Samsung Showcases Quick-Charging EV Batteries

  Samsung Showcases Quick-Charging EV Batteries Samsung Electronics joined this year’s NAIAS 2018 to showcase its new EV batteries.Korea Herald learned Monday that Samsung SDI is presenting its newest inventions for the battery and renewable energy market. The South Korean tech giant’s lineup comprises rapid-charging batteries, multifunctional module packs and low height battery cells. Samsung said its new batteries are capable of increasing electric car range and charging capacity.

Ali vs Frazier. Harding vs Kerrigan. Vader vs Kenobi. The NBN vs the entire country of Australia. These are the great rivalries of our histories. In the world of cricket, there’s no greater rivalry than that of England vs Australia in the five match Test extravaganza known as ‘The Ashes’.

Clearly, these cheaper batteries are not nearly as good as the more expensive ones. Ok, but what about the total energy? How does this answer the question? Well , there is a bit more to batteries than just the energy stored in it. It depends on what you are using it for.

In 2017, I went through more batteries than I care to admit. I bought batteries for my headphones, batteries for my TV remotes, batteries for my Xbox controller and for some reason, batteries for a portable radio that I don't even use. I usually go for the expensive stuff but do I have to?

Probably not.

Some incredibly astute investigative work over at Wired takes a deep dive into the 'quality' of cheap, dollar store batteries and compares them with two of the most well-known battery manufacturers - Energizer and Duracell.

Somewhat unsurprisingly, the more expensive batteries, the Duracell and Energizer, were shown to have greater power, more energy and last longer than the cheaper dollar store batteries. However, the real gold lies in the notion that the expensive batteries are not worth the extra cost.

You've been charging your smartphone wrong

  You've been charging your smartphone wrong Do you know how to keep your smartphone's battery healthy? Probably not. In fact, you've probably been hastening the death of your phone's battery with your charging habits. Charging to 100%? Charging overnight? Fully discharging before plugging in? All these common practices can shorten the usable life of your battery, according to Cadex, a company that offers devices that test smartphone and other batteries.Just how to best extend the life of batteries has been a prime topic recently, since Apple disclosed that it was slowing down iPhones with degraded batteries so the devices don't shut down unexpectedly.

Why does an energizer battery last longer than a Panasonic Battery ? The main reason one battery will last longer than another is It's been my experience that sometimes, the lesser expensive battery will provide the best performance in the long run. Does expensive or cheap batteries last longer?

If you buy the cheaper batteries , you’re paying a little bit now and then you’ll pay a little bit later. It’s thinking more short-term. If you buy the more expensive batteries , you pay more up front but they last longer. But are name-brand alkalines better than generic?

Rhett Allain suggests that when you are buying batteries, you are really just buying energy and thus, you can quantify the 'money-energy' density of the battery: The energy divided by the cost per battery.

When you analyse the three brands side-by-side, it becomes clear that the money-energy density is very similar. The more expensive batteries have more power, sure, but for the same amount of money you get more batteries in the dollar-store pack. There is one issue though: the cheaper batteries also have a lower voltage, so Allain cautions that some devices may not work as well - or nearly as long - as they would on the Energizer or Duracell batteries.

This diamond studded smartwatch costs nearly $200K

  This diamond studded smartwatch costs nearly $200K TAG Heuer’s latest creation is the world’s most expensive smartwatch to date, but its tech is standard wearable fare.TAG Heuer added 589 baguette-size diamonds (that's 23.35 carats worth of precious stone) to its latest smartwatch, which it showed off at this week's Salon International de la Haute Horlogerie Geneve. Diamonds aren't cheap, and neither is this watch: It costs 190,000 Francs, according to DroidLife, which converts to just over $197,000.

The batteries are 8x more expensive than those of Lidl, the cheapest brand. All tested batteries were Alkaline AA, had a voltage of 1.5V but none of the batteries showed the capacity on the package. One person even argued that more expensive batteries resulted in better audio quality.

Buying expensive batteries by brand name and always expecting them to be better then cheaper brands is like buying a more expensive hi fi speaker Exide and Diehard have lasted equally as long for us (6-8 years on average) The Optima batteries are a different type than the regular lead acid

In Australia, a survey by Canstar Blue of consumer satisfaction with batteries in 2017 showed that Duracell was rated the best, but that ALDI Activ Energy batteries were considered the best value for money. If we look at the price for Duracell AA batteries at somewhere like Officeworks where a 16 pack is $21.99 ($1.37 each) and compare to the ALDI batteres, where in the past they have had 20 packs go for as little as $7 (0.35c each), there is a clear discrepancy in how much you might have to dole out for your energy.

Bottom line? It's not always worth going for the more expensive batteries if you're just looking for a quick fix. Those dollar store batteries will likely work just fine.

Miners in the fast lane on electric vehicle surge .
In car factories and showrooms, and on highways and streets around the world, a quiet revolution is gathering speed. In ever-growing numbers, motorists in the world’s biggest auto markets are getting behind the wheels of electric vehicles.Experts from UBS believe that worldwide sales of electric vehicles in 2017 will be about 1 million for the first time. And they predict that in 2025, a massive 16.5 million electric vehicles will be sold - equal to almost one in every six new cars sold.But in this country the take-up has not been as fast as some countries.
