I want to run my 12 volt power tools ( ridgid ) using a 12 volt lead acid battery

I have been doing this for years and I finally found this line of tools that is small and compact and the battery fits in the handle and it has tons of power  the lithium ion 12 v ridgid drill and job max line. I tried to wire up the tools contacts to the small lead acid batteries I normally use and even a full size car battery but it failed to power tool because there is this small contact that the tool is requiring which the lithium battery has but obviously the lead acid does not.  I do this for heavy duty use such as continual sawing and sanding and things like that.  any suggestions I really need to make this work as I run a mobile business.  I am looking for a solution to over riding the need for that extra contact and I am fully aware that I will void the warranty as many of you may be thinking. Please help

multi voltage project for sons project

Hello I was wondering if someone can help us. We are building a school project that has 3 different lights on it. what we are trying to do is have everything work off one 12 volt plug in transformer. What we have is a 12 volt dc transformer for 2 led drivers and a 6 volt ac transformer for a turning table. We want it all to work off one plug-in style transformer. How can we do this and conceal the components in the base. Please help us. Thanks for any help.

12 Volt Gas Generator

I am looking to building a 12 volt generator from an alternator. I want it to have a car battery (or a deep cycle battery if it's easy to integrate) for quiet operation. I want the output to equal that of a 12V car plug socket so I can easily invert it to 110 volt AC. the engine will need to be small as possible without stalling on high demand. I guess it would have to have the same circuitry of a cars main power circuit. So, can someone give me a few tips on making this? And most importantly, a schematic. I can't seem to find a basic car circuit.

Am I looking for trouble wiring them directly without any resistors?  I really don't want to get into resistors, etc. if possible. Thanks in advance for any thoughts and suggestions.

I just purchased a set of running boards off of a 2011 f150. they are electronic and i need to wire them up to a set of relays. what i am trying to do is to make it so that when the door is open it triggers the relay and powers the motors causing the running boards to open up, easy enough. but the problem i am running into is that when the door is closed and the door ajar switch is no longer sending a signal, i need the relay to then reverse the polarity so that the motor will then spin the opposite direction causing the running boards to fold back up. the motors on the running boards do have built in stops so i dont have to worry about leaving power to them. i am also finding out if the door ajar switch on my 2004 chevy silverado uses a positve trigger or a ground trigger. any help i can get would be much appriciated. thanks

Run a laptop off of 12 volts safe?

My laptop battery is 10.8 volts. The charger I assume inverts ac to dc current to charge the battery. I also assume that if there are any ac voltage requirements  in the laptop it must have an internal invertor from dc back to ac. The charger input is 110-240volts 1.7 amps. The output is 18.5 volts 3.5 amps. My question is why can't a 12 volt source like a jumper box be used to run the laptop, when the battery is low, through the port that the charger is plugged in when charging the battery. My thinking is that the battery being 10.8 volts dc is charged with up to 18.5 voltsdc then it would be safe to plug in a 12 volt battery source. Thanks for your time!

I am on the attempt of making small portable infinity mirrors and coaster seem like the best idea for them. i wired it all good and i am done now however i appear to have a problem Step 1: Infinity Coaster everything works well until it has been left on for 2 mins. even when i turn off the lights, the batteries get super hot. They are cheap dollar store AA batteries but almost too hot to touch even when it is turned off. i figured maybe i have a short somewhere but i cannot find one with the multimeter. is it just that i have too much amperage for too little of an LED strip? https://www.youtube.com/watch?v=fvYCstmnIfY they stopped turning on the lights when they got hot but i tried again to shoot this video clip and they worked pretty good. A little slow to light up still so some of the juice is gone i imagine. if you know these strips give me a clue. if i find out the problem, i can make a solution and make another instructable on how its made with # 2. it is Christmas after all and somebody needs a coaster for their egg-nog.  these pics arent great let me know if you wanna see wiring more clearely
