Only logged in customers who have purchased this product may leave a review.
Old cells were 2000mah and only held about 800mah.
I tested thse cells with a discharge current of 1a, so 1/3c and they hold almost 3400mah! (4.20v to 2.90v) see photos.
Most capacity tests go only to 3.00v, but then, they also use 1/20c. So capacity is as seller states.
The bms is still adjusting itself after 5 full charge-discharge cycles in the laptop and the displayed usable capacity grows.
Longevity and long term reliability ... w'll see
So ordered more and will add another review if those are ok
Maybe need to buy 100-200pcs
Also very fast delivery!
I am satisfied with the seller, in terms of quality I will write in addition to the review, I order not for the first time, while there were no complaints.
