen” by the 12-Volt battery is 500 ohms . What is the internal resistance of … Continue reading →

The magnitude of emf is equal to V (potential difference) across the cell terminals when there is no current flowing through the circuit. Source: en.wikipedia.org. varepsilon = frac {E}{Q} varepsilon = I (R+r) varepsilon = IR + Ir. varepsilon = … Continue reading →

When a Dead Battery Is Really Dead It may no longer be possible to fully charge it, and a full charge may not last as long. Leaving a battery dead can also cause serious problems, as the lead sulfate can … Continue reading →

The lead acid batteries in cars are designed to provide the huge current needed to start the vehicle. They do that well, they don’t do very much else well. These batteries become damaged if they are drained to less than … Continue reading →

Batteries basically work where the chemistry has an electrical charge; chemical reaction results in electrical discharge, which is used to power stuff like your TV remote or Gameboy. The process for alklaine (non-rechargeable) batteries is not reversible, which is why … Continue reading →

Robert Victor Neher. Robert Victor Neher took out a patent for the continuous rolling process and opened the first aluminium rolling plant in Kreuzlingen, Switzerland. Bern-based Tobler began wrapping its chocolate bars in alufoil including the unique triangular chocolate bar, … Continue reading →

Alkaline AA cells have a weight of roughly 23 g (0.81 oz), lithium AA cells around 15 g (0.53 oz), and rechargeable Ni-MH cells around 31 g (1.1 oz). Is a AA battery a lithium battery? Consumer-sized lithium ion batteries … Continue reading →

Basically, all the electrochemical cells and batteries are classified into two types: Primary (non-rechargeable) Secondary (rechargeable) What are the 2 types of battery? There are two basic types of batteries: primary and secondary. Primary batteries are “single use” and cannot … Continue reading →

Gabapentin is an anticonvulsive medication that originally saw use as a muscle relaxer and anti-spasmodic medication, but later it was discovered it had the potential of the medication as anticonvulsive medication and as an adjunct to more potent anticonvulsants. Is … Continue reading →

At concentrations higher than 10(-4) g/ml, sodium valproate hyperpolarizes the smooth muscle tissues, reduces the frequency and amplitude of the spontaneously generated spike potentials and relaxes the preparations. These effects are blocked by picrotoxin. What is sodium valproate used for? … Continue reading →

Tesla increased the top speed of the Model 3 Performance from 155 mph (250 km/h) to 162 mph (261 km/h). Interestingly, in their video, the 2021 Model 3 Performance reached the top speed of 262 km/h — 1 km/h above … Continue reading →
