After a few weeks living with them, my favorite is the ANENG AN860B+.

Normally I'm in the "smaller is better" camp but I definitely prefer using it over the AN8008 for some reason, ie. If both meters are within reach then the 860B+ is the one I'll grab.  :-//

YMMV

I don't have 8008 or 8002, but I prefer to take the DT830D sometimes over the AN860B+. Simply because it's smaller, I can do continuity checks faster and don't have to worry as much about the meter.
But for resistance or other measurements (other than some rough quick checks), auto ranging seems to be helpful.

My AN8008 finally shut off after running non-stop for over 16 days. I never saw the low battery indicator appear on screen. I had just checked it late yesterday afternoon and there was no low battery warning, but this morning it was dead. So it must not appear until only a few percent of battery life remains. I checked the two batteries when I took them out for recharge and they were at 1.219 and 1.225 volts. The batteries used were regular (non-eneloop type) Energizer brand NiMH rated 850 mAH.

stj:
that depends on how much you hacked it,
normally you only get the low-battery warning for 6 seconds - then it shuts off.

options are, warning 1-15 seconds then off, or warnings but no power-off.
atleast i think it's that - maybe it suppresses the warning too - i'v not tried setting that to 0.

rdl:
What? You don't get any warning until just seconds before it goes dead? That's useless. My other meters will run for hours with the low battery indicator on.

It's going to depend on the battery type.

All batteries have a moment where the voltage suddenly falls off a cliff. If your battery type does this above the cutoff voltage of the meter then you won't get much warning.

Somebody with a fancy power supply could determine the cutoff voltage...  :popcorn:
