Q. It's a 1947 Cadillac, I was supposed to be starting it up periodically for the owner, but there's not enough juice. Can I just use a regular 12 volt starting pack, or just jump it off of my truck like a 12 volt battery, or are my options more limited?
A. First, a 47 Caddy has a 6-volt system not 18 volts. And, no, you cannot jump it with a 12 volt battery without risking serious damage to hard to find parts. Purchase a battery charger with a 6/12 switching system and use it to keep the battery charged.
Can I convert an 18 volt battery miter saw to an AC piece of equipment and if so how?
Q. I have an 18 volt, 8.25" Ryobi miter saw. I would like to eliminate the battery and be able to run the saw from a continous power source. The batteries wear out to quickly, but the saw is perfect.
A. it is possible to do this ...all you would need is a transformer to lower the voltage from 110 volts to 18 volts and a bridge rectifier to change the ac to dc....a bridge rectifier only costs about 30 bucks and a transformer could cost anywhere from 10 to 50 bucks depending on the va of the transformer....to figure the va of the transformer you would multiply the volts 18 times the max amps listed on the data plate of the drill...for example if the drills max amps was 10 amps at 18 volts that would be 180 va(volt amps)....you could mount all of this in a box with a cord to plug into a wall outlet and a cord to go from the drill back to the transformer box....the total cost for something like this plus paying an electrician to wire it all up for you would probably be in the 150 dolllar range....i could build this myself...but it would just be cheaper to buy a standard 110 volt miter saw to begin with.....but on the other hand if you have a lot of 18 volt tools then this could be the way to go as you could adapt the battery itself by removing the battery and using the shell to allow you to change it from one tool to another as long as they all used the same type battery...this would last indefinitely as long as it was built to withstand the max amp load of your most powerful tool ....
how to repair dead power tool batteries?
Q. I have an 18 volt battery from a milwaukee cordless drill that is dead. Does any one know how to repair them?
A. Normally when the rechargeable battery pack won't recharge anymore people just go and buy a whole new battery pack.
If you really want to repair the pack, you could take the battery pack apart then take it to a battery store that specializes in selling just batteries. All the pack consists of is several round (cylindrical) batteries (cells) that are hooked together via wiring. Normally the wiring is welded to the battery ends. If you take the opened up battery pack to the battery store they can replace the battery cells and wire the new ones together like they should be. It may cost less than a new battery pack, but I'm not sure. I replaced the batteries in my rechargeable shaver once when I was tight on money and my shaver gave up the ghost. It cost me $6 to replace the rechargeable batteries compared to $40 for a new rechargeable electric shaver.

What do i set my universal AC adapter on to charge a 18 volt drill battery?
Q. i have a cheap 18 volt drill its red and no name on it. i have the original charger box but its missing the power cord. i have a universal ac adapter but i dont know what to set the volts on? its 3-12 volt 600ma please help.
A. ain't happening.
you need 18v. no more, no less.
the amperes need to meet or exceed the rating on the battery. in charge state it will only draw what it needs.
so you need an 18v charger that can deliver at least the ma rating on the battery.
or,
go to a thrift/second hand store. they usually have a box of misc power adapters. find one that meets your needs and buy a universal adapter for that, or splice in some wires if it physically won't fit.
cheers!
