Join me in this step-by-step tutorial as I demonstrate how to replace and upgrade the battery in a cordless screwdriver. I'm swapping out the original 600mAh industrial batteries with high-capacity 2500mAh rechargeable ones, significantly boosting the tool's performance and runtime.
Please Note: I am not a professional technician, and this video is for informational purposes only. If you choose to attempt this battery replacement and upgrade, you do so at your own risk. Incorrectly connecting batteries can result in hazardous situations, including the risk of explosion. If you're uncertain about the process or lack experience with electronics, it's advisable to seek professional assistance.

I'm a bit surprised that you didn't use/need any solder flux paste! Nice work. Thank you for showing us !
Thanks for this, Kat . I just finished my battery replacement. Not where near as clean as yours but it's working.
So helpful, so professional! Thanks.
Exactly what i was looking for. Thank's for sharing.
i agree.. freaking perfect
Thank you so much
Very nice job. Thank you. Does the heat from the soldering gun degrade the rechargeable battery?
If only you'd had a cordless screwdriver to undo those screws
Lol, if life was that simple :D love the username ;)
lol
Nice. Exact same screw driver with mine. Thanks for the tip. Keep up the good work... :D
I'm glad you like it. I'm not an expert but it doesn't seem to affect the battery. If you file the ends of the battery enough, you won't need a lot of heat ;-)
I'm assuming the batteries that were in the driver were NiCd while the ones you put in are NiMH; is there an issue using the same charger with the different chemistry (in particular because it's probably not a smart charger)? Electro-wizardry is not my specialty.
Lol, like you called it Electro-wizardry is not really my speciality either :) I believe the old batteries were NiCad and replacements were NiMH and the charger is most definitely not a smart charger. All I can tell you is that there doesn't seem to be any charging issue. As normal the charger and the batteries do become a little warm during the charging process, but as far as I can tell not warmer than they did before their replacement ;)
Thanks; I found this video looking for reviews of the more-or-less throwaway driver that I'd like to have for odd jobs that don't warrant a drill or impact driver (or that would be unwieldy in that application). I would be very likely to try this mod should it be the batteries that go kaput (instead of, say, the motor/brushes/switches). Thanks for the video.
Thanks , great help! I couldn’t get my brand apart, there’s a screw underneath the sticker😉.
Hello there would you please advise me where the red wire from the battery is connected to
The rubber band for the initial battery arrangement was a nice touch! Thanks for sharing!
Thank you ;)
nice video I have the same screwdriver (green) I'm going to do the same
I have the same model, green. Just replaced the batteries (4.8v 1800 mAh) same as you did (just very much less professionally). Then, I had smoke coming out of the screwdriver while charging. Any idea what may have gone wrong?
Excellent video. Did you need to replace your charger when increased amperage of your batteries?
Thank you ;) I didn't need to replace the charger but when I charged the screwdriver for the first time I made sure it was not getting hot ;)
hi.. i just browsing and found your video... excellent if i might say as it is informative, short, compact and easy to understand...
few questions that i have already got the answers from the comments, but i have a question that would very much appreciated if you know the answer or opinions on 'how to' the problem..
i lost the charger for my cordless screwdriver and the specs is much the same... 4.8V, 600mAH - how or what charger can i use to charge the stock unit? I tried using a modem charger which gives an output of 5V, 1.2A but even i left it for 5 hours it is still weak. Hope you can respond to this.. thanks
Thank you, the charger that came with my screwdriver is 6V, so if you do have one I would give that a go ;)
Easy to follow and love the music, what's the name of it by the way?
Thank you ;) the song is called Pink Lemonade by Silent Partner and you can download it here if you like th-cam.com/users/audiolibrarymusic
Just asking: you replaced with another NiCd batterries, am i wrong?
Can i improve the voltage instead of 4.8?
hi, i
How long can/should you charge?
what were the noticed improvements in performance?
It's definitely more powerful than before. The main reason for me changing the batteries was, that they would no longer hold the charge (lasting about 2 minutes), hence the screwdriver was pretty much useless. It feels like new now ;)
Please help me find where to replace batteries in my cordless screwdriver
i have an older model of this same screwdirver and im trying to replace the batteries but cant get it open. ive unscrewed everything and have been able to seperate it a bit but theres one section that just wont budge and let me open it. im not sure what to do without breaking it
any advice?
There's another screw under the sticker. You'll need two sizes of star bits since the one under the sticker and the chuck assembly use smaller.
how to refill? default charger?
great video Thanks! The small metal tabs you soldered on were cut from ?? or are they a hobby store item? thanks for your help.
I think it was just a piece of scrap metal, but you could also use a piece of wire, shouldn't make any difference ;)
@@nerdyKat what kind of metal?
Can I replace it with orginal ni-cd with ni-mh with same charger?
I don't see a problem with that ;)
i did the same when my screwdriver's batteried died after a few years. I put in Nimh batteries for higher capacity instead of NiCd batteries like originally inside. It certainly last longer now however there is a catch. Nimh batteries have higher inner resistance, so they can't give that strong torque as NiCd batteries. but anyway..
If you are replacing a 600 mah with a 2500 mah, is there not a risk of overcharge, overheat and danage the circuit? I have a 12v one, 3.7 v each with 1500 mah each battery and am worried to replace with a 2000 mah each. If It has not a protective circuit may damage the screwdriver ?
Your question leads me to think that your not sure what mah means that's ok I'll try my best to answer for you. The incoming and outgoing power won't change just because you're adding more mah. Take for example AA batteries, there are all kinds of different brands and many mah ratings, however, they are all 1.5 volts. There is no chance of overcharging if you're adding a higher mah battery. A higher mah number only means that the battery can store more energy, means it has a higher capacity. For instance, a 3000 mAh battery could power a device drawing 100 mA (milliamp) for 30 hours. You could even put a 1500 mah battery into a device and it would run a 100 mah device for 15 hours. I Am not sure how undercharging or overcharging works so I can't answer that part of your question. The simplest point is that the output voltage doesn't change with the raising or lowering the capacity(mah) of a battery.
@@KoolBreeze420 well I am a financial not eletrician but I know amperes and microah as units of measurement only .thanks for your help!
@@jfrncjr Sorry if you think I said something demeaning that wasn't my intention.
@@KoolBreeze420 No need to be. YOU were VERY HELPFUL and explained Very well! Thanks a Lot!
@@KoolBreeze420 Hi koolbreeze! I am studying this issue to change mine. And found another problem that you may kindly confirm . An upgrade of Mah will make the original charger take longer to load the battery. It seems that each 1000 mah with one 1000 mah output charger, takes one hour to load the battery. So If I double the battery , It Will take TWICE the time to load
:(
I presume the original charger can still be used, then? Nice job!
Thank you and yes it certainly can ;)
I have to fix same issue . thanks
thanks chick .
You're welcome ;)
Instead of using 4 AA Batterys
Use 2 18650 batterys & use a peice of tin to
Connect them in seiries then glue in 2
Peiced of tin & solder the red wire
For + & black Wire for -
Wouldn't there be a difference in the volt. 4 AA will have a volt of 1 .2 X 4 = 4.8 . 2 18650 will be 7.4V as each is 3.7V.
1 question stock voltage is 4.8 will circuit hold on to 4 x 1.5= 6V ????
I don't think that would be a problem, however most of the rechargeable batteries I've seen were 1.2 V which would give you the 4.8 V ;)
SIMPLY FAB INSTRUCTIONS. NO DRAMA JUST STRAIGHT FORWARD ANSWER VIA VIDEO TO MY QUESTION.
I AM IMMEDIATELY SUBSCRIBING TO NERDY. 😘JUST LOVE NERDY.
Hi..nerdy kait ...I'm interested in your chanel
It battery size in v
You should use a spot welder instead of soldering the batteries together because you could damage them
Her technique keeps the heat exposure to about a second each time. No prob.
Will you marry me?😂❤️
Lol, thank you very much for your lovely offer, however my heart already belongs to another ;)
@@nerdyKat Lucky (if) Techy
Mine broke first day this is bullsht
al mio no se le apaga la luz roja aunque este veinte años cargando
You didn't do it correctly.
