Slow on the draw today...

Does it work well with rechargeable AAA batteries?
Does it come with a Cal certificate?

It should work ok with rehcargables:

No cal certificate, just like other Brymens.

Well, 3.55V/3= 1.18V. That is around 50% DoD of a NiMH, so not perfect.
I guess we buy a pack of alkaline then.

Or use Ni-Zn cells?

...and let them leak!  :scared:

The real question should be "Does it work with Eneloops"?

Good point. I am moving all to rechargeable batteries , no 'Eneloop' means for me  'pass by /  not to  buy'

Mi-MH is not the only rechargeable chemistry. Not buying something because it doesn't work with Eneloops is cutting off your nose to spite your face.

Ni-Zn have a nominal cell voltage of 1.6, though are 1.85-1.9 when freshly charged. I use them in my Fluke 289 with no ill effects.

Li-ion are an alternative also; you can get 1.5V AA cells, which have built in chargers, running of usb, or you can get AA sized cells with the usual 3.7V and use dummy AA's to match the voltage you want.

Personally I prefer the Ni-Zn as they are a variation on the existing and well understood nickel secondary cell. I'm still wary of using Li-ion in something I couldn't/wouldn't be happy to throw out of the window if things went wrong.
