PARKSIDE 20V lithium battery repair

[@ErCanEverything]

Good battery repair video, well done👏🙂🤝🤝🤝

[@RefurbishmentKJ]

THANKS😆

You need to use cells with similar resistance and capacity. 25-R are 2500mAh, old cells are 2000mAh (New). There will be problem with balancing. You should use Samsung 20R or something similar as replacement.

[@RefurbishmentKJ]

Thanks for reminding

[@davey2k12]

I've recharged a few that 1 cell went too low and wouldn't charge and don't look like the BMS balances nothing just a protective circuit less there's a new version .... Put what ever cells you want in there cus the 2ah ones am pants anyway

[@MrGodsking]

@@RefurbishmentKJ can you upgrade mine if I post to you they are all new but faulty

[@orlatris96]

Excellent, I loved your work. Highly didactic, perfect.
Thank you so much for sharing this simple work.
If possible, could you tell me what liquid you used to clean the plastic parts?
A hug

[@RefurbishmentKJ]

We use car engine compartment cleaner, which is called nose water here. I don't know what to call it in English.
Good degreasing and decontamination effect.

[@mcirelandosharma7411]

Carb cleaner would be an automotive name for it 👍

[@silverxiree]

@@mcirelandosharma7411 no it is not the same thing. carb cleaner would ruin the plastic parts. this solution is called in English exactly engine bay cleaner or engine compartment cleaner.

Great video! Just a question: How did you weld the contacts to the liIon cells. Which tool do you use for it?

[@RefurbishmentKJ]

Thank you！It is welded with a spot welder.

[@Bianchi77]

Creative video, thanks for sharing :)

[@wizzardrincewind9458]

good work!

[@RefurbishmentKJ]

Thanks!

[@MrNickadu]

Excellent work ... well done !!!
I wanted to ask you, what SPOT WELDER did you use to make the electrical connection to the batteries?

[@RefurbishmentKJ]

The spot welding machine is made by myself and is controlled by super capacitor and mos tube.

[@MrNickadu]

@@RefurbishmentKJ Thank you for your answer.
Do you have a video of your construction of spot welding machine ?

[@ghostalpha6873]

hello, good job you did there. but I'm not sure it's a good idea to replace only 2 cells with different cells, it could cause problems in the future. that said, it's a nice repair

[@RefurbishmentKJ]

Thanks, that's not right, but I don't have any other batteries.

[@nothingbutthetruth7900]

Is it not better to just replace with same amp hours cells so theres no balance problems?

[@RefurbishmentKJ]

I don't have a battery with the right capacity.😅

[@greennich777]

Good job 🥰😍🤩🥰😍🤩

[@RefurbishmentKJ]

thank you

Hi, it I have received 2Ah battery, manufacture in 2018. It volts are ok but it was not charging (red and green blink) then it drill only works for 1 second and shuts down until next push of button . I measured all cells was perfect balance. I then removed pcb and on other side found one track damaged it was a cell connection to balance circuit, after solder back it then started to charge but after 5 minute of charge it then again green and red led blinking and still same it after one second it drill shuts down. what can be wrong....

[@RefurbishmentKJ]

Some boards are protected and have a short circuit before that can cause the PCB to lock up.
This fault seems to be a bigger problem with the pcb.

[@ZangerMarvin19]

Wat machine you use to connect the connection plate back to the battery cell? Looks like point welding but i need to know wat is the name of it machine

[@RefurbishmentKJ]

It's a spot welder

[@MacStrange]

Really good

[@RefurbishmentKJ]

thank you

[@ComputerTechNL]

Use the orginal nickel strip that you use is why too thin

[@florinmunteanu1670]

Metti link con tutti prodotti che h ai utilizzato per riparare questa batteria....sarebbe comodo per noi ...così compriamo pure noi tutti materiali .....così cerchiamo di riparare pure noi una batteria....grazie

[@oudlakhdar]

thank you

[@achimgazelle3641]

Is it also possible to fit 5x Panasonic NCR18650B 18650 3400mA? That would theoretically be 17A strong or am I wrong?

[@XSAILOR65]

Wrong. 5 will give You 3,4 A, with 10 (5s2p) of those You will have 6,8 A. NCR18650B has too bad max discharge current, not working in this application.

[@valdaskdn]

doesn't lock the bms chip?

[@RefurbishmentKJ]

This battery will not lock the chip

[@mandamados]

never use batteries with different capacity, they charge and discharge with different rate

[@RefurbishmentKJ]

Thanks for the reminder, I will pay attention to the battery next time.

[@nelchan2421]

please don't add cells with higher capacity
