Actually I'd rather not. The 681 has a very very similar lcd, so my guess is that the difference in battery use is epsilon at best. And the 681 has (on the paper) worse specs (like 1v resolution only).

I agree it is not a TFT but a reverse LCD. However, you are forgetting that LCD uses the external light to produce the characters, while the reverse LCD keeps the backlight constantly on. In my experience with conventional sized screen multimeters, this alone accounts for five or six times higher power consumption than a regular LCD. In this particular model I would expect more given the larger size of the screen.

Because that's what people are now used to. At least the younger generations  ::)
I mean, alkaline is so 20th ! >:D

There is a point in having a rechargeable DMM and ditching batteries. In certain countries, batteries are horrendously expensive and replacing them can be a cause for concern. Naturally, a regular DMM such as the proposed AN870 would keep its batteries for quite some time before needing replacement.

However, the younger generations indeed are used to the charging process of electronic gadgets and to me that is unfortunate, but such is life.

AN870 or even AN8008 are more accurate in this price range.

I'm pretty sure it's not extraordinary. It's more like is it good enough ?
I already own an AN8009. It's globally fine, albeit too small/light and slow. Yes, i know I can solder some too-small-for-me smd capacitors to improve the noise and help it go faster.

BrokenYugo:
USB charging is probably sketchy isolation at best, directly connected to the common jack at worst.

Fungus:
Can you use it while it's charging? I hope not.

The usb "shield" at least dot not seem to be connected to common/ground.

Yes, it starts while charging, and it seems exactly the same than while not charging.
