Partially true. Which is why I’m required by law to state up front that I received the product from the company for review purposes. I could have simply just said “these things are great”, but I actually take the time to test each product out and report my results. And I reject a LOT more products than I accept, lol. But thank you in any case for watching. I hope you got something out of it. My sole purpose is not a simple sales pitch, but at the same time, I do run a business and I have to make decisions based on continuing to support the costs involved.
I can't find these on Amazon anymore, they have non-rechargable lithium and rechargabl NiMH. Do you know if they are still around? Also, do I really need a different charger?
Li-ion have 2000 mAh because it has 3000 mWh at 1,5 V. Flashlight probably have constant current driver and cause increase of current from Ni-Mh during discharge and thats whats leads to quicker end
If it were constant current it wouldn't get dimmer like it did... More likely the NiMH capacity is fake, 2800 is way too high to be real. They being older/used may also be a factor.
The mWh vs mAh comparison mistake along with a sponsorship does not lend itself to representing an unbiased review. Bad information so I would suggest correcting the video, we’re deleting it for reputation purposes
Good catch! You are correct. So at 1.5v, the 3000 mWh lithium would be 2000 mAh. But with my simple flashlight test, they still outlasted the NiMh for some reason. Which is why I always just use advertised numbers as a ballpark comparison. Thanks for catching my oversight!
Lithium batteries also stay at the voltage much longer than Ni-MH as Ni-MH starts dropping voltage at 50% remaining vs lithium is 15% remaining before a huge drop off and Alkaline is always decreasing voltage as it's capacity lowers
battery power and current ratings are usually market driven as they calculate their ratings with different testing setups, typically with different current draws. So one would need to run a consistent load-drain test to get proper ratings. For example, a high consistent drain will show a lower overall capacity than a pulsed low current drain. The data sheets usually show enough data to get a better feel.
I explained that the best way I could test the batteries up against each other was by draining them with a flashlight, so I did report those results. Comparing volts and such wouldn’t really be comparing apples to apples (different chemistries, etc). So I went with a more simplistic/practical test. Sorry if you didn’t find it helpful. Thanks for watching my rambling anyhow, lol.
Nimh one of the best rechargeable battery chemistries. good capacity. very safe. long useful life.
Mmm yeah OK. This wasn't a review of different batteries. It was a sponsored review of power owls

Are the lithium slightly skinnier? I find rechargeable AA doesnt work in a lot of things as they r too thick

They’re still showing in the store for me. As for the charger, I believe you’d want to use the one that comes with the lithium ones.

@@gr-lf9ul it gets dimmer because of too low input voltage and couldn't keep current.
@@mati211p yea, hence not "constant current"

The lithium says 3000mWh not mAH so the capacity is much less.

Never trust the mAh stated on batteries, it's often just a lie.
Good vid and info
Where was the "tested" portion of the video as the title suggests?? All you did was rambled about 2 batteries, not very informative
