I have been pretty happy with my YR1035+. I chose it because it displays more digits. It also has a backlit display and a rechargeable battery inside. I had it for a couple of months, but I only charged it once.
It displays up to 4 decimal places in voltages for Li-Ion batteries, 2 decimal places for internal resistance in mOhm range. I cannot tell how accurate the numbers are, but the numbers are at least very consistent when I measure the same battery multiple times.
