Here are a few surefire signs that it’s time to get that battery replaced. 1) It will not turn on. 2) Only showing signs of life when connected to a charger. 3) Dying fast even after fully charged. 4) Overheating. … Continue reading →

By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load. Do capacitors decrease current? As the capacitor charges, its … Continue reading →

Depending on the number of cells used, the end of discharge voltage may vary from 1.0–1.1V per cell. It is advisable to use the largest possible number of cells which will satisfy the manufacturer’s charging recommendations, since this will result … Continue reading →

The open circuit voltage goes down and the internal resistance goes up. Note that open circuit voltage is specifically measuring just the voltage the battery puts out with the internal resistance taken out of the equation. That is because there … Continue reading →

“The problem is that, when you exfoliate graphene mechanically through force or by taking a chemical-based approach, you can introduce defects into the structure of the material,” says Koziol. “With the CVD technique, harmful acids might be used to dissolve … Continue reading →

If everything is wired correctly, yes, your car will charge your caravan battery whilst driving. When you start the engine of your car, if the caravan is plugged in, the current of the car (alternator + battery) will recharge your … Continue reading →

Tesla vehicles retain their value well but they are more expensive than other electric vehicles. Teslas don’t always retain value as well as other cars, but they do retain more of that value than other electric cars. Overall, you can … Continue reading →

Yes, a Tesla can be less environmentally friendly than your regular gas car, but it depends on the circumstances. If you own solar panels and use that energy to power your electric vehicle, you are decreasing your carbon footprint despite … Continue reading →

Tesla, being a manufacturer of electric vehicles and a contributor to the green energy ecosystem, earns regulatory carbon credits and sells these to other companies which rely on fossil fuels for their energy needs. For many years, Tesla made good … Continue reading →

“As a charging system, it doesn’t actually work off the alternator. So what it does, it charges as a multi-stage charger; it will charge for a certain percentage and then it will ‘float’ and ‘boost’ when the battery needs the … Continue reading →

Do I need a Sunforce charge controller? No, a solar battery charge controller is only needed for panels of 15W or greater. Will a 1.5 watt solar panel charge a battery? Will a 1.5 watt solar panel charge a car … Continue reading →

Smart alternators are something that’s coming up more and more frequently these days as vehicle manufacturers seek to get their emissions down to meet Euro 5 & 6 regulations. These are commonplace in T6s, Transit customs, Renault Masters and Mercedes … Continue reading →

“A lithium-metal battery is considered the holy grail for battery chemistry because of its high capacity and energy density,” Harvard’s Xin Lee told the Independent. “This proof-of-concept design shows that lithium-metal solid-state batteries could be competitive with commercial lithium-ion batteries.” … Continue reading →

The main difference between a zinc battery and an alkaline battery is the type of electrolyte used in both batteries. Zinc batteries are mostly composed of ammonium chloride while the alkaline batteries use potassium hydroxide. What is a zinc-carbon battery … Continue reading →

Polyurethane upholstery is the most realistic imitation of genuine leather, with respect to hand, surface feel, and overall appearance. When stitched, gathered, or tufted it actually “breaks” or wrinkles like real leather. Is PU or synthetic leather better? But sadly … Continue reading →
