How to take apart a 20v DeWalt Battery

The title says it all. Basically just confirming that the cells are just "friction fit" and require a safety torx size 10 bit to remove the screws to open the casing. If it's an old battery then it will be more difficult to remove than a new battery.

I was able to take the innards of a 5ah battery that had a damaged case and put it into an old 4ah case. Fit perfectly, just wrote "5" on the side so I would know what it was. Maybe someone else could confirm that 3ah batteries (I don't have any 3s) have the same dimensions inside as well.

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

My brother just brought me pack and it's full of 20s 18650 calls super excited

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

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

Good demo. Actually Lithium does not explode, it's the electrolyte that explodes. Good demo though.

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...

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.

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?

Do you think there could be counterfeit batteries out there?

[Ferguson.]

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.

Are the cells 18650 li/ion? Also what company is written on them?

[marsupialsrock]

You can use a tiny flathead screwdriver to take out the safety screws without breaking the little pin in the middle

[johnsmith-skep]

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.

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?...

[rennestrubberg]

So does the 5ah guts fit in the 4ah case any help would be greatly appreciated

[moisestheentrepreneur]

These look like samsung 25R 18650 batteries.

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!

It is called a tamper resistant screw.
