Battery conversion


Iím not sure if this is the right forum for this question, but maybe someone can steer me in the right direction.
I have a tool that plugs into my car lighter and I would like to make it more portable, can I wire the tool to a rechargeable dry cell battery like you would find in a 12 volt hand tool (ie: power drill)
Thanks

It's still 12 volts. And I don't think there is a major difference between wet and dry cell. but I'm not sure. If not then just stripping the wires and clipping them to the rechargeable battery should work... I think. But if any body knows for sure I sure would like to hear from you.

Thanks

Wire it up. A battery is much cleaner power than a running car, which has voltage spikes.
You need to figure how many amp-hours you want, though.

Without knowing exactly what the tool is or the specs on it, you will only get a generic answer.

Having said that, IF the battery you want to use can supply the current required by the tool at 12 V, then yes it will work, making sure the polarity is correct. In other words, a car battery can supply a lot more current at 12 V than a camera battery at 12 V.
