II live in Bolivia where the country is flooded with crap cheap batteries, so Duracell were the best Alkaline you could buy (funny, I have bought batteries for three years now). It is very humid here, so batteries corrode quicker.

This guy doesn't understand voltage lol he says "just ignore the readings" 😂😂😂

In my experience with numerous brands of NiMH rechargeable batteries, they can be charged to about 1.44 - 1.48 volts, well above the nominal 1.2 volts. NiMH cells are also said to have a lower internal resistance than alkaline batteries, but that's where the positives end for me(and where I originally intended to end this comment). The problem is, despite the advertising, all rechargeable batteries self-discharge at a rate that makes actual usable runtime much lower than advertised. After having purchased dozens of rechargeable batteries from at least four different popular brands, I have to say that I am NOT a big fan, and unless you're a person who likes charging and recharging batteries every month, I would avoid them. I am going back to regular disposable batteries with each new purchase and rather regret my foray into rechargeables. Also, some people may not know, but rechargeable batteries will NOT last forever, or likely even ten years. Even if they can be recharged over a thousand times, they'll probably only work well for 5 - 7 years tops, so don't think having a hundred rechargeable batteries means never having to buy batteries again, it doesn't. You'll probably get between 3 - 5 years and the joy of recharging batteries every month or two if you want them to be well-charged. Personally, I don't enjoy recharging and changing batteries that often, especially not in all of my devices.

The brand reports that there battery will last over 2,000 cycles. But of course there are many variables to consider. There are actually other brands that report even more cycles. Obviously it is a very hard thing to test for.

@@Bennett_Hennessey oh okay I was just going off a few brands I know of, though I'm still sceptical they are telling the truth on on longer cycle count

This is a follow-up video I need to make. Some electronics are made for the top level of Alkaline batteries- so made to run at 1.5 volts each, and some are in series, like four together at 6 volts. It is a bad design. So, the non-lithium rechargeable batteries at ~1.3 volts, do not run such items very well. I have found this with some camera traps, a water meter. It usually happens with things with more than one battery in a series. The solution is to get Lithium recharge for such applications. But there a lot of drawbacks with lithium rechargeable batteries, so for most things you can stick with the general rechargables.

I've got 24 realy good ones from Bonai on Amazon for 30€. That was 1,25€ per unit!

Not so far. They are all running strong. So far I am really impressed how long they are lasting.

I think there is a whole building of engineers at Tesla that would disagree with your statement. I agree it wont be easy. but I think worth a try.

Right. They say it is not so much time, but the repeated charging events. But there are also better quality batteries that last longer, and charging techniques to extend the batteries life. Eneloop says there battery can be recharged 2,000 times.

Rechargeables lose noticeable chunk of ability to store a charge after HUNDREDS of cycles. That is nowhete near close to 1 cycle avaiable from non-rechargeables.

@@volodumurkalunyak4651 For phone batteries you can expect a 20% capacity reduction after just 500 cycles

This is unfortunately the design plan by the larger companies that depend on selling "throw-away" batteries. They want the public to believe there is not an alternative. Try the eneloop batteries. Many professionals have been using them for years. They are an excellent product. I just bought 8 more, because I need them for new applications.

Thanks for letting me know. I checked it looking at the video from my other channels, and it was working without a problem. Maybe something to do with your site, place, IP address- I don't know.

That is true. Good point

rechargeable batteries lose capacity and performance over time with repeated usage and charge cycles. Have you ever noticed that your phone battery struggles to hold a charge after 1 or 2 years of usage?

Eneloop pro AA (which I recommend) are online for $7 each in a four pack with tax. You can always buy cheaper ones, but cheap is cheap. I wanted to avoid stating a cheaper price and then everyone says I am not being realistic. The point is, even at $8 each, this is a far better alternative to throw-away batteries.

@@Bennett_Hennessey Disagree. Thats like saying a corvette is better than a civic, there is no practical relevance here.

No, Most batteries if taken care of properly will not leak. I have not had any problem with leaking rechargeable batteries.

Glad it was helpful!

Thank you for your comment, but I don't understand what you want to say with "don't toss them around"?

I am sure many people have also had your experience with the horrible Energizer rechargeable batteries. I think you have to accept you got scammed by them, and buy the eneloop and you will be happy.

Glad it helped

Glad you liked it

You should be able to recharge NiMH batteries in all types of NiMH battery rechargers. Lithium rechargeable require a Lithium recharge (for the smart element of knowing when to stop charging the battery). So, no, NiMH rechargable batteries do not require any special type of recharger.

I just had the crap Energizer AA battery die on me after recharging less than 15 times in 2 years. What a scam they have going.

@@Bennett_Hennessey I only buy eneloop brand only other way I’ll ever buy energizer or duracell rechargeables is if they are ever on sale like last year 4 batteries and a charger for 10 bucks I bought 6 of each gave all of away as Christmas stocking stuffers for the kids told them to only buy eneloops I have most of my family thanking me now after telling them all over and over to only buy eneloops they love em now especially now that it’s saving them all big bucks over throw always

The NiMD Rechargeable batteries are 1.3v when fully charged. That is the nature of NiMD. That is good enough for 97% of your battery needs. But stupidly some electronics systems only work on 1.5-1.4 v, which is an Alkaline battery at its peak (very wasteful on batteries). The solution in those rare cased is to get a Lithium Rechargeable AA or AAA battery. Lithium naturally will hold a 3.4 v charge, so they also come with a built in controller to give constantly 1.5 v until the battery runs out of power. This is the case for camera traps, and some items that use four batteries in series. But for most of your needs a NiMD Rechargeable battery will be fine.

A lot of money. I could never go back.

I am very happy with the Panasonic Eneloop batteries. They seem to be very well made.

Thank you. I hope more people get the message.

Fully charged NiMH rechargeable batteries are usually 1.42 v, which is perfectly fine to run 98% of battery operated instruments. If they are lower- they might be one of the many poorly made cheap rechargeable batteries. If you must have 1.5 v, than you want to get Lithium-ion rechargeable batteries.

@@Bennett_Hennessey ..those li-on are over 3.6dcv ..and the size are to big..I need AA & AAA sizes..to fit remotes..1.2v are not enough..

@@surenbono6063 There are companies that make Li-ion AA and AAA batteries. They have a controller inside to regulate the voltage at 1.5 v. I am experimenting with a few. They do not hold as much of a charge, and do not seem to be as well made as eneloop, but when you must have 1.5 volts they can work. I find the eneloop NiMH work very well for 95% of my needs

@@Bennett_Hennessey ..but that's not on my market...

@AT0M Powerex or Skyrc

I don't think so for the average consumer AA & AAA battery because the demand is a very low level of electricity over a long period= where the speed to recharge is really not that important (overnight is fine). But if they are improved to hold more energy they could work for specific applications. It looks like the general Mi-NH rechargeable is good enough for most applications that it will stay around for many decades to come.

That is good to hear. I am trying out some dubious Lithium AA batteries right now- so far holding up OK. I just wish they would not claim lies on their packaging.

As you say, entry level mirrorless- The camera should give you some awesome 4k video- but note it has a 22 mm sensor (opposed to the full 35 mm with the more expensive Canon R5 and Sony Mirrorless) and its 4k video is limited to 25 fps. If it also recorded 50 or 60 fps, that would allow you to show some amazing slow-mo nature footage. After reading an article about how smaller animals perceive time differently than larger animals (and a very frustrating period with Rainforest foraging flocks where the birds wont stay still), I have been thinking more about filming smaller animals at 60 fps, and playing the video at 30 fps. Otherwise, so many great clips are just too short. So be aware of those shortcomings, but as an entry level should be good. I strongly suggest a shotgun mic for singing birds.

Good points. I am testing some commercial Lithium batteries right now, but they do have the added circuitry which I could see adding noise. Will note that in a follow-up video. Thanks

@@Bennett_Hennessey Sweet! I just purchased a lithium ion 9v that actually holds 9.5 volts (most are in the 8v range) and I am going to test it for noise as well.

I will look into this. Recently I have been very intrigued by the fact that the ~$60k Hasselblad camera uses a Sony sensor.

Thank you. I am glad it was helpful.

Yes, I agree. One thing I have learnt through this process is that different rechargeable betters work better in different applications- such as you mention. I will follow this video up with my AA Lithuim-ion rechargeable battery test, which also has very specific applications.

Yeah I'm super skeptical about 2000 cycles, my Ladda batteries say 500 cycles in the 2450mAh ones

For both AA and AAA batteries, the best rechargeable battery for 98% of you consumer needs (SEP21) is the Eneloop- both the standard or you can get a bit more lasting power with the Eneloop Pro. These are high quality products using a well tested technology.

@@Bennett_Hennessey Thank you so much for your reply. I really appreciate your advice.
