I just got back from a computer recycling center and picked up 120lbs of laptop batteries. Now unlike before, I decided to do something interesting... I decided to bin my laptop batteries.
Here was the process. I would read the side of the laptop battery and run some calculations to make sure each cell in the laptop battery was at least 2500mah. For example, I got a dell 97wh 9 cell laptop battery and using some math, I determined it likely has 2800mah cells inside. Those laptop batteries I set into my "high grade" bin.
I then sorted the laptop batteries by the ones that likely had cells between 2000-2500mah. Those laptop batteries went into a second bin I will call the "mid grade" bin.
Then finally we get to the low grade bin. These laptop batteries were under 2000mah calculated cell capacity. Since my standard is 2000mah, I am not even going to usethese. I am going to throw them up on ebay and get some cash back.
The whole binning process took an hour to do 150 laptop batteries. but I think this was quite worth it. Now I can turn all my attention to the very best cells with only the best capacity, move to the mid grade bin when I run out of the good ones, then move to the "low grade" bin and sell those on ebay to get some money back.
What do you guys think of doing this? For me, it was absolutely worth doing. But what do you think?
