3 BAK 18650 2200MAH CELLS IN SMPCM1 MODEM BATTERIES
You get 3 cells in a pack for just $1.20 cents! 40 CENTS PER CELL!
Modem batteries are only cycled when a home loses power, which is very rare in the US. That is why they test so good compared to salvaging cells from laptops.
These are a great source of genuine BAK 2200mah cells. BAK is a relatively good brand, and these cells typically test very well and have a lot of life left in them.
You can pry the seam with a pair of wire cutters to get the cells out.
Since these have been in storage uncharged for shipping standards it's possible some will have low voltage, but they will wake up for sure. Out of thousands we have tested there were only a few bad cells.
