Question: how many cells does a lithium ion battery have?
Answer: For a lithium-ion cell, this is calculated at 0.3 times the rated capacity (in ampere-hours). Example: A 2Ah 18650 Li-ion cell has 0.6 grams of lithium content. On a typical 60 Wh laptop battery with 8 cells (4 in series and 2 in parallel), this adds up to 4.8g.
