1.8v is similar to the single use lithium AAs made by energizer. 1.6 is similar to a new disposable AA. These would be great for stuff that needs a full 3V minimum. They should be charged immediately after they are discharged, the issue is that they form dendrites like NiCd cells do. ❤

[frankcastillo]

Thanks for explaining the differences between this and the Li-ion AA. The price difference is actually huge if you buy a lot of these.

One thing to keep in mind with the MWH vs MAH rating is that the runtime in an actual device depends very much on how the device is regulating its input voltage. Boost-buck converters and switching-style regulators (used in many devices that have more complex electronics inside) will vary the amount of current they draw from the battery based on the voltage. If you put a higher voltage battery like an NiZN in there, they will draw less current than they would off of a lower-voltage NiMH. In these kinds of devices, the runtime might actually be very similar between these NiZNs and more traditional NiMH batteries.

On the other hand, devices like flashlights, razors, many toys, AA powered fans, and other such devices usually do not use these kinds of switching voltage regulators internally, and won't last as long on lower-mah NiZN batteries. If the device you are using performs noticeably worse on older batteries, this is usually a giveaway that it is this kind of device. Flashlights, for example, will shine brighter with NiZNs, but they will die faster.

NiZNs are really good for devices that tend to perform worse on regular rechargeables. In these kinds of devices, NiZNs are a great way to use rechargeables without sacrificing operating performance, but the runtime of the device will be a little bit less than that of a typical NiMH battery in these kinds of devices that are sensitive to input voltage like this. In most cases, I think that NiMH batteries are a better general all-purpose solution, but NiZNs are definitely useful for more niche use cases where higher voltage is necessary. They're good to have on hand in my opinion.

The reason they are using mwh is because mah doesn't matter when the voltage is different. mwh is more accurate when comparing batteries of different chemistries. For example, those lithium batteries when measured mah, you need to use the 3.6v nominal voltage for the amount of energy in the battery. These lithium AA batteries are a lithium battery with a DC-DC voltage regulator. So if you compare the MAH rating, it will appear much lower than it is because a 2000mah 3.6v cell has more energy than a 2000mah 1.2v cell.

Good to know there are lots of options

[Przemo-c]

Actually mWh rating is a better comparator for capacity when voltages differ.

Nickel Zinc was originally used by Edison for headlamps used in mineshafts 100+ years ago. Fully recyclable. Works well in high heat environments.

[vanlifefpv]

Interesting options for AA batteries. Stuff no one else is covering.

[johnk]

I heard there was an updated battery to the old carbon-zinc batteries. Seems like a nice replacement especially since they maintain their output consistently and have a better price than the other newer alternative batteries. Thanks for the review.

[tarstarkusz]

It's not a new chemistry, but improvements have allowed them to last longer.
How is the self-discharge of these cells? Can they sit around charged for a year or more like the low self discharge NIMH?

[jlarson]

Great review and comparison video. Definitely a good value especially when compared to Li-ion AA batteries and charger. I wanted to order the xtar set but price was a bit to much for me. The price of these batteries and charger is a bit more palatable, they're on the way. My rc 4x4 controller eats batteries, these will help save money in the long run. 👍😎

[medrone]

Cool to hear about batteries that save the environment & some bucks $$$! Do NiCad batteries work okay in transmitters or are they a no, no?

[thehuguenot]

I've been using nizn for years. They are great for thigs like trimmers, drills, stuff where it does hurt to have a few more RPMs. But unfortunately they only last a few months because they are cheapos from China. And semi conductor companies like Panasonic and Sony didn't make them. Hopefully EBL will be different.

[MCsCreations]

Pretty interesting batteries indeed! Great review, Albert! 😃
I've heard about this chemistry before, I just don't remember where. 😬
Anyway, stay safe there with your family! 🖖😊

[obliviousmode]

What’s the comparison vs the red rechargeable lithium ion battery that EBL offers? I see the Red one is more expensive.

[spiculum]

Thanks for the video. mAh rating is not energy capacity rating, its just current drain over 20 hours. mWh is energy capacity rating and is related to volts times amps delivery. Therefore, a 1000mAh 1.2v battery will have 1200mWh of energy in it but a 1000mAh 1.6v battery will have 1600mWh of energy in it.

[zevindd]

These might be nice for old stuff that was designed for Ni-Cd with the slightly higher voltage,

[kristianmuotka]

Interesting with more alternatives. Guess well see how this type of chemestry would hold up over time... 3 of em could power a whoop! Mabie nott the best.. ;-)

[kevinkearney]

How do I convert mAh to mWh (and the other way).
