Hi ALL (updated Apr 04)
Test equipment for 1.2v cell's: a principal plan.
If you have a transformer 6V AC, 15-30 Amps max, & one power thyristor
(50-100 Amps), you can make this plan for a safely recover old battery cells:
2.5# |\ |
o-------A-------|--------| >|--------------------------o 2.5#
6V AC amps | Thy |/ |\----|<|-. Diode 1n5401 |
no | nc +Tr | K-A |
o /o-----/////-------| |
/- push 10 ohm | |
| | |
1uF |----||------o\ | | +
22uF |--||------o \o----| ---------
100uF |-----||---o S1 Cell 1.2V ---
2.5# 220uF |--||--------o | -
6V AC + - |
o-------------------------------------------------------o
Mayby 12V AC ?
Set S1 for choice load time.
Push the switch to left, the thyristor gives a dc pulse to the cell.
Push the swicth to the right, the caps are disscharged...
Change the cell for the next one..

He said this is for Alkaline types but I expect it will do for Nicads as well!
Why Don't U send an interesting bul?
