Wow, my head is spinning after watching the video. very confusing to me.

Sounds like the real deal if it works. I don't use my battery tools much except my drill motor and driver. The saws and other assorted ones I only use if I go on the road for a job. I must have a half dozen chargers all plugged in. I can see the advantage, but looks like a person needs a different adapter for each brand?

my friend who taught me how to install car stereos in the 1970s recently did something in the same spirit.

His 90 year old mom still enjoyed using her 40 year old electric Black&Decker lawnmower, but he was concerned she would run over the cord. Upon disassembly, he noticed the motor is actually a DC style.

Voila, he made up a battery pack holder and plug and now she has a cordless lawnmower that runs on a couple of DeWalt batteries that can be recharged easily.

I bought an adapter for my 18v DeWalt tools so it could use the new, 20v LI batteries. Unhappily, it is nearly impossible to remove the adapter from the tool, and the LI battery is barely able to hold a charge. So I've purchased new 18v batteries and will use them until they die and I'm forced to go 20v. I hope DeWalt will fix the adapter so it is more easily removed from the tool, I don't really want to buy adapters for all six of the tools. Ask me why I'm not a DeWalt fan.

I am confused. So which main battery do you buy to use on all the tools and then buy different adapters for each tool? And then can you use different voltages on each tool or just one voltage? And if you use a 20v. battery on a 12v. tool does it go nearly twice as fast, like when you used to put a 12v battery in a 6 v. auto?

That might work also to power up the tools that are now obsolete because they don't make the older batteries.

About 5 years ago I saw this Bosch circular saw on sale on ebay for $20. it looked like a corded saw in the picture. I bought it and when it came it was a battery operated. No battery or charger. So off I go to the store to buy a battery and charger. They don't sell them anymore because the new saws have a small flat battery. So I buy them on Amazon, $85.Battery and $65. charger, for the old style honken set.

These battery tools over the years have cost me more than the old corded ones I have had for 40 years. Always new batteries, nicon to lithium and they are coming out with a new one of a different metal.....

I think they are playing this game from the computer manufacturers, where every couple of years they come out with the new battery and then the tool is obsolete. Instead of configuring the batteries to fit the all the tools like maybe a standard configuration similar to flashlights?
That is my take on it anyway.

We became a throwaway society after the WWII and it just gets worse all the time.

not so much a throwaway society but most everything is engineered obsolescence forcing you to buy more.....
we have been thoroughly retrained..

For me it works great . Bosch is 18v battery. My black and decker are 20 v they run great. Size wise its like having old 18v nicad batteries with the adapter only works with bosch.

The DeWalt adapter only fits the Dewalt 18v tools. You then plug the 20v battery into the adapter. I don't think the tools operation is changed much by the two extra DC volts. LI batteries a really funky in many ways. I have not had great success with them. I just had to spend $400 for a LI battery for a portable oxygen concentrator. Two other batteries I inherited would not hold a charge. The supplier said they might last 2 years. Not sure we are ahead of the game with the switch to LI, and much of the rare earth used is from China.

I wouldn't take a chance on the 12v tools, and I don't think there are adapters for them.

To tell the truth, I am not fond of battery operated tools. I like the convenience of no cord,but batteries are a PITA and so is all the charging,so you have to have many batteries charged up to keep going. The weight and balance is another disadvantage on the 18v. and larger tools
But they are improved since the first ones where you had to strap a battery pack ,like an auto battery on your back and had a drill plugged into it and climb a ladder. The first ones I saw were the HVAC guys with that big old battery strapped to his back climbing a ladder installing ductwork.

I have the same adapter you do. A small file, a littte sandpaper and some dry lube and fitment problem went away.

Side note, the person who is doing the video, needs about 3 less cups of coffee before filming a video.

I read up on this a few years ago but the difference between 20 Volt and 18 Volt batteries is when the voltage is read and the allowance of government control on manufacturers. If you look in Europe you cannot find an 20V Dewalt only 18 volts, the tools and batteries are no different from the tools sold in USA. It has to do with truth in advertising, Europe will not allow hype on tool descriptions. The so called 20 volts are measured directly after removing from the charger, If you take a battery labeled 18 volts and measure it directly after removal from the charger it will also read 20 Volts. Europe requires that voltage be read after a certain amount of time at rest. The only reason there are 20 volt tools out there, was a gimmick dreamed up by Dewalt for you to buy new tools. Plus with the advent of Li-ion battery and the new cell size.The form factor of the old style of packaging with Li-ion was not up to par with old Nicad batteries in the same form factor. With Li-ion batteries in the 18650 form it is much easier to stack and lay flat. This is why all of these adapters will work, in reality all the tools are still 18 volts. We just got taken advantage again.

By the way after I read about this I decided to check it out for my self, yep the 20 Volt batteries are just 18 volts.

I could go on about this, but I figure you guys have enough about batteries and voltage.
