Can you please post the link to the video for the older style batteries . Thanks

That was 0.1 mm or 0.15 mm nickel strip?

See my CX500 exhaust video also!

What did the cardboard pieces insulating cards do? Do I need to install them?

very good video

Nickel strip size please

Thanks for the vid. Learned a few new techniques

Nice video mate! Was quite surprised when I realized that's actually my battery, thought I'd give it a go myself this time!

Greetings. can I send you my battery for repair?

Superb.

Awesome video. I have question about 18650 battery brands. Does it have to be exact brand and model or just 18650 with same specs? What you recommend?

What would happen if you kept the spot welder set to 45 for the main strip (from circuit board)? You mentioned you dropped it down to 20. Would it just create a deeper spot weld if you kept the setting at 45?

Does anyone know what size batteries are in the 12 ah packs?

Throw some 25s in there and get a big upgrade both in A out and capacity. Imagine they would play ok with the onboard BMS. Cheers.

Wow. That sounds like a badly tuned tractor. Yuck.

Awesome video. You made it look easy.

Hello I enjoyed watching your video! Did the same half a year ago. Both packs will not load full. Wenn i testet the cells. I found out that the charging process is only charging the first cells in series to 4.2 V the 4 cells behind are not charging. And staying at 3.7 V. Anybody any idea?

Real nice work!

Hey were can I buy the battery for m18 battery please can u send me a link or anything that will help me find battery cells for m18 5.0

not worth repairing unless you have extra batteries laying around. the cost of putting all new cells is not worth it.

Subbed to ya for this vid. Ive got a couple these. Whether they old or new they look a lil different. Im gonna try to repair them, thanks for the good vid on em.

How did you know that was nickle pladed copper it look just like the nickle strip wire to me

sir my Bosch 18 volt battery indicator not working 5ah lithium ion battery

Hey, good video, dod you end up uploading the video for the older style fof battery? Couldnt find it on your channel list

Thanks, with your video I fixed a bad connection in my BAT620.

I enjoyed your detailed step-by-step video. Thanks mate.

I have an identical one that flashes an LED on it and does not charge. The batteries are good. What is the problem?

Great video, only thing, you were making adjustments to the welder, realize this was for different number of layers, would be helpful if you gave the settings, not all welders perform the same but it would give a tip to the percentage increase/decrease required.

Awesome video, thanks.

Hi, what thickness of nickel strip did you use?

could you post links to websites for the tools and supplies?

How do you reset a BMS board into life after it locks up, and shows a fault on the battery charger.

What is the name of that spot welder and where do you get one?

I'll just buy a battery thank u

Can you show any lights on why my battery do not make contact with the drill battery connection, when pushed into place ?

I don't have a charger but I've changed the cells of my milwaukee battery and the lights don't turn on😂😂 Luckily to find this video

Is that the original exhaust or an aftermarket one?

What type of spot welder your using

Fun fact Walmart sells those 18 650 batteries for their solar lights and at the end of the season they're often on clearance and I got a pack of four for $5.

Excellent adaptation! Now I need to get my own set up. Actually, for an aging friend in need of a new income path here on Nampa Idaho. Thanks for the excellent video on the complete replacement of batteries / packs! Jim Scott

After watching your repair, I braved doing mine. My battery is a newer M18 5.0 encased in plastic and each cell pair needed to be pushed out of the plastic housing. 8 of the 10 LG cells decided to go dead 0v. One pair was still going strong. I tried to kick start dead cells but it wouldn't hold a charge. Thankfully I had kept the cells from a broken (plastics) Hoover cordless vacuum which used Samsung cells. Battery was in great condition and I kept the cells charged with an 18650 charger. I swapped the cells in and bam its back to life. I needed to plug it into a charger to wake up the electronics. I don't have a spot welder, I only have a resistance soldering iron, I just soldered the tabs in. With a resistance soldering it heats up the joint quickly and then with my foot switch take the heat off and cool it down quickly. Not ideal but it works. I'll keep it around for light duty work. Fan, portable vacuum, etc.

Is the spot welder anything special or did you just get a generic one off of Ebay?

Did you get the spot welder in NZ?

GREAT! Question: Since you have opened the battery don`t u think it would be a good idea to clean the Circut Board.. I ask it because, as it looks, they accumulate a lot of dirt and dust that could affect them.

Worked great! Batteries last for Days now. Only thing I would watch out for is that your careful when removing batteries. I was able to use pliers to either cut the welds or pull the nickel plating apart. I used a spot welder off of Amazon and Eve batteries from the 18650 battery store.

Fantastic job. Well done

Very nice 👌🏻

If you made this video for learning purpose that's ok, but in the real life buying 10 brand cells (plus accessories) will cost near the same or even more than what you would spend by buying a new Bosch battery. And now Bosch make the Pro Core one which uses the latest Samsung 21700 cells which make the pack smaller.

Hello. Is it possible to replace original cells, for example 1500mah 20a, with 3000mah 20a? Is there some sort of protection on this battery from switching cells?

What battery cells needed to replace 2Ah pack?
