I don't see a 12 pack option. 2/4/8/16 are available but not 12. How to reproduce this?

12 pack option available again as of 4PM PST. 2 slot charging is a bit of a let down though as my primary application takes 4 batteries at a time.

So what's a good use case for these, Xbox controllers or are they better for super low current applications like remote controls? An electric door lock might be a good one (alkalines usually last me about a year).
I have a bunch of garden irrigators that will not work well, or too long, with Duraloop rechargebles rated at 1.2V, they need 1.5V. Currently I am forced to use non-rechargeables that also last me about a year, longer if at the end of the warm season I remove them from devices.

This kit has potential, however reviews show quality of recharging is iffy, and having only one charger (designed for only two batteries to boot) can be a serious bottleneck, especially if it goes bad, since these batteries are not compatible with smart charges for the 1.2V rechargeables.

Props for the use of mWh instead of the misleading mAh though.

What are these percentages? I originally assumed it's the capacity relative to advertised, but stated capacity is 3600mWh and these values are closer to 70% of that, not 90%.

Also, thanks for using mWh, mAh makes it difficult to compare different battery chemistries.
% of "claimed" mAh. Didn't do the math on mWh.
Most folks want to see mAh. Historically I've worked with NiMh so I'm pretty used to using that 'tool/measurement', so I use it.
Technically, for this kind of chemistry mWh is correct. I could have used that as my device will measure it but there's enough bitching about mAh vs. mWh.....AND, since the electronics ARE THERE for voltage conversion mWh are not being measured directly.

Yes; 99% of this market reports in mwh, not mah.

Perhaps coloring by numbers suits you best.
80% of stats are made up or in this case 100% of stats from trolls like urself.
perhaps layoff off numbers in general suits you best

Simply divide 3600mW(Watt)h by 1.5v since a Watt is just A(Amperage) * v(volts).
This gives us 2400mAh.
