This is a great wood project book kzread.infoUgkxkPIWb22DigCqxmlXerCyUF4HCl6eSU2L . Most of the projects use the pallet simply as a source of reclaimed wood not as a recognizable pallet so even if you didn't have a pallet you could make these projects with any reclaimed (or even new) wood. The instructions are excellent. The style is charming and would work with lots of different decor. There are quite a number of projects that involve tiling of teh wood pieces which is a really cool idea and can produce beautiful pieces when working with aged wood.

Saved me a new battery. Straight to the point no stupid loud music. Again thanks

If you’ve never used an air filter these are great. kzread.infoUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!

My partner has a lot of tools, so when he needed a circular saw, I ordered this one for him as a Christmas gift. kzread.infoUgkxYDKeIjKLOfcwTgdin7TtCutsz4MbIc43 He is incredibly happy with the purchase. He stated that he likes that it is powerful, but still easy to use and cuts very well. He mentioned that it is important to know the right tools for the job at hand, and this compact saw has been exactly what he needed for a variety of projects at his rental properties and renovations. He also appreciates the battery packs, as stated, he owns a lot of DEWALT tools, so he is able to always keep batteries charged as needed.

THIS is how you make a KZread instructional video. Quick explanation, followed by easy to follow demonstration. No fluff, no rambling, no over explaining. Well done!

People who are secure in their abilities are willing to show anybody because they are confident in their own abilities, and have a bring it on attitude to any competition and actually appreciate others who can or are skilled as much as they are. What's sad is those who try to mislead you or tell you wrong Information on purpose to try and cause you troubles because they are so insecure about their own abilities and are worried any new fish or anybody who knows anything might come in and take their jobs. Probably lied to get their position anyways. But the real good ones can be shown the essential basics and figure out the rest with relative ease especially if they pay attention to what an old schooler does. Most old school people are more than willing to show thirsty younger people who want to learn, only problem is most young people these days don't care enough to thirst and are lazy to boot, plus they are know it alls.

When disconnecting batteries, never pull both leads out of one battery first. No matter how careful you think you are, sooner or later you'll let those two wires touch and short out the battery that the wires are still connected to. You always disconnect one lead first from each of the two batteries and then disconnect the second lead.

Warning. Only do this in an emergency. If you manage to charge this battery, do not keep this battery anywhere it can cause a major fire. Why ? When these batteries are discharged below 3v per cell, dendrites (small spiky structures) can grow and possibly pierce the separator between the anode and cathode of the battery, causing a short circuit, and thus a fire. Most consumer electronics will regard 3.3v as fullt discharged, and the battery protection circuit will then turn the equipment off to prevent over discharging. If a cell is found to be 2.3v or lower for anything by the a very brief time, then it is effectively dead, dendrites will have certainly grown, and even if you manage to charge it, the dendrites are still there, and you now have a ticking time bomb. Do not reuse such a cell. Once that separator is pierced you may have a fire, the intensity of that fire will depend on how much charge is stored in that cell. If your battery pack has been dischared for some time, open it up, and measure the voltages directly accros the individual cells. If this is less than 3v, do not attempt to charge. Even if there is not a fire, you will notice that after charging, that cell will self discharge within an hr or so. This is due to a partial internal short circuit caused by dendrites. More energy put in to such a cell increases the risk of fire. You have been warned.

What I have found in the lithium batteries I've played with, have a computer chip inside to control charge rate, heating, etc. When the battery is completely dead, there is no power to run the chip. I have directly charged cells with a 9 volt battery, current limited, to get enough charge to run the chip, then the battery will charge normally. So what is shown here is correct, with a slightly different background.

If a cell is found to be 2.3v or lower for anything by the a very brief time, then it is effectively dead, dendrites will have certainly grown, and even if you manage to charge it, the dendrites are still there, and you now have a ticking time bomb. Do not reuse such a cell. Once that separator is pierced you may have a fire, the intensity of that fire will depend on how much charge is stored in that cell. If your battery pack has been dischared for some time, open it up, and measure the voltages directly accros the individual cells. If this is less than 3v, do not attempt to charge. Even if there is not a fire, you will notice that after charging, that cell will self discharge within an hr or so. This is due to a partial internal short circuit caused by dendrites. More energy put in to such a cell increases the risk of fire. You have been warned.

Thank you sir you have just saved me a bundle of money , as some others had batteries sat dead for a few years , got board tonight and thought you tube ,,, amazed to see the dead battery finally charging , next is 54v will try that ,,, you are totally right , funny thing is the worst thing for a dewalt battery is the piggin dewalt radio ,,, thumbs up mate

Thanks, Mattew this video got me going again in 5 minutes and most of that time was finding wire and stripping the ends.

Well Mathew, I can't tell you how helpful this has been. I have already taken 4 different batteries back to Dewalt to have them replaced just for this very reason. Many thanks for some extremely helpful info sir and you now have a new subscriber!

Thank you...that worked for a 20V Max Li-on!! 👍 I used four box cutter blades inserted into the +/- terminals on each battery - one fully charged, one dead. Then connected those in polarity with two jumper wires that had alligator clips on each end. You're spot on: "only for a few seconds." The jumper wires were getting warm after 10-15 seconds. The dead battery started charging when placed on the charger. The dead battery had been left in a tool for a few days and died. Not worried about "old" battery revival issues with it.

Look! He even buys official black and yellow DeWalt brand wires! :D (Great vid! No wasted time or annoying music or BS. Thank you, sir!)

under no circumstances do this without testing cell voltage first (open the battery up and check the voltage acreoss cells), YES it can work if the cell voltage is still above 1.9v , if it has dropped below 1.9v and you do this you run a high risk of overheating the cells as the cells can experience dentritic growth between cell layers and cause short circuits

@SaltyBrainsif it's been entirely depleted then it is no longer a good cell, it is best practice to dispose of them

The only risk is a totally discharged battery changes chemically and can become internally shorted. Be very careful when charging and using it afterwards as it could easily catch fire.

I am shocked that I had to scroll so far in the comments to find a warning about the fire hazard in doing this.

Just tried this on a pair of 12v 5Ah DeWalt batteries and it worked perfectly.

Top video. I haven't tried this technique yet but will in the morning and let you know the results. What impressed me the most was your concise, straight to the point delivery. No long intro and many minutes of my existence lost to unnecessary waffling. 😊

This worked ! I was skeptical, but I was so happy ! So simple. Thanks !

Yes this does work, my 20v battery pack read 2.0v, i bumped it with another 20v pack for a 2 sec and it gave it a surface charge of 12v decreasing to 7v which is enough for the charger to recognize the battery. This can probably be done using a 9v battery as well if you only have one tool battery since your only giving it a small surface charge

If the cells have briefly (a few hrs only) dropped below 3.3v, but, not below 2.3v per cell, then ok, have a crack at charging, but, there is increased risk of fire. 3v can be revived ok providing the cell has not been sitting @ 3v for period of time. More time below 3v = greater risk the anode to cathode separator will be pierced from growing dendrites, causing a short circuit, and hence a potential fire hazard. You have been warned.

Seen it done but had no faith. Worked like a charm. Short and sweet video also, straight to the point. Much thanks to you good sir!!

Warning! There is a fire hazard if you do this! There is a reason why the charger will refuse to recharge a dead lithium ion battery. It may get internal chemical damage leading to a short and thermal runaway. In an emergency it can be done (I used a resistor to somewhat make it safer) but the battery shall regarded as unsafe for ever after that. I must be discard in some safe way.
