Makita tool restoration and repair videos: kzfaq.info/sun/PLtA1NnZlTsl68KJnD1G__p1rnMFInEZC5

I fixed my battery from your videos thanks. love the drill restoration videos aswell 👍

Enjoyed the vid and very clearly explained in live format, thanks. Now subscribed. If a cell or all need replacing, what tech spec Lith-ion ones are recommended.

Good vid, I have to repair a few of these and wanted to see the construction and testing involved. I suggest for the jumpers you could use solid bare copper wire of sufficient gauge, it is better at handling heat buildup when recharging, and coat them using a liquid electrical insulation coating, it would make for a cleaner looking and lasting repair, if you're not in a rush. Also, I agree these batteries are of poor design.

i just came to see if Makita glued their battery packs in because i want to spray my battery's bright neon pink so no bugger steals them. never expected to get a firework show haha, well done staying calm and checking for thermal runaway. i use a ammo box to store and charge my battery's (lipo) with a fire alarm inside so if they discharge i can just pick them up and chuck them out the window.

Thank you for your Video.I did it how you show.the Charger akcept de battery but then the green light is stil blinking and it goes not furder.what is now my problem??

What brand and model battery 1865o are inside makita case ?

I have a Makita BL1850 and the PCB board is not the same. where can I get the oem one since I saw on another video and they stated that there was 5 PCB style board. the one on my battery pack is larger.

That’s not a bad design, those two have been repaired before by the previous owner. Those are aftermarket PCBs, that’s why there’s no balance leads also. Cheers 👍

The oryginal 6ah battery always have a Sony vtc 6 ?

How to make spot welding or did you buy it

Do you repair faulty batteries i have 3 that no longer charge?

Cheers for showing the repair, The batteries used in these packs what volt and amp is one battery and could you use higher rated amp batteries or would that not work with the smart boards thats in the battery packs

Hey, just curious, did Makita upgrade their cell from VTC5 to VTC6 in their BL1860B?

I have a bucket full of toasted Makita batteries and I always figured they just shorted, though I have no issue putting in new cells if that is what is ultimately necessary.

Sorry, my name is LUIZ , im brasilian , what is the model of the 6 mah battery? I'm going to upgrade the 3mah battery I use. thanks

wow spent years wondering

What's the name of the screw driver and size?

This Makita battery maybe is fake，now real makita battery protection board if loss power , will lock the function.😢

That could be avoided by getting a pair of wire cutters and snipping the nickel strip ends off first thing and wear gloves if you have on a ring.👌👍💯✌️🔥🍻🎄

i noticed on my fake makita battery that the spot weld failed causing battery charging fault, how serious is it replacing just one cell? as them escooters all use 18650s cells and theres alot more than ten in them , seems a hell of a waste just for one cell

Using insulating tape in this application is a really bad idea and you're just preparing for a repeat of the original fault (melting plastic). PVC insulating tape under that joint which you then solder, and may also further, be subject to high temperature in normal usage is a really bad solution; its only mildly better than the original shrink wrap on the factory cells -which failed in normal usage. A case for Kapton Tape at least.

you could use a small strip of fibreglass sheeting as an insulator it will take a lot of heat and its a great insulator

Dude Bet that made your hart jump lol I had a lithium battery do a thermal run away in my mechanical mod` I through the mod and watched the dam battery flare up, I hope your wearing safety glasses when working on these battery packs, you only got one pair of eyes` no second chance, I damaged my eyes from getting three pieces of shared metal in them that had to be pulled out with tweezers after local ascetic drop, grinding while not wearing glasses, luckily never lost my vision only reduce it, you know how quick them batteries can react and ignite with immense force. Anyways appreciate the video `these battery packs are not cheap for a DIY person ` not so bad for persons in the trade Tax deductible lol

I have BL1840B, the same issue for board , two red lights blinking, I couldn't find the PCB board for it , what I have to do now?

Hi - I have two makita li-ion batteries that would not charge. i bought and replaced the 5 18650 batteries in each battery. When i meter the batteries i get 16volts but I cannot get my DC18SD charge to charge either. I managed to get one battery up to 18 volts by charging from a Milwaukee bat but it still wont charge! Have you any ideas on what i should do? ty very much Graham

Hi, I REALLY, REALLY, recommend that you don't undertake electrical repairs whilst wearing the metal ring and bracelet....asking for trouble!!!

im totally confused what is what.

An acquaintance of mine nearly died when he left Dewalt batteries charging overnight in his loft. The roof caught fire and as he put it the fire chased him and his family down the stairs to the front door.

I wish I could see what u was doing

What cells are inside Makita 6ah battery?

The spot welder cost more than a new battery.😢

If you have any questions leave them below. Check out my other videos for more makita repairs and restorations.

"Bad design?" They make their money on the batteries, "well designed".

A good project if you have Makita tools that still work well. However, it's also perpetuating finally leaving the trash Makita system completely.

I find it weird how Makita are making several different innards for these battery packs, this is strange, I thought that genuine Makita packs have a clear silicon over the circuit board to stop dust making a track across circuit board and shorting the thing out, Also on the sides of the circuit board you should have oval holes, if you hold just the circuit board up to the light shining a torch at the front while looking at the back of the board, You should see a fine wire leading to these oval shaped holes, But if you only see one oval with a connected wire, and not the others, then only two batteries are being monitored for over charging, this will not be a genuine Makita, all of the oval holes should each have a wire leading to them, there should be 4 oval holes in all,each one with its wire, They should also have fuse and temperature sensor, and plastic surrounding the bottom of the batteries to protect them from the battery pack being dropped. The sides should have protected insulation covering the soldered nickle plates, And the label at the back should usually have loads of info in English with all its QC control pass an its other reckoning approval trade marks , I think there are to many fraud battery packs out there and they should never be left in the house connected t the power tool,

Too slow with rambling comments. No thanks.

You need to show the batteries charging again , otherwise it's NOT fixed. So many of these videos on youtube - not charging after a "repair". See 2 coments from below ..............
