Modem Module with 6x 3.6v 2600mah 18650 Cells.

These are super easy to get to the cells. There are 2 rubber sticky pads that you can peel off. Then remove the 4 philips head screws. Then use a flat head to pop out both sides. One side will have the circuit board which is great scrap value. The other side has the 4 3.6v 2600mah LGABB41865 cells. The cells are in 2s3p configuration.

Since modem batteries are used for backup power only most of these cells have not been cycled or only cycled a few times. Modem batteries are much better for recovering cells than laptop batteries.
