Electrolux ZB3104 battery replace

The customer contacted us to repair his Electrolux ZB3104 vacuum cleaner.
After consulting with the customer, we selected cells with a slightly higher capacity from the old LG HB3 (1,500 mAh) to the new Sony VTC4 (2,000 mAh).
For connections between cells we used few pcs 0.2mm pure nickel strip.
If you have some questions, you can use comments under video or you can contact us on our facebook / matejcells

Nicely done! Thanks for showing the whole process 👍🏻

Great job can you tell me what terminals on back of case is used to charge

[@chcaetano]

great. after a lot of searching I found your video. Helped me solve my vacuum cleaner problem. Thanks.

[@damiannowotka1394]

Hello. Do you need to solder the minus at the beginning, then the plugin and at the end plus? I heard that BMS is stupid if you don't do it in this order.

Onde comprar essas baterias meu amigo ?

[@csi7001]

Dear M-Cells, thanks for sharing this very useful video. please can you give me advice/help for the below questions: 1. I have an Electrolux-EER7ANIMAL vacuum cleaner with @ 37.8Wh, 18VDC Li-ion battery pack. Which type of replacement batteries is good for this device? please can you provide some exact types of high-quality batteries? 2. Is it possible to prolong the working/duty time by replacing the old, worn-out batteries, with higher capacity battery cells of the same size from renowned producer?

[@mcells_batteries]

Hi, 1. You can use for example: Samsung: 15M,15Q 20R,20S 25R,25S 30Q LG: HB3,HB2,HB6 HD2 HE2,HE4 HG2 Sony: VTC3,VTC4,VTC5,VTC5,VTC6 Sanyo: NSX,RX,SA,SAX,W,W2 2. Yes, it is possible, but we have not repaired this type of cleaner yet and we don't know if is possible replace or upgrade battery pack. You must just try it :)

sorry to be offtopic but does anybody know of a trick to log back into an instagram account? I somehow lost the account password. I love any tricks you can offer me!

@Keagan Malachi i really appreciate your reply. I found the site thru google and I'm trying it out atm. Takes quite some time so I will get back to you later with my results.

@Keagan Malachi it worked and I actually got access to my account again. Im so happy:D Thank you so much you saved my account :D

Pekná robota, len pre zaujímavosť- nebolo treba po výmene článkov zapnúť alebo restovať BMS?

[@mcells_batteries]

Vďaka. V tomto prípade je BMS kvázi jednoduchá a nepotrebuje žiadnu formu resetu. Aktivovanie BMS prebehne pri prvom nabíjaní po repase.

When I press the on button on my ERG23, it doesn't work and LED 1 keeps blinking. Can you tell me what the problem is? Thanks.

[@yuming2512]

When I press the button first, show up immediately the 3 orange lights, and then 1 red light. What is the main problem? The PCB or the vacuum motor?

[@kaczorefx]

Hi, I replaced my batteries, but now it doesn't turn on, just 1 led blinking. I checked the connections and polarity, there is a full 16V between the black and red cables on the board. Seems to be charging fine, starts from 3 led bars blinking then after a minute ends because all the batteries are fully charged already. One thing I did not do to spec is I bought bigger batteries, 3400mah instead of 2600mah - could that be the problem?

[@leonlai4096]

Hi @kaczorefx have you found any solution for the problem?? Because I've also encountered the same problem like yours.

[@kaczorefx]

@@leonlai4096 Actually after awhile it just started working - kept chargin and running :o

[@leonlai4096]

@@kaczorefx u mean even if it is mentioned( LED stop blinking when charging) fully charged? Just kept repeat the charging steps and it will start working? 👀

[@kaczorefx]

@@leonlai4096 Yeah I think. I don't really know what I did, I gave up. And after an hour or so I came back to clean everything up and the vacuum just started working :)

[@leonlai4096]

@@kaczorefx I see. Well, thanks for the information mate. Appreciate a lot of your help. 🤝🏻

[@razvanbuga447]

hey, i have a vacuum AEG CX7 , but i don't have the support for charging. Do you know which are the wires who supply the BMS , because i want to adapt a charger. thanks

[@watchmanexpert]

Where I can buy the battery ?

uz by som trhal tie rukavice od zlosti.... dobra praca.

Už som mal 100 chutí 😁 ďakujem pekne 👌🔋

[@ПавелТ-д9з]

Спасибо! А что если после замены акб, он не заряжается?

[@truthful3777]

My ergopedia is 18V therefore got 5 batteries. What are the AH of the original battery?. I intemd to replace with Panasonic battery.

[@mcells_batteries]

Hi, usually are used Sony VT that is 1100mAh. Use cells with 15A cont. discharge current and more.

[@Ryndae-l]

Would some Sony VTC6 instead of VTC4 work too ?

[@mcells_batteries]

Yes, it will be work too :-)

[@Ryndae-l]

@@mcells_batteries Nice, thanks! :)

[@slivanoubiwi]

@@mcells_batteries Hi M-Cells Batteries, are sony VTC4 not 30A continuous discharge current ?? And are Sony VTC6 a real 20A current (Some datashit says VTC6 are 30A (blog.pipeline-store.fr/wp-content/uploads/2018/03/accu-sony-vtc6-continue.png))?? It is so confusing !! Finaly wich discharge current is good to replace the old LG HB3 on this Electrolux ZB3104??

[@mcells_batteries]

Hi Slivanoubiwi , VTC4 has 30A continous discharge current with cut off when cell body reach 75°C. VTC6 has 15-18A continous discharge current. Yes we can discharge 30A and more from VTC6 but for short time, for example 30-40A for 40 seconds, 55A for less than 19 seconds etc. It's same for VTC4 example 30-40A 80 seconds, 80A less then 15 seconds, 150A less then 3 seconds . Cleaner has 10A consuption and 15A fuse. Cells with higher cont. discharge current are better. We can use every cell with 10A continous discharge current. But higher cont. discharge current of cell mean longer lifetime of cells.

You can use for example: Samsung: 15M,15Q 20R,20S 25R,25S 30Q LG: HB3,HB2,HB6 HD2 HE2,HE4 HG2 Sony: VTC3,VTC4,VTC5,VTC5,VTC6 Sanyo: NSX,RX,SA,SAX,W,W2 etc.

Boa tarde

[@satflask8330]

I must have done something wrong. The machine starts only while charging and then wont stop until not being charged anymore. Anyone have a solution for this?

[@mcells_batteries]

Hi, try check wire connections but sometimes is problem electrostatic which can damage some SMD components. That's why i use gloves.

[@truthful3777]

Looks like he used to this many times.....No need to jot where all the wiees goes through.

[@RG-hf4et]

How do you know if the batterirs need replacement or maybe the fan isn't working? Why is this so difficult ?

[@proexservis]

You dont need to replace anything in it, replace whole handheld unit for same price as for batteries (around 45€) and you get new motor and electronic board as bonus 👌 with easy replacement, just take off top cover and assemble yours. Easy as that 🙃

[@KrisBrighten]

Now the shit won't do nothing on a charger + when on a charger and I press and hold power it glows red Nothing is overheating

[@proexservis]

Red light signals motor blocked, nozzle blocked or wont charge, so it can be anything… just replace entire handheld unit and you dont need to solder anything and you get new motor and PCB as bonus (new handheld unit cost around 50€) 👌
