thanks for this great information, will this charger work with aftermarket replacement battery packs?

[@a3sully]

This video is making a simple process way more difficult than it needs to be. Just take 2 pieces of wire and spade terminals each end and connect positive to positive and negative to negative to each battery and connect up to 30 seconds, then try to charge the bad one. May need to charge the good one fully after the 30 seconds since voltage on it goes down. May need to repeat this process several times of using good battery to shock dead battery and then putting good one back on charger. And no, the battery will not be rejected permanently after 3 times of not being able to recharge. I have used my method of shocking low voltage battery and never had an issue. Can use any 18 to 20 volt battery to do this trick. No special tools needed. You're welcome.

[@myshitonyoutube]

Really? I read it everywhere that "faulty battery" 3 times will brick the PCB. A lot of people had to toss their healthy batteries because of low voltage since the charger bricks it after 3 times they say. Update: I charged mine with a 20V 2.25Ah AC adapter to 18V then I put it in the Makita charger and fully charged it without any problem.

[@Hindrenaline]

Thank you

I been jumping my car like that everyday lol lol

[@JohnBachand]

Thumbs up if it works, it's not going to short and blow up or something is it lol. I have a few aftermarket Makita batteries that will not charge, I'm not cheap, I just wanted the smaller profile 3 amp battery which Makita doesn't make. They worked okay when they were brand new but the charger is rejecting them

[@Taiwaneverything]

Used two new batteries just a few times, then didn't use the drill for a long time. Now the batteries are rejected. This seems to be a common problem. Next time I will buy a drill with a cord.

[@LairdJ56]

Or you could learn from your mistakes. Batteries lose charge over time. Different battery chemistries have different characteristics, Google is your friend 'Lithium battery care and maintenance The chargers are designed to detect a battery by a specific voltage threshold being met, closing a gate and making the circuit connection to apply the charge... This issue applies to all batteries... laptop, phone, literally everything these days. We often leave tools in places where they get cold overnight. If you had a classic car in the garage, that wouldn't start if left for months on end in the garage either

Let you guys in to a secret I had 3 old battery in my shed for years they were dead not charging all I done was connect them to my car batterys charger obviously negative 1st left them about 2mins put on drill charger and started charging again easy peasy be lucky hope this helps a few out

[@chiefjohnson2642]

[@agpawpaw5912]

[@onlygearwarrior]

It is very shameful. I've had multiple chargers go out, ruining otherwise healthy tool sets. This video is basically taking the same steps that I did. These cheap chargers are far superior to the ones sent with the tools, and they cost much less. My makita stopped charging all batteries because of 'temperature'. There's nothing wrong with the batteries. So don't throw away your chargers when they croak, because they are still useful.

[@user-2uf2kr2c]

Hello, what about getting a small/cheap aliexpress bms board that fits and solder it to the battery contacts and connect it to the incoming current. No need to have this external charger everytime. Or what a about a set up with resistors connected to the incoming current, you only need like 4 volts Regards

This is why if you get red and green flashing like that do not put it back unless it's at least partially charged. If you try three times it will permanently rejectbthat battery = bricked!

[@sharenicethings]

You re right, besides a real hardware error within the electronic circuit this can be one option for the reject.

[@FakingANerve]

In that case, this is why one shouldn't buy these products. 🤷‍♂️

[@riyariyazen]

boss, that second option (blinking red light) means. how can i fix this problems

[@dungcukhongday5697]

makita charger has protection function.after three charging times , charger notices fail such as red and green light blinks , the circuit on battery will be locked.

[@PatriotPaulUSA]

Exactly! It is to protect the 200 lb gorilla from melting his battery, because he doesn't understand, or want to deal with cell balancing.

[@ClavinZKL]

@@PatriotPaulUSA so, if that happens to me should i throw it out or let someone fix it? Someone ran over my backpack and my cordless driver was in it and it broke when i inserted my battery in it to see if it still works it overheated the battery and now it dows the red and red blink.

[@PaintSlinger99]

I took a laptop charger and spliced in two pins. I placed the pins in to pos and negative side of the battery. I used a digital outlet timer to turn on the charger an hour/ then off an hour/ then on an hour. I did this to let the cells equalize. I ran the charger 8 total off on hours and they are running great. Not sure how or why but I have my drill again

[@ElectronPower]

Sorry, but the cells won't equalize themselves, so this could have ended badly. If you wanna go this way, just charge the package up to the point where it's normally empty (use voltmeter to check) and the original charger will probably accept it at that point (unless you have dead cells - open up the package and check that all cells are healthy, before using this method). Always watch the battery while charging this way and occasionally check for the abnormal amounts of heat. The safest one is to simply charge one cell at a time - apply a maximum of 4.2 volts (with limited current) across each cell, untill it reaches the desired voltage - say 3.7 or 4V and then let the original charger finish the work.

[@Z71Ranger]

Now put it back into the Makita charger and see if it works...

[@АрсенийБабенко-е8ю]

Only if the PCB is not already permanently locked, which it will after 3 errors.

[@xxwookey]

Good stuff. I've been doing the same thing to my packs, but decided to re-use the yellow connector and replace the PCB instead. Bit more robust, but more work. And those accucell6's are brilliant aren't they (although I am on my 3rd fan, I've used mine so much)

[@sharenicethings]

+xxwookey Thanks. You re absolutely right what you did is the logical next step and probably the best solution. I also plan to do this. And yes the charger does an amazing job with full battery control.

[@nrako]

[@pophamlarry]

Does the battery have a bad cell? Why does the makita charger refuse to charge it?

[@sharenicethings]

Obviously the batteries are healthy as shown in the video.

[@salvadordollyparton666]

Umm, no. 7.8 volts is definitely not healthy. What is obvious, is there IS a problem. Somewhere. The chargers aren't just going to reject a good battery. A 4s pack at LEAST 10v, and that is pushing it to the absolute edge. And only for Sony hybrid cells that can be pushed down that far. Sounds like you have a couple bad cells.

[@Tosnowood]

when the balance charger detected low voltage and would refuse to charge , can that be the same reason battery packs own charger wouldn't charge too? Have you attempted to charge it with low current also then trying again?

[@Swenser]

I reflowed the whole underside of board and then fiddled with the yellow wired connectors. Possible shitty connection there. I can't say for sure what part exactly was the problem but... It came good. Now accepts batteries and plays the crappy tune.

[@icebergmike27]

So is it the charger that rejects the battery or is the battery that tells the charger "reject me"

[@sharenicethings]

I think it should be a combination of both but it depends on the issue. if the circuit of the battery is broken the charger will reject it if it is unable to read/comm with it. I also read about an error storage within the battery electronics which stores errors of unsuccessful charging attempts which leads to a permanent denial of any further charging attempts. Unsuccessful charging happens even if your battery has an "undervoltage" which lets any LiIon/po charger refuse to charge it. Therefore you first have to jump start the battery by an appropriate power supply or like by any charger in NiMh mode as I have shown in the video. If you do this it s important to limit the current to avoid damage to your battery cells. Since jump starting alone often does not the do the trick I am pretty happy with my own solution provided in the video.

[@ZsOtherBrother]

If you're going to use a non-Makita charger anyway, isn't there one that can charge the battery without modifying the battery itself?

[@-_Robert_-]

He added balancing cables to get baterries equaly charged so it's same voltage at the end. This type of chargers can check capacity also. (Batteries have eeprom inside where number of charges is storred, and this way it is limited to e.g.: 1000 IDK, even with all healthy cells.)

[@jerydob6499]

I think the newer 18v li ion batteries are different , far more chips.

[@-_Robert_-]

But this easy solution will still work as good as with old ones. You just skipping all electrinic inside battery.

[@predater5017]

so is it the battery or the charger thats the problem?

[@leonvanengelen1824]

the problem is that the cells on these batteries werent balanced by the bms. the charger cant solve the problem, becouse it is trying to charge the whole set of cells in series. a terrible way of saving a buck by makita. the problem is with the battery, but to be expected with this design

[@rfayz733]

So you took a good battery and pissed it up the wall becouse of a bad charger?

[@sharenicethings]

No, the problem is the battery controller unit within the battery package.

[@karlnorman2427]

This was s copied from another guys video. The first battery you opened has the more advanced BCU board and the load balancers are already connected to the yellow port. No need to open and solder on. Also some BCU have a chip onboard that will lock out the charging capabillity so a new board is necessary. Chio is Renesas NEC and encrypted dump.

You need one for each connection between the batteries. This means on a 4 pack -> 3. Additionally you need 2 more wires for measuring the total voltage of the pack. One on positive and one on negative pole. Just search google for "lipo balancer wire" if you need more info about this.
