Battery conversion of Black & Decker Cordless Screwdriver

[@duncancremin1708]

Excellent video. I have an even older version of that and it was certainly NOT cheap when I bought it. It came with a combined wall mounted holder and charger. Tge build quality is so good that even after the batteries died, I kept it and I still use it when I want the extra torque I can apply due to the large, comfortable handle. I did replace the original batteries in it once, but the replacements didn’t last nearly as long as the original ones and I started using a cordless drill instead, when those died. I hadn’t thought of changing the batteries for modern ones, until I saw this. I must do that. I have converted old drills to lithium, so no idea why this never occurred to me.

[@DaftOldMan]

Thankyou. The quality of these early tools is much higher than newer Black & Decker tools for sure.

Perdón...buenas tardes, hace un tiempo yo hice lo mismo que usted, pero a la salida de la pila 18650 hacia el motor, en su terminal positivo (+) le puse en serie dos (2) diodos rectificadoras de 2 amperios cada uno, los cuales hacen caer 0,7 Volt cada uno aproximadamente, logrando bajar de 4,2 volt que es cuando esta cargada la celda 18650 a 3V. Es lo más parecido a la realidad original. Saludos y excelente video! 😉👍

[@DaftOldMan]

No necesitas los diodos para bajar el voltaje. Al motor no le importa un ligero aumento de voltaje.

[@ciscoworld_XD]

pienso como ud, pero hay varios fallos #1 ese modulo antiguo no tiene protección de la batería como lo tienen las versiones mas modernas que tienen adicional la salida positiva y negativa independiente de la entrada de carga, y en vez de colocarle 2 diodos le colocaría otro modulo un step down y así le bajaría el voltaje exacto y preciso al original , además cambiar la fuente de alimentación ya que esa fuente es de muy bajo mah ese modulo trabaja con 1a , y con la respuesta que el da sobre el motor , hay que verificar bien cuanto voltaje dc como máximo soporta el motor, pero si lo que yo quiero es dejarlo como el original lo hago con los 2 módulos el tp 4056 con protección de batería y el modulo step down para dejarlo como el original y usando una fuente de alimentación de 5v 1a

Thanks for your video, I have the same screwdriver B&D 9018 2.4 V since about 20 years. I didn't use it for 12 years and when I was to use it again the battery failed, I bought some others that didn't work. Thanks to you now, I know how to fix it.

[@DaftOldMan]

I am glad the video helped

[@andreika6681]

i've bought the same 9018 on flea market for 2 euros, without charger, fella thought it was useless, and from another fella i've got a broken vape for 1 euro. vape had 3.7 good li-mh battery inside, and i had nine eagles li-ion usb 5v->3.7v charger dongle, so, it all vent inside 9018 and it works great now ! 3€ invested and 30 mins of my time, but it was fun to get that thing do to its buzz again and i charge it now on usb male-femaile extension cable

[@tamaselek353]

I’ve found one in the “trash”. It’s B&D KC9024 similar to this. Someone has converted it to wire only mode. I tried it and works well, so after your video I was inspired to make this work again without a cable. I have now the battery and the charging circuit so all I have to do is make it done. Great video. Thanks.

[@DaftOldMan]

Hey. That's good news. Another old tool saved and they work real well with liIo battery power.

[@tamaselek353]

I like when a tool is saved from the death if it’s still usable. I'll do the conversion on weekend.

[@elemperador2]

It worked perfectly for me, it is connected as you told me. When it is connected right, does the module turn on a light when the battery is low or does the module automatically cut it off?

[@DaftOldMan]

When you connect through the module the module will cut power at 2.5v. The modules work fine for bulbs and LED's but motors can cause the module to cut power every time high current is pulled. I just charge mine when ever the motor feels slower. 2 years of use now and the battery is still ok.

[@elemperador2]

@@DaftOldMan Perfectly.Thanks!.

[@maneproen]

Why do you need the control circuit for the lithium battery?

[@DaftOldMan]

Lithium battery must have charge control to stop charge at 4.2V. Without charge control a lithium battery can catch fire.

[@nawafaladwani6164]

Great Job but instead of cutting the black wire on the charging input side you should have removed the old one and connect the new one in it place, less joint to wary about. thank you for a great presentation

[@DaftOldMan]

I agree, but it works well so It should be ok.

[@AxellTh]

Will the 3.7v battery not damage the motor made for 2.4v?

[@DaftOldMan]

No. Motors are rarely made for one exact voltage so 3.7v just gives a faster speed so it may wear out quicker.

[@TechTokOffical]

These are actually REALLY well made and ONLY downfall was the batteries

[@DaftOldMan]

I wouldn't say they are well made but I use my repaired one almost daily and hardly ever need to charge it now so it is pretty good.

[@charles_cachia]

i did the same but please note the bms u are using is max rated at 1amp...the tool goes up to three when under load so it wont last 😞

I do not use the bms for output, only for charging. 4 years later it still works perfectly.

[@DaftOldMan]

@@aaaronmiller100 Yes the diode seems to be to stop the old batteries going flat if you left the screwdriver plugged into the charger with the charger turned off. This does not apply with the LiIo battery and infact the LiIo charger will not function correctly with the diode left in circuit.

The LED's are part of the charge control board.

[@battsy2911]

Isn't 4.2v too much for a motor rated 2.4v?

[@DaftOldMan]

No. DC motors are not rated at one specific voltage. My dremel that I converted to a 12v motor runs on 30v DC with no problem at all. At higher voltage the motor may spin faster and wear out sooner.

[@cezarfr4506]

I´ve got a doubt, , how many volts and amperes the charger works?

[@DaftOldMan]

5 volts, 2 amps

[@fourbrothersfarmsfarm99]

What kind of charger can you use for it?

[@DaftOldMan]

Any 5V charger. An old mobile phone charger will work.

[@fourbrothersfarmsfarm99]

Thanks old man

[@robertbanfield7164]

Shouldn´t the charger be a 3.6V? Why 5 Volts?

[@DaftOldMan]

The charge control board requires 5v input. The maximum output is 4.2v for a fully charged battery.

[@LondonLocksmiths]

Interesting how the chargers for these old drivers are AC rather than DC

[@DaftOldMan]

Thanks for commenting. The charger is AC but the screwdriver has a diode to give terrible rectification to DC. I assume NiCd batteries were happy with this.

[@LondonLocksmiths]

@@DaftOldMan lol, why use one diode when 4 would do the job properly. I was a Black & Decker service centre manager back in the early 90's, these drivers and the dust busters were the bane of our lives.

[@joemoncrief4104]

What is the polarity of the plug in for the charger? Is the center pin negative or positive?

[@DaftOldMan]

center pin is positive but it doesn't matter as I use a diy charger

[@fvfgx]

You don't need to do all this chip soldering, Just need to use a DC to DC Buck converter and set the out put to 4.2 volt and it will stop charging due to it reaching an equilibrium

[@DaftOldMan]

I have a torch here that has a dc to dc buck convertor but it still uses a battery charge/ discharge protection board (BMS) so I guess the manufacturer does not think a buck converter on its own is good enough.

[@Kastoraki]

Hi, i have a question, how much current allows the TP4056 to let through before cuts out? I have a similar screwdriver B&D and i have the same idea but technical characteristics of a TP4056 writes that cuts-out at 3A and above. I measured the current of the motor in heavy load and is at least 6A with 4V....If you can pls answer to a fellow DIY...
