Can you run a 18 volt battery weed-eater on a 24 volt battery?

Q. I just got an 18 volt black and decker battery weed-eater with 3 batteries.
I have 6 24 volt batteries that came with other various black and decker tools i bought. I would like to know if it is possible to run my weed-eater off of my 24 volt batteries. They have the exact same ends just the 24 volts are taller.

If it even works will it damage either the weed-eater or the batteries?

A. it will burn up the motor.

can i use a 18 volt battery from a drill in a 18 volt circular saw?
Q. i want to get set of 18 volt cordless power tools, but i am too cheap to buy them all at once. Can i buy them from differnet brands and still expect the batteries to be interchangable?

A. if you buy both a drill and a saw that are made by the same manufacturer then usualy the batteries will be interchangable. If they are made by different companies there is virtualy no chance of being able to use the same battery for both.

If you are going to buy them both you will usualy save money buying them together. Manufacturers often sell combo packs with multipul tools that cost considerably less than buying each of the tools seperately.

If you are looking to buy 18v cordless I recomend the Skil brand. I've had a set of the Skil cordless saws and drill for about five years. Among other features the Skil circular saw takes a standard 7 1/4" blade where as most cordless saws only take 5 1/2 - 6 1/2" blades. Not only does this give it a greater cutting capacity but it also means the blades for it are more readily available, available in a much larger variety for different materials, and considerably cheaper than the smaller blades.

Can u use 18 volt lithium ion battery in a 18 volt regular battery drill?
Q. I have a De Walt XRP18 volt hammer drill with regular battery. Can I use a 18 volt lithium ion battery in that drill? can you interchange them?

How do I charge/jump start the 18 volt battery of an antique car?
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.
