Epic Battery

I feel mocked. No, not at all. Yeah, I'm mocked. You're an emergency guy. It's good. If there's ever a zombie apocalypse or anything, people are coming to you. Yeah. It's fine. If they can get over the fence. We're going to talk a little bit about emergency power. Part of the reason I am an emergency person is because my mom lives in hurricane country, my aunt's been through a couple of fires, I got friends in Southern California that occasionally wake up and see walls a 70 foot high flame outside their homes. --And earthquakes. And earthquakes. And hey, if you ever lived up in the mountains and you suddenly realize that you have no power, you may think you yourself, gosh, I wish I had a big battery. And basically, what we're going to create is a big battery. I love this. This is one of Anchors 12,000 milliamp-hour batteries. It's great. It's awesome. There's one of these in my bag at all times now. I can charge up to three devices si...

One thing I've noticed, is the problem surrounding smartphone batteries. Regardless of which NexGen battery technology you're using, lithium ion batteries tend to just die during the day anyway. If science can't come up with better battery technology, it can at least change how quickly we charge our batteries. USB-C for Android phones, and the lightning cable for iPhones, are now capable of delivering hours of battery life with minutes of charging. It makes life easier if you're running to meetings and don't wanna carry around battery packs. But, just how fast can we charge our phones? Not just presently, but how fast can fast charging get in the future? So, before we get into fast charging, let's take a refresher course. Volts, amps, and watts. Let's look at it like this. Volts represent the amount of electricity available in your wall outlet. The current, or amperage, is controlled using your charging brick, and is the rate at which the electricit...

Hey guys its time to do a battery charging test of the Oppo A3s it is new notch phone for Oppo it is costing around $208 In this video i am show what is a time this phone is fully charged let's the test First you noticed the battery percentage is having 30% Let's me focus This phone comes with 4230mAH battery it's mean this phone comes with 4000 mAH battery but it is not support a Fast charging. Oppo A3s Let's show you the charger.And you can see it is Oppo default charger.Let's show you the Amper rating and you can see this phone comes with a 5V with 1A charger not support a fast charging it is cable not long and you can see it is a microUSB cable.So Let's start the test I am show you the Wi-Fi,Mobile Data and another thing is Off everything is closed up in the background show you simple test nothing opened Wi-Fi,Bluetooth it is cable. So start the test it is a cable and you can see show mw the charging is start I calculate a time on my Qmobile here...

today I'm going to show you how to use a multimeter to test the battery on your car to see if it's bad Some symptoms that you could have with a bad battery or a bad alternator Is that your battery light is on the dash the engines cranking slowly or not cranking at all there's clicking when you turn the engine on But the engine doesn't start so just clicks the battery seems weak or is it dead the interior lights or a [headlights] seem weak? And stuff like that these symptoms could be a bad battery or alternator this video right [now] is going to focus on the bad battery aspect of it to See the alternator tests . [one] of the first ways you could tell if your battery's going bad is you put your key in the ignition you [turn] it to the run position and you can see Right there is the battery light That lets you know that the battery light is working most cars test the voltage of the battery through the battery light So if that blows out you won't be able t...

hello everyone today we have new lesson we going to show you how to check the life of your laptop battery it is easy you only have to follow this steps just go to command prompt {admin} it will ask you for premession in command prompt you giong to type this (powercfg -energy -output c:/energy-report.html) and wait about 60 second like what you see here on the screen, and if you get this one like this you"re good to go . you have to go c file or drive here we go you see energy report .html just open it with google chrome what you have to do is scrool down intel you see {design capacity} like what you see here now your battery is going down when you see 0 that mean your battery life is done.

A battery is a source of electrical energy, which is provided by one or more electrochemical cells of the battery after conversion of stored chemical energy. In today's life, batteries play an important part as many household and industrial appliances use batteries as their power source. Types of Batteries Batteries can be divided into two major categories, primary batteries and secondary batteries. A primary battery is a disposable kind of battery. Once used, it cannot be recharged. Secondary batteries are rechargeable batteries. Once empty, it can be recharged again. This charging and discharging can happen many times depending on the battery type. Alkaline batteries, Mercury batteries, Silver-Oxide batteries, and Zinc carbon batteries are examples of primary batteries whereas Lead-Acid batteries and Lithium batteries fall into the secondary battery's category. In this video we learn different types of battery and their advantages and disadvantages. Unfortunately there i...

You've probably heard people say that you shouldn't leave your phone plugged in overnight. Doing so depreciates your battery life and makes it age faster. You're killing your battery! I always charge my phone overnight, and I always let it reach a full 100% charge. Am I really killing my battery? Am I a murderer? I can't live with this guilt, so I called up some battery experts to find the truth. Daniel Steingart, Associate Professor at Princeton University told me that, actually: The easiest thing to do is just keep it plugged in all the time or as much as you can. - Did you hear that? I'll say it again, "as much as you can." The way he sees is it is that we all need our phones ready and charged, so we might as well keep them fully charged forever. Your phone is pretty smart, and its software recognizes when it reaches full charge, so you can't technically overcharge your battery. Charging battery at night Problem solved! But not real...

We all use lithium-ion batteries in our day-to-day lives, most commonly for things like powering mobile phones and laptop computers, but in the future we’re going to use them for a much greater range of different things. For example, we’re already seeing lithium-ion battery powered cars in the streets of London. However, as we move to more and more demanding applications, it’s crucial that we understand how these batteries can operate safely. We’ve seen recently a number of high-profile incidents reported in the press associated with lithium-ion battery failure. Quite a lot of heat is generated within these cells during failure and the failure could spread to neighbouring cells. Thankfully these events are extremely rare, so what we’re trying to do here is understand using these experiments exactly how the failure begins and what the consequences of that failure are, and hopefully by understanding this mechanism of failure we can begin to mitigate against the likelihood of these...

I'm going to talk about amps, amp-hours, watt-hours, C ratings, and other important things that you need to know when working with batteries. First I'd like to talk about a common question people have. Let's say a battery like this is capable of delivering one amp. Just because a battery (or any power source) is capable of delivering one amp, it doesn't mean that if you connect it to something it will definitely supply one amp. amp Hour and Watt Hour Explaination Voltage sources like batteries will only deliver as much current as the load needs. The amount that the load draws depends on the load. It could be a low resistance load that draws a lot of current... a high resistance load that draws barely any current... or it could be a complicated digital device like this microcontroller which draws a different amount of current depending on what it's doing. This 2Ah battery is capable of delivering over 4 amps, but with the motor I have connected to it, it...

Hi, in half an hour. I have this presentation at work sharing my ideas and findings. That's gonna blow everyone's minds. They're gonna look past my unibrow and see me for the genius I am. I'll finally get the recognition I deserve Let's do this! The car battery is dead. Well I have a few options to fix the problem. The use of AA Batteries to jump start the car I can take the transit to work. [the] Transit... riding with peasants, or even worse I can wait for somebody to show up and give me a battery boost for a jumpstart Excuse me sir, can you spare some charge? Sir, have a good day, sir? Excuse me ma'am? Or I can get smart. Can I find something at home that can help me do a jump start? What everyone has a few of at home or these aa batteries. What even an idiot knows that you can't jumpstart a car with aa batteries, but I'm gonna do it Well, the idiot is right you may need a thousand aa batteries, ten in series and hundred of those in parallel ...
