9.6V Rechargable question

[kevinthenerd]

Someone gave me a 9.6V cordless Ryobi drill for free. The only catch was that they lost the cord to the charger. What voltage should I run to a 9.6V NiCd battery to charge it? How would the voltages differ if I intended to charge it rapidly or charge it over night?

(I have a universal AC adapter that I've been using for a keyboard ever since I lost its own adapter, so I can choose from 3, 4.5, 6, 7.5, 9, or 12 volts. If it's really important, I can probably make something in a different voltage range.)

I have it sitting on 9V right now. Can I ruin it by attempting to charge it too slowly?

go to homedepot or something, and look at the chargers.

Have a look at their site. Looks like they got manuals and parts lists available.

Take out the battery and just use your car battery, it will run a little faster and a little hotter but you will never need to charge it again.

but then what will I use to power my welder?

Does anyone think that 12V will kill it?

Maybe I shouldn't have left it on 9V over night and forgotten about it. Big oops on that one.

Are you talking about charging the battery directly, or the power cord for the charger? If you're trying to charge the battery without the charger, don't. You can cause a fire 9.6v is fairly common pack voltage- go to radio shack and pick up a charger for a 9.6v R/C car pack. That will do the job. If you can wait, buy a Ryobi charger online.

I'm talking about using a universal adapter on the charger.

$25 for the charger? I got the drill for free. I can't justify that. If I break the batteries, I break the batteries. I'm not out anything. I was just hoping that technical data was available.

Maybe I should ask the seller of that charger on ebay what the plug says the voltage output is.
