Typical results:
1880mAh @0.5A-81% of claimed capacity
1700mAh @1.0A-73%of claimed capacity
1575mAh @1.5A-68%of claimed capacity
1370mAh @2.0A-59%of claimed capacity
THIS MODEL DOES HAVE A VOLTAGE STEP DOWN.
It drops to ~1.1v for around 480mAh.
This allows SOME devices to notify the user that the voltage has dropped instead of cutting off abruptly like most of these kind of batteries.
MUCH longer time spent at 1.1v, at the expense of less time spent at 1.5v.
Voltage sensitive devices will see less capacity.
If you read the 3* reviews you'll see some people are getting what appear to be defective batteries. All mine work.....so far. Long term reliability and self-discharge are unknown.
SinceHoly 3500mWh are decent getting ~85-90% of claimed at 0.5A. Short time used. No idea of long term reliability.
Dracutum 3000mWh.- on a percentage of claimed capacity this is one of the best ones I have reaching 90-95% at 0.5A draw. They sustain 70-73% at 2.5A which is pretty decent.
The Dracutum ALSO HAVE VOLTAGE DROP, to 1.1v. BUT, they only do that for ~50mAh, so there is a BRIEF notification window of low voltage, but little loss of working capacity. This is the first brand that I've owned that does this.
ALL of them were bought on some kind of special, usually ~ $2-2.50/cell. I would not buy these for $4-5/cell but I really don't NEED any of these, NiMh are fine for me most of the time.
I don't have a door lock or critter cam. Those things have an entirely different demand and usually DON'T do well on NiMh, or alkaline. So those folks end up with lithium primary like $2-2.50/battery for disposable.
For excellent rechargeable lithium AA, and willing to pay the price, look at the Xtar brand.
(Note-Cicnod and JWWYJ are both not too good. Imren are OK but only if bought cheaply.
If you are one of those people that HAS to have USB-direct charging, you WILL give up some capacity fo it. Not much room in that tiny can for chemicals AND electronics). I have not found any brand in AAA size that is even decent except Tenavolt. Just too tiny and the manufacturers routinely mess this up by making them USB-direct charge. Stupid. .

Yes, those are 2500mwh but actual discharge tests were lower @ 1500-1570mah at a 100ma draw rate.
