Batteries: difference between LiIon00 and LiIon20

#1 Post by RealBlackStuff » Fri Mar 30, 2018 10:26 am

Can anybody tell me what the difference is between LiIon00 and LiIon20 ?
Some batteries marked with LiIon20 seem to be more powerful, others maybe not?

All below are Lenovo 6-cell 68+ that look the same and fit in X240/X250/X260/T440/T450/T460/T560 and probably others.
45N1130 / 45N1735, Nom. 10.8V 4.4Ah 48Wh, Min. 4100 mAh, LiIon00 - Average
45N1128 / 45N1734, Nom. 10.8V 4.4Ah 48Wh, Min. 3930 mAh, LiIon20 - Slightly weaker
45N1134 / 45N1777, Nom. 10.8V 6.6Ah 72Wh, Min. 6080 mAh, LiIon20 - Definitely stronger

I also noticed it once, and now that you asked, it prompted me to do some research.

It appears that these are just Japanese recycling markings, and they vary depending on the most prominent metal in the anode. Explanation:

Thank you for bringing this up, and putting it to rest. :)

Maybe different manufacturers have different recycling ratings?
Thinkpad4by3's Law of the Universe.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.
