Once Again there is a good reason not to throw your damaged Li-Ion Battery Packs away. Either it is from your Laptop or your Camcorder or Digital Camera - the Cells could still work!!!
I was sick to change and recharge the Batteries of my Wireless Mouse every half day and had to find a solution for it.
Since the AAA sized Ni-Mh Batteries had not much capacity, i grabbed into my Hobby-Box and took a damaged Digital Camera Battery Pack out.
I opened it and checked the Cells - still good, only charging circuit problem!
After a look, the Cell been slightly thicker than AAA size so i had to enlarge the mouse's battery compartment. First i was unsure, because the use of two non-rechargable batteries would give a voltage of 3 and Li-Ion cells have 3,7 Volts. Nevertheless i gave it a try before i took my Dremel and it worked fine without caming any smoke out :)
The Battery Contacts had to be changed also, but that was the easiest part of all..Modified with the recycled Cell it can be used now for nearly 4 (!) days and i still have another one waiting full loaded for swap. Another plus compared to conventional rechargable batteries is the short recharging time of it.
WARNING: We have to know that Li-Ion Battery Packs have a loading circuit integrated. The Cells can only be charged with a special Li-Ion Charger who include this circuit - DON'T try to charge them with a conventional Ni-MH or even Ni-Cd Charger!!!
