Judging by the unevenness of the backlight in the first video, it looks like they're using two LEDs, one on either side.

If so, current consumption will be about 40mA. With a 2000mA battery that's 50 hours, not good but not awful. For most users of this class of meter it's going to last for many months.

It's nothing like the soul-destroying power consumption of those Agilent OLED meters (which also can't be used while they recharge  :palm: ).

I think that's assuming no other issues. My AN870 eats batteries whether it is off or on and to use it I typically have to replace them. It's in my "Maybe I should just throw it out?" pile. Two LED's is a good guess, it's what they've been doing this far.

Also shown in the second video (he installs them on camera).

You can clearly see there's two LEDs in the publicity shot from that page:


(You'd think they'd have photoshopped that image...  :o )

The display probably looks good in a dim basement, maybe not so much in a brightly lit office.  :popcorn:

Edit: It looks distinctly "Meh" in this other image from the same page:

I wonder how you estimate the current consumption, a meter with one led can easily be below 10mA.

You obvious have a faulty meter or use faulty batteries. The meter do not use current when the range switch is on off and uses less than 2mA in on (Backlight adds about 7mA).

Sure, but that's for reading in the dark.

This looks like the display depends on the LEDs for contrast so I'd assume they want them to be as bright as possible. They certainly look bright in the second video.

(besides, there's nothing wrong with "worst case" analysis)
