adding to orig ?......... I have some 19.2 V
power tool (porter cable) ni-cad batteries and need to know how to 're-juvinate' them
meaning, they only last about 10min of work before needing recharging and they should last much longer than that!!!
Was wondering how to 'REMEDY' this situtation. battery memory effect comes to mind, but wanted to know if anyone out there knows how to do this, ie: re-juvinate ni-cad batteries............note: this is my 1st time here............just found out about it and we...............seems worth a try.
I'm a home inspector so i'll be looking to help out someone else with questions later.
thanks in advance for any one with the answers or suggestions. It's appreciated.

Your batteries are toast! Most likely you overcharged them.
You can attempt a few charge/discharge cycles, but more than likely you will need to replace or rebuild them. NiCd batteries like to be fully discharged before they are recharged. Heat is the great killer of these batteries. Once you cook them, they are done though, never to return......
I have a Harbor Freight store near me, and they are my supplier of batteries for rebuilding. They are always closing out batteries for some device that they no longer carry. The cells inside their units are 1700 mA sub-C cells. The last bunch I purchased were 15 for $5.00 inside of an 18V pack. That's a bargain for the cells.
You can solder the tops of the cells themselves, but not the tabs that run from the. I try to leave as many together as possible, and solder a wire on each end. I use a Weller 8200 soldering gun for this. Simply file the top of the battery slightly to clean off a good spot, apply some solder and wait until it flows into the metal.

How about adding some more detail to your question, so we know what you're asking about? Describe the problem, the size and kind of batteries, how old they are, etc, etc.
