Bring Dead Ni-Cad Batteries Back To Life

Step 5: Add the battery holder an the switch

Then we need to solder the battery holder and the high power switch together with the black capacitor.

Solder the black wire of the battery holder to the lead of the capacitor that is the closest to the grey stripe.

Solder a piece of wire to the other lead of the capacitor.

Then solder the push-button switch to the red wire of the battery holder and the other wire.


Also, the battery holder you just added, that is where you put the dead Ni-Cad battery to zap them.

So the negative of the cap goes to the negative of the battery and same with positive?

[chriskarr]

So I take it the stripe on capacitors means that it is the negative lead?

[russtang]

On electrolytic capacitors (usually tubular can shaped) the stripe denotes the negative side. On most, if not all Tantalum caps (usually yellow, rectangular with brown stripe , the stripe marks the positive side.

yes.

I thought so, but I wasn't 100% on that. Thank you.
