You're the bomb buddy watching your video gave me the balls to open up my 2-week-old 20 volt 5 amp that fell off the top of a 9019 foot skylift and popped the casing out of alignment wouldn't fit back in the tool now fixed save me a hundred bucks, I'll be sending you a Christmas card
I wish the video showed the actual cells at some point. I assume they are 18650 cells. I watched the video just to try and find the type of cells that are used by the actual DeWalt batteries.
Thanks for posting. I was wondering what kind of screwdriver to use. I took a 3/32 drill bit and drilled the pins off the screw head and took a regular Torx - 10 screwdriver and got the screws out
You can't be 100% sure, but when I have tried to purposely damage lithium ion it has taken a lot of force and actually piercing through it for it to be damaged. However, we all know they can burst into flames, even without damage, so you'll have to decide...
Appreciate the post even though I’m late to the party. It has become nearly impossible to purchase from some authorized retailers without “accodentally” ending up with a few counterfeits that sneak there way in. I believe instead of lime green Samsung cells there are yellow? Pink? So much stock is swapped and stolen from Amazon and Home Depot. I think it’s weird that I have to actually have to check the guts of a tool nowadays just for peace of mind. ‘’merika
So I'd say that it's pretty easy to tell a fake in the battery world once you take it apart. The innards of a fake are generally pretty poor. The contacts are loose and the battery contacts are small. There are a couple of good videos online and DeWalt has released some info on fakes as well (just by looking at the housing there are some tell-tale signs). I wouldn't focus on the cells because manufacturers do use different cells as supply changes.
The fusible link on two of my DCB205 20V 5AH Dewalt batteries has melted. I can't seem to find a place to get a replacement. Can I just Solder bypass it? What do you think? Comments?
If it melted it would make me question the integrity of the cells themselves if it got that hot, but if you are able to confirm their integrity (no expansion/bulging/deformity/staining), then I would watch some videos on guys putting together 18650 cells and what gauge of wire they are using because using a certain gauge of wire can act like a fusible link in that it will melt at a certain amperage draw. I don't know where you live but somewhere has to have some fusible links for sale, or sacrifice one battery as a "parts battery" and use the links off of it. I wouldn't just solder on any old connection as you don't want your battery exploding or catching on fire. Good luck!
Yeah, definitely. However, there probably aren't too many because the labor required to swap out cells is fairly intensive and most knock off batteries that are made are easy to identify as such.
@@MyFortressConstruction I purchased an 8AH on Amazon but it arrived in a small cardboard box with no paperwork or anything; I found it odd. I compared it to some of my DeWalt batteries and found some alarming things wrong with it, so I returned it. The battery indicator was different and the torx screws were not the security type. I think dewalt might have thrown away some of their worn production tooling and someone in China got their hands on it.
I appreciate the effort, but you just glossed right over the most critical part. Just how did you get the T10 screws out? Did you have the "safety" Torx driver? Did you break out the pin? If so, how?...
@@MyFortressConstruction okay thank you - planning on making my own out of recycled laptop batteries and have a few im fixing anyways. Here in canada the 2aH pancakes are any where from 60-90 dollars. 2aH is a fart in the wind for getting stuff done
@@pjosephsmith Yes, 2ah is fine for homeowner tasks, or when you want something lightweight, but I have about 16 DeWalt batteries ranging from 5-9ah. Are you going to wire the cells together and place them in old casings?
Wiring them in series will change the voltage, and then you can wire them in parallel to get the amperage. This would be if you were modifying the batteries for use in something outside of a power tool. Though, technically speaking, you could take (3) 5ah 20 volt batteries, hook them up in series so they become 60v (54v in use), and you would have a 5ah 60v battery to run a flexvolt tool off of. Or you could hook them up in parallel to get a 15 amp hour 20 volt battery.
Didn't work for me. Discovered today I might have bought fake batteries on amz so I wanted to look at the cells but can't get the top off without destroying the battery. Got it part way off but couldn't see the cells or what exactly was holding it together and then pia putting the cover back on without destroying it too. Dewalt has this document on how to spot fakes but when I looked at the product battery on hd, according to dewalt it's a fake. I guess I'll have to wait until it fails now to find out if it's a fake or not.
The battery he is showing u is also fake. Because dewalt batteries do not come with safety screws. I have numerous dewalt batteries. None have safety screws
Yes, I got 5ah XR cells and fit it into a standard 4ah case. Have to be careful as there are compact batteries and even flat packs now. But the OG 4ah and 5ah are interchangeable.
Lol. Same thing I think when I play some of these back! There is definitely a skill to teaching and making videos. A lot of times you just find yourself thinking too much while you're talking and it means you aren't focused on presentation. I am hoping to get a little studio set up in a couple of months so that I can focus on information and presentation more. FYI, you're not a hassle, and I enjoy this a lot! 😆

Lol, glad it helped.
My brother just brought me pack and it's full of 20s 18650 calls super excited
Needed the battery model number; got it thanks to you, thank you sir.
Lithium doesn’t explode, it catches fire, lipo’s explode.. but thanks for the video, nice job, appreciate knowing what to do.
Thanks for the video! I have several 18640 samsung that I had from a proyect and I wanted to replace a cheap battery pack with those
I wish the video showed the actual cells at some point. I assume they are 18650 cells. I watched the video just to try and find the type of cells that are used by the actual DeWalt batteries.
I'm fairly certain this battery had Samsung cells. They are definitely 18650s but I think I've seen red LG cells in a DeWalt battery before too.
Good demo. Actually Lithium does not explode, it's the electrolyte that explodes. Good demo though.
From my research, lithium metal is explosive and so are some lithium salts. Do you want to elaborate? I'm certainly not an expert.
Thanks for posting. I was wondering what kind of screwdriver to use. I took a 3/32 drill bit and drilled the pins off the screw head and took a regular Torx - 10 screwdriver and got the screws out
Risky, but it works!
I got one 18650 scratched to the metal and gently bent 0,5mm inside from the screwdriver. I wonder if this will be a problem...

Do you think there could be counterfeit batteries out there?

You can use a tiny flathead screwdriver to take out the safety screws without breaking the little pin in the middle
I appreciate the effort, but you just glossed right over the most critical part. Just how did you get the T10 screws out? Did you have the "safety" Torx driver? Did you break out the pin? If so, how?...
just buy the correct screwdriver, there is Chinese kits everywhere for less than 10 dollars and you will have correct screwdrivers for everything
What's the torx screw size?
I offhandedly mentioned the size at 0:42. It is a T-10 bit and you will find that a lot of manufacturers use that size.
These look like samsung 25R 18650 batteries.
Are the cells 18650 li/ion? Also what company is written on them?
Yes, 18650s, but I don't know what the company was.

So does the 5ah guts fit in the 4ah case any help would be greatly appreciated
Yes, I got 5ah XR cells and fit it into a standard 4ah case. Have to be careful as there are compact batteries and even flat packs now. But the OG 4ah and 5ah are interchangeable.
It is called a tamper resistant screw.
I think they're mainly referred to as security torx screws. I think you would find it if you typed in security Torx size 10 bit or screwdriver.
You might want to wait until you’re not bored out of your mind before creating a video. You sound like we’re just a hassle to you!
