- In this video, I will show you how to measure internal resistance, battery capacity to determine which old battery is still good or just indicator fake battery. Remove defective batteries to avoid damaging when building the battery pack such as e-bike, power wall, power bank ... in a cheap way!
Internal Resistance Ohm
below 35mR - new 95~ 100% battery life
below 50mR - 90~95% battery life
50~100mR - 80% battery life
100~150mR - 50%~60% battery life
above 200mR - Recycling them in the proper channels conserves resources
Buy Liitokala: s.click.aliexp...
Liitokala Lii-500s at amazon: amzn.to/3b6tGVg
Lii-500S is a newest !!
Uh... bit confused... when you say "mR" do you mean mOhms? If that is the case, then I found my problem... battery for my mouse is measuring .277 ohms.... or 277mOhms
Cell 2 was 3.69v surely this cell is bad should it not be 4.20 after being fully charged by a Nor test?
Thank's Bro
i have LiitoKala Lii-500 when is better to measuring internal resistance ,when is full charged or when is discharged ? it is very different value like 10-90
I agree I was about to ask the same question when’s the best time to to take internal resistance? At nominal voltage I’ve gotten 100-125 and fully charged ive gotten 15-55 ir ??
Li500 V2 can not measure discharge capacity. She's not worth to buy instead of V1.
Also you need to know, that if the cell has less than 2.3V, it doesn't charge it. It will charge them up to ~2V and stops, thinking that this is NiMH battery. To rescue cells that were 1V or less, I bought Xtar charger. It's worse than Li500, that's why I use it as a supported charger, but I recommend such a duo.
so this one is Li500 v2 or v1 can you tell me
@@diablo6520 The charger in the video measures the capacity. So it is Lii500 😉
"Upgraded version" is Lii500S, which cannot correctly measure the capacity of the cells
Measurements of internal resistance in this charger are not reliable, the results are badly deviated
Agree, this is cheap charger, not professional IR measure tool
@@Laamlee-yt I have four such chargers :), I like them very much but IR measurement is a terrible mistake should be either corrected or removed from this charger
Work great for comparison test of a large group of used or new 18650s, actual value may not match spec sheet but for comparison the values are consistent
apart from this LiitoKala Lii500s battery analyser is there any other battery analyser that has NOR TEST and can carry more than 4 - 6 cells, please if there is any what is the name?

Very helpful Video, Thank you. Starting my battery extraction and testing now.
Hello is NOR test same as GRADING mode in some Chargers?
Any one know when is the best time to take the internal resistance. When the voltage is at nominal or lower I’ve gotten between 90-125 and fully charged it’s 15-50 IR ??
Between normal and full state because thats the times you use them in your machine and yu dont use them when low battery
Dont use above 90 in packs
Hello guys, Anyone can explain why is this test called NOR? Is there a logic behind like NOR gate or?
NOR = NORMAL
loose that music!
When I run norm mode it takes like 12 hours to complete the test for four cells.
pro trick: you can watch movies on flixzone. Me and my gf have been using it for watching loads of movies recently.
@Cairo Alessandro Yea, been watching on Flixzone for months myself =)
where can i find lishen battery, is it good
I bought at local store. Seem it's doesn't have any aliexpress or bangood link, alibaba and taobao has it
@@Laamlee-yt Thank you
, will check there
You"re welcome ❤
