Free Batteries

[W0rw]

Batteries Plus or your local computer store maybe good places to find old
battery packs. Just ask the clerk if you have an old dead LiIon Battery Pack.
i just got an old HP Laptop battery pack and 4 of the 8 cells were good.
i got 4  good Sanyo  4UR18650-2-7 LiIon batteries out and charged them and now
i have a nice external 14.4VDC supply for my KX1 at 2.3 AmpHour.
The pack weight is only 6 oz.. The cells are 2.3 " x 0.75" each.
Do not exceed the 3.700 V charging voltage, Google your mfgr's spec sheet for
maximum charging voltage.
You may have to learn how to charge them.
They have NiCad's and NiMH's too...

Most of the cells in the battery pack are already connected with Ni ribbons,
Just cut the ribbons in the middle or only pull the ribbons off of the dead
cells and all the  good ones will have welded ribbons on them and that will make
them easy to solder.
If you get a bare cell, just mechanically clean the base material and solder
away
as fast as possible.
