As a rule of thumb, any laptop battery for less than $50 is recycled crap.
There are companies who mix-and-match recycled cells and combine them into Ebay batteries out there. Beyond the explosion risk innate to Li-Ion, you're going to get bad battery life with these recycled cells in the very best case.
The cheapest "legitimate" laptop batteries I've found come in the ~$80 mark.
-------------
A good and proper 18650 cell costs $7.50 alone, and you'll need six of them to build a laptop battery.
That's $45 for 6x proper cells straight from the manufacturer. Plus labor, plus all the other parts of the laptop battery (chassis, protection circuit, etc. etc.). Anyone selling for less than $50 is straight up recycled mix-and-match junk. Its the only way you get to $20.
And before you go look up cheaper cells: Ultrafire cells are recycled junk. So ignore all of those listings. Its best to stick with Panasonic / Samsung / other name brands.
