Because of their attributes, lithium ion batteries and cells are more suitable for some applications than others. They provide high levels of charge than other battery technologies, and they have a higher voltage, and can often cost more than some … Continue reading →

According to a new investigation performed by Amnesty International, Apple is one of several technology companies using cobalt mined by child labor in their lithium-ion batteries. Who is Apple’s lithium supplier? The report says that Foxconn, one of Apple’s largest … Continue reading →

If the battery is only mildly discharged, the current consumed by the battery during recharge is determined by the battery itself. The larger battery has more capacity in the first place, so its voltage will drop less than a smaller … Continue reading →

18650 are housed inside of a steel case, some 18650 poor quality ones lack protection. The lack of protection in 18650 batteries causes the internal pressure inside of the battery to increase abruptly when the battery overcharge. When that happens … Continue reading →

You’ll discover that dry foods, like crackers, have high energy density (calories more than twice the grams). Surprisingly, fat-free pretzels have the same energy density as cheese. Munching on these without controlling your portions can quickly add weight. What food … Continue reading →

Low energy density means there are few calories in a lot of food. When you’re striving for weight loss, the goal is to eat low-energy-dense foods. That is, you want to eat a greater volume of food that’s lower in … Continue reading →

Most people think that tyres wear much quicker on electric vehicles than they do on conventional cars. In truth , it depends. Tests have shown that for a like-for-like comparison EVs with 2 wheel drive systems can reduce tyre mileage … Continue reading →
