Thank you mad777I have 3 Liikotas lii500 and 1 Zanfare C4.
One lii500 died, another has one bay that sometimes needs battery reinserted to start, and the other unit is fine. No problems yet with the C4.
Thank you mad777
What about accuracy between both?
I need to know which one will give me more accurate capacity test?
HKJ states that: "The mAh display is a bit on the high side."
Thanks chrisshttps://lygte-info.dk/review/Review Charger Zanflare C4 UK.html
There's the test.

This is why i am confused and cant decide which one is more accurate
Thanks chriss
But as i said i read both reviews by hkj
On the zanflare c4 it was saying what you quate now that the display of the mah is on the high side
And for the liitokala lii500 he said that this charger dont fill the battery completely
This is why i am confused and cant decide which one is more accurate
It will be great if hkj will answer to my questions
To better answer your question you should tell us what accuracy you need, and especially why you need it, e.g. do you need absolute or only relative accuracy? Are you planning to post reviews of many batteries (comparing absolute numbers) or do you plan to use capacity only to track battery health (so absolute numbers are not as important, i.e. here one is more interested in the capacity lost - a relative number). Some chargers may have poor absolute accuracy (e.g. calibration offset) but those will cancel out when you take differences, so their relative accuracy may still be good - and that's primarily what you need for tracking health.
I trust HKJ and certainly reading slightly high could be a possibility. However I have noticed with the C4 that occasionally I will get some low readings after a Nor test with Eneloop AA.https://lygte-info.dk/review/Review Charger Zanflare C4 UK.html

I just want a charger that will show me reasonable Mah capacity of my brand new eneloops
I want to buy cheap analyzing charger for testing eneloop only
I read hkj review of both but i couldn't deside which one is more accurate?
Who will give me the closest mah capacity of the battery in nor test?
Hi gadits,
measuring mAh accurately is tricky, because it depends on so many factors. Like how deep you discharge the cell, how big is the discharge current, do you integrate the variable discharge current over time, or just multiply the discharge time with constant discharge current?
If you pick 0.9V then is it 0.9V under load or 0.9V open circuit? And 0.9V in winter will be reached sooner than 0.9V in summer as the cell voltage depends on temperature...
Also, cells with high internal resistance will reach 0.9V under load much quicker, leaving plenty of undischarged mAh in the cell, but it will give you the more practical "usable" capacity of the cell. Discharging to 0.9V open circuit will give you the "total" capacity which you will never be able to use. What are you more interested in, the smaller "usable" or the bigger "total" capacity?
And then, assuming 2 cells, one brand new Eneloop with low internal resistance around 50mOhm, and one worn down Eneloop Pro with high internal resistance around 800 mOhm. Both read 1850 mAh, are they equivalent? Not at all. The internal resistance is also an important factor to tell the state of health of a cell. So how you measure internal resistance most accurately? The answer is - it does not matter
Get an analyzing charger that shows a rough estimate of the cell's capacity and a rough estimate of its internal resistance. Lii500 is not able to measure internal resistance on NiMH cells, so get the Zanflare C4.
