 When it comes to AA batteries, let me tell you this much, you're splitting hairs. It doesn't have to be too complicated. Hey there, njrew22.com here with a general interest vlog. This is about electronics. This is about AA batteries today. And originally I was going to do a whole big test. I did time-lapse of four different brands of batteries. I did some middle-of-the-road AA battery alkalines, I forget which brand ever ready, I don't know, Panasonic maybe. And then I did some low-end nickel metal hydride and some high-end or advertised high-end nickel metal hydride. And then I tried something new, which I was really excited about, which was rechargeable lithium-ion AA batteries. Which I did, I kind of went into it a little bit blindly. I ended up getting, I thought these batteries were going to be super long-lasting, just as long-lasting as my best nickel metal hydride, as well as the good thing about a lithium-ion battery is that it keeps the same voltage, 1.5 volts through the entire length of the charge and then it just cuts off. Because alkalines and NIMH batteries tend to, the voltage goes down over time. But I bought these lithium-ion rechargeable batteries for pretty cheap on Amazon, but I realized that they were only 800 milliamps, which means they conked out sooner than any of the other batteries. They probably conked out sooner than heavy-duty batteries like alkaline, whatever, whatever they are. I wanted to break this down real quick here. You go on Amazon, you look at reviews. There's a million reviews about batteries, brands, Sanyo, Eneloop, Fujitsu. And then there's Tennergy, and there's Duracell, and Energizer, all these, and we're speaking specifically of nickel metal hydride batteries right now. And there's, you go on Amazon now, there's 100 new Chinese brands that have these odd names. Dlyful, and Bonnai, and the soul. It seems like they have a monkey-throwed darts at an alphabet, and that's how they spell their names. It's retarded. But you've got to be aware of one thing. Don't believe the advertised current. On nickel metal hydride batteries, it's milliamp hours, MAH. The higher the number, supposedly the longer the battery will last at its optimal voltage. You want to stay above 1.25 volts or so, 1.3 volts. They start out at about 1.45 volts and go down from there, whereas alkalines start out at like 1.6 volts and they go down. But they tend to progress or recharge, discharge faster at a more steeper slope, whereas nickel metal hydride tends to have a smoother discharge rate, slower. But whatever you do, you can't get hung up on the numbers advertised, because they never, ever, ever. They're usually 20 to 30 or 40% lower than advertised, like a 28 milliamp battery, which is considered high capacity, often don't even go above 2,000. And for a long time, let me just say this, Sanyo made a product called Eneloop, which was bought by Panasonic, and they were the king of the hill for a long time. They were close to their advertised capacity and they worked well and they didn't fail a lot. And they were made in Japan. That was the key. Japan was the key for these rechargeable batteries. They were much higher quality than the ones made in China. But since then, Panasonic, they had some weird arrangement where they sold the factory and they, whatever, they're made in China now and they're not good. Eneloop batteries now are considered not bad per se, but not like they used to be. There's two brands now that you can buy, which are Fujitsu at 1,900 milliamps, which gets about that. From what I've read, they're rated at what they say. And there's another one called PowerMax, I believe. And those are two batteries made in the same, the old Eneloop factory in Japan. And they get Mishmash ratings too. But here's another thing. You can't get hung up on the brand because you never know what batch of batteries or whether the material is no good. And whether you buy the brand in 2017, they may change by 2018. They're constantly changing their supply stream and manufacturing facilities. It's not like they're the same battery made from the same stuff every single time. So if you liked Eneloop's in the past, that's a perfect example. They're not the same anymore. Same thing with any other brand. Sometimes you get good brands, like Duracell, they've changed their factory. It's constantly shifting, so you can't get hung up on the brand. Just assume that every brand is going to mix their supply up at some given point in time and you're going to get something bad. And here's another thing to worry about or concern yourself about when it comes to the batteries. You buy 20 batteries. You should always assume that one or two are probably going to be bad. Their quality control in general stinks or they're going to stop charging after five or 10 or 20 charges. So just build that in. Also stop worrying about how many charges they claim. Some say 300 charges, some say 500, 1,000, 1,500, 2,500 charges. You can use the battery every single day for like eight years before you get to 2100 charges. So I expect them to last maybe 200, 300 charges max before they just don't either hold the amount or they just fail or hold the right amount of charge. So if you get 200 to 300 charges, any battery will end up averaging out costing less than one cent per use. That's a lot less than $2 when you buy an alkaline. So your cost savings at that point is profound. It's amazing. Anything after that is slicing like decimal points of pennies. So don't worry about it. Expect to get 200 charges max out of your batteries and stop worrying about what they say on the battery itself. So that's basically it. And as far as these lithium ion batteries, I'm kind of excited about it because each battery has its applications. If you have some sort of, I mean I don't really ever recommend buying alkaline unless you're using them for like some camera equipment. And in that case, if you, if longevity and reliability, you should buy the disposable lithium ion batteries. They're very expensive. You can actually get them pretty cheap when you buy them in bulk. If you know you're going to use them regularly, I would just buy lithium ion disposable batteries. And as far as the lithium ion rechargeables, that they're new to the market. So they're going to be expensive. They're going to be in the neighborhood of up to, I think I wrote it down here, $6 to $10 a battery. And if you can get the higher capacity ones, it would take you a lot longer to get your money back on those. But still, if you can get a thousand charges out of them last year and they fit your needs, they might, they might work. But you've got to be careful. I mean, I'm not sure, you're never going to get the length of time that you can out of a really high end nickel metal hydride battery. But again, your camera or your high draw device might require them. So I wouldn't worry about the brand. Just pick a brand, buy, and if you can get them on sale sometimes, I'll buy any brand. I'll buy Tennergy. I just bought some Bonai batteries because I got them really cheap. I think I got 2600 amp batteries for, I think, $23. So that's a little more than a dollar a battery. And that's fine. The less out of pocket you spend, sometimes the better. It stings less because especially if you spend $40 or $50 on a Loop Pro and one of them goes bad or it doesn't last as long as they say, I don't know. It's complicated. Don't split hairs. Just buy, if anything, just buy the brand name Duracell or Energize. They'll work fine for a good enough time to be a good return on investment. So that's it.
