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.

Last week, we reported on a leaked Google Pixel 3 XL screen protector that had an iPhone X-esque notch on top. Now, an alleged photo of the actual phone has appeared online - and that telltale little rectangle is plain as day. We ' re all going to have to get used to notches - they're hear to stay.

Clearly, these cheaper batteries are not nearly as good as the more expensive ones. Well , there is a bit more to batteries than just the energy stored in it. It depends on what you are using it for. Suppose that I was using these batteries for a flashlight.

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.

Good batteries aren't cheap or maybe they are . Putting that notion to the test is Martin Cheung, who recently published a video in which he tests the recycle speeds of inexpensive rechargeable IKEA LADDA batteries against more expensive Panasonic Eneloop Pro batteries using Godox TT685

Are lithium batteries better than lead-acid batteries ? Will batteries be polluted or not? Typically they go in price fro expensive to cheap , to ultra- cheap . I would personalyy stay away from ultra cheap , however , in testing, the big store house brands tested as well as the national brands.

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.

Italy is drawing Samsung into Apple's battery battles

  Italy is drawing Samsung into Apple's battery battles Samsung denies it's slowing down phones, as it faces an investigation from Italian officials. Officials are also looking into Apple's behavior.This is the first time Samsung has faced this accusation.

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?

However, a cheaper battery brand that I really like is the Kirkland (Costco) brand. They're a really good deal and last a long time. Energizer for example is really expensive here in my country but it’s worth it though because its power works longer than those that are cheaper .

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.
