melasta 8 Count NiZn AA Rechargeable Batteries 2600mWh, 1.6V AA Battery with USB Charger for Outdoor Solar Light Flash Mouse Camera Toys MP3

I wish I would have found these NiZn rechargeable batteries a long time ago because they HAVE the Power to make my Digital Camera work at Full Capacity and while it might not be the best in the World, it's a close 2nd and for some reason it eats batteries and the only brand I been able to get to work are those gold topped ones....(the other kind are not powerful enuf I guess) but their expensive and so I have bought their rechargeable brand and they work but when I shift to Movie Mode on my Camera...it kills the batteries. So now I have these NiZn Rechargeable and they truly do have 1.6 volts (see pic) whereas the other brand only had 1.2 Volts (see Pic) which wasn't enuf JUICE to make my Camera do it's thing.NOTE: the charger uses a USB plug for Power, so you either have to plug it in to your computer, a power supply with USB ports or do like I did, find a Phone Charger and pull the USB cable out and plug the Charger in to it and then you can use a Wall Socket or a Power Supply.I have also put a pair of these in my Cable TV Remote and WOW it's a lot more responsive when I click a button...like they should be.I am very happy with this purchase and definitely recommend it, even though it would be nice if it came with it's own wall adapter.UPDATE AFTER A WEEK IN 2 DIFFERENT HIGH DRAIN DEVICES:The two of these NiZn AA's I put in my "battery black hole" of a Digital Camera are still reading 1.6 volts after 46 pictures and three 15 minute videos. (usually I get about 40 pics and one 15 minute video...The 4 of these NiZn AA's I put in my battery operated hand held screwdriver make it actually run at high speed (1st time in the 4 years I have owned it) that makes it useful finally...as before even with brand new copper tops you could almost work faster by hand...and why it's been sitting in a bottom shelf for the last 3 years...not now.I'm literally turning all my friends on to these batteries cause they really do have the "Juice" to make devices work like they were designed to.UPDATE: okay it's been 3 weeks now and the 2 batteries I put in my "battery killer" of a camera are still going strong !! I'm now up to over a 100 pics and five 15 minutes video's...definitely recommend these.

I bought these so I'd have two pairs of two batteries for my Samsung Odyssey+ controllers, and have another two pairs of two batteries for replacement. Unfortunately, only 6 or 7 of the batteries charge properly. There's at least 1-2 that aren't holding a charge at all, leaving me without any batteries to use while I'm waiting for a dead set to recharge.I bought this expecting to have 8 working batteries, because that was the exact amount I needed, but with only 6-7 working batteries, it effectively crippled my intended use for the product, and I'll have to go out and buy another set of batteries just so I can get a full set of 8 rechargeables.(UPDATE 3/31/2020):When I first bought these batteries, they would last me almost as long in my controllers as they took to charge, but in the just the first month of usage, the capacity for these batteries has dropped so low that they can only power the controllers for about 3-5 hours while taking upwards of 16 hours to charge the same 4 batteries. I've had so many times in PvP or otherwise non-pausable games where they fail on me at the worst times.I dug out some really old 1.2v Eneloop batteries and gave them a charge. They lasted for so many days on a single charge that I actually lost count, all while changing the batteries in the other controller that was still using these, maybe about 4 or 5 times. So the answer is clear, even with devices with a high power draw, 1.2v Eneloops are at least 5 times better than these 1.6v Melastas.

Got these for VR controllers as they need the higher voltage (1.6v vs 1.2v for NiMh batteries). They work, but I was expecting to use my existing "smart charger" only to find it doesn't support NiZn. It is nice that a usb charger is included, but charging 2 at a time is painfully inefficient.All in all fine product, but if you need to charge 4 or more batteries at a time, get a NiZn compatible charger.

Bought to use with a Kodak easy share but it didn’t work.

Great product , espically for vr controllers, I use them in my Samsung Odyssey plus controllers , it gives the controllers proper tracking unlike nimh batteries which are always recognized as being low battery even fully charged ! It is a must have !

Been using them for a few months now, works great with samsung odyssey+ controllers.Vastly increased run time and slightly improved tracking.

Works great. Much longer life than your typical battery. I use it in my VR headset and never looked back.

I received the batteries and the charger in good order. No failures and the charger seems to work great.

I've been using these NiZN batteries for about 6 weeks. They are very good. And they supply the extra power needed in some devices. But, 1 of the 8 that came with this order has started to display problems. It won't hold it's charge. I have checked it with a Volt meter after a charge. It's charged. But, it drains out super fast as soon as it's put to use. Not sure what's going on with it.

Use mine for VR wands because these are 1.6v compared to NiMh's 1.2v. Gives me a set to charge while I use the other set for days.

Originally I was pretty happy with these batteries, but I've found that they degraded incredibly quickly. At this point in time they're basically constantly dying and about half the original batteries are unusable.

Now that my return window has closed, two of the batteries won’t hold a charge after only 34 days. I would return if I could.
