Reviving Makita BL1830 & 1430 Series Li-Ion Packs: Seeking Solutions for Battery Error

Hello.
I have a problem with LiJon packs from the MAKITA BL1830 and 1430 series (with the yellow plug at the top), which cannot be brought back to life after replacing the cells (both LEDs on the DC18 charger are flashing - battery error).
Maybe someone has already come up with an idea for these accu (interface, program, input...)
uPC MC908JK3E? Proven working.
I know there was already a topic like this here:
https://www.elektroda.pl/rtvforum/topic1868800.html
But closed and no solution to the problem yet.

In that topic it is written that the CPU charger is protected against modifications. Better buy a replacement instead of the original battery.

Hello
I know that these processors are secured, but people have open minds and many ideas on various topics (that`s why we are here).
..these substitutes unfortunately have a price advantage, but they are not suitable for charging in original DC18 fast chargers.
...so if someone could help, that would be nice.

Hello, my BL 1830 is dead, after an error it is not put back into the charger. I am looking for cells from it, maybe someone has it or it is a broken battery.

And you can`t somehow gain access to the battery from the Makita charger? If the battery is damaged, the electronics in the charger must somehow change the charge in the battery...

Hello, I had 6 of these broken ones, so I took them apart, unscrewed the charger, disconnected the + and - cable, connected them directly to the car rectifier, turned them on for 2 hours and after 2 hours the battery was charged and I did the same with each one and each one was charged.

Added after 1 [minute]:

because a new battery is a bit too expensive, I recommend this way of bypassing the security measures used by Makita

Hello, I bought a Makita BL1815 battery and I have a few questions, please give me some information

namely, will the screwdriver be more powerful with a 3 ah battery than with a 1.3 ah one? I mean the power, not the battery life?
How to care for the battery so that it lasts a long time?

Thank you in advance for any information

If you can`t get to the battery, maybe you could fool the charger. Maybe someone can check what the working battery does to the charger so that it starts charging. It would be possible to build a system into the charger that would respond instead of the battery and even stop charging after a certain time.

BL1815 and BL1830 use the same cells inside - 3.6V 1500mAh/1600mAh - in 1815 there are 5 of them connected in series, in 1830 - 10, i.e. 5 voltage sections of 2 cells connected in parallel. By connecting in parallel, you can draw more current from the entire package. The cell itself is designed for high currents - 10C (they are not the same cells as in laptops). In the 1830 package we can theoretically pull 20C - it is stronger this way.
The li-ion battery will last a long time, but you cannot forget about it for 6 months and then expect it to work like new. Cells self-discharge, if we discharge the battery and leave it for a long time, it may happen that the voltage drops below the threshold accepted by the electronics and it will no longer allow the battery to be charged, considering it damaged.

Hello, as this is my first post on the forum, I would like to say hello to everyone (Sorry for the lack of Polish characters due to the English system)

I have been following this topic for some time. I managed to repair the batteries!!!
I probably searched all sources, I had 3 broken batteries, one of which came from an older set from probably 2009. After disassembling it, I immediately noticed that the older batteries were different and the electronics were less complicated. So I took the risk of replacing the cells. Now step by step how I did it.

1. I checked individual cells in the batteries.

In one battery, all the cells were good, but despite this, something caused the battery to lock up. Either way, I had less work to do.

2. I cut off the electronics from the charge (At this stage, you can replace the broken cells).

3. I soldered the electronics from an old type of battery, connected it to the charger and to my surprise it works ;)


Unfortunately, I don`t have any old batteries anymore, so out of the 3 broken ones, I have at least one good one ;)

Below is a photo of two new and old type batteries.

Ps. Sorry about my soldering - I don`t do it for a living, the most important thing is that it works

Can you check the exact year of production of the old and new batteries?

Unfortunately no, but I will tell you more. I got another old battery and wanted to do a similar trick, but with the second battery it wasn`t so good. I`m afraid the first one is pure fluke, I`m not an expert. For me, the most important thing is that at least one works

I`m green when it comes to more advanced electronics (I can only solder a bit ) but I use practically everything from Makita for 18v, but logically thinking, if this one system works, you should unsolder it and use it as a connector for broken (repaired in terms of cells) or rather blocked batteries, because the equipment draws electricity directly from the battery, bypassing the electronic system, only each battery would have a cable output with a socket, and the electronics from the old battery connected to the charger would have a plug, or maybe I`m wrong? I have 13 out of 17 batteries that are broken and this is a problem, so I`m wondering how I can charge them with a different charger, even for each cell separately? anyone help? first of all, do I have to divide 10 cells into individual ones to determine whether it works, or is there any way with a meter?

Hello,
Gentlemen, I have the same problem, I have several batteries from 2009 and several from 2010
As my colleague wrote above, I thought of permanently connecting the system that has not yet been blocked to the charger and connecting the cells for charging with the contacts we have available, but now the question is whether it blocks after reaching too low voltage several times or based on the charging counter? or this and that?

The second option is to copy the eeprom from the working electronics and put it in the blocked ones, if it gets blocked, program it again from the file saved on the PC.

Replacing the cells with new charged ones in blocked electronics does not help, you can only use them once until they are discharged :/

I have a programmer, if someone tells me how to do it, I can play with it for education.
Regards

When it comes to counting, it is definitely there because some batteries that I have have good cells and the younger batteries that I overheated with an impact hammer have damaged cells, and in both cases they were blocked in the electronics, it is good and bad that Makita does not have the system in the equipment itself, plus this that you can charge the batteries with another charger, and the downside is that when the voltage drops, the equipment could turn itself off, which would protect the cells from breaking down. After brainstorming, I decided to buy a modeling charger with a balancer and output the outputs from each battery (2x +- and 4 to the balancer ) of course after replacing the damaged cells. The charger will cost me PLN 150-250 and the problem will be solved plus plugs and sockets, and there is definitely a need to look for another solution (if someone came up with it), but no one will admit to it, it`s a pity that Makita doesn`t make batteries with Panasonic cells!

what are Panasonic cells better at? I`m asking out of pure curiosity because I have a few replacements with these cells

I have searched almost the entire Internet for a solution, but I have not found any safe and specific solution By the way, I`m curious when someone will come up with something.

At this point I bought a replacement BL1830 and BL1430 in the store www.bto.pl. They boast that they have replacements that control each section separately. Then the system probably works on the blanching principle. And the battery is made of Panasonic cells, about which I have also heard good opinions.

I also have this replacement and it works
the problem is that I have a completely new battery, virgin one could say, and I can`t get anything out of it
The Makita service center told me that there is no such thing as a battery reset and the only way they can help me is to sell a new one. I find it incomprehensible that with an army of tens of thousands of electronics engineers in the country, no one has found a way to fix this gem. What`s more, if you had the key to this door, you could live well until retirement.

It is not a matter of thousands of engineers in Poland. Worldwide they don`t yet have a way to reset the battery. That`s why we have substitutes left for now.

There is a company that offers resetting this battery, WWW.REGENERACJAAKU.PL

I wonder if they actually do a reset, or maybe they found a way to trick the processor.

I think they are replacing the electronics board with another one.

This is what the latest version of the electronics looks like:

The elements in the green fields are covered with gel.

There have already been announcements on Allegro about battery regeneration and electronics programming

Here I found interesting information about battery repair.

The www.bto.pl store has batteries with Panasonic cells, but why did they write that you cannot use Makita DC18RA, DC18RB, DC18RC, DC18SD fast chargers because the high charging current will damage the battery.
What is wrong

Hello. I would like to buy a damaged 3ah battery for a few zlotys for my screwdriver and regenerate it. Is it worth it and is there any way to bypass the protection so that after replacing the cells I can easily charge the Makita charger?

There are electronics on auction sites that you can insert into the battery and they no longer block when the cell dies.

Is it worth regenerating yourself?

It all depends on how many cells you get. But probably not.

Hello,
And someone tells me that all you need to do is cut out the 4th pin and that`s it.
Does anyone have a diagram (or a list) of the pins of the yellow connector?
Respect

Hello

Electronic boards are available online for PLN 39 to PLN 50.
As for "cutting" the pin - someone probably meant the wire running halfway through the packaged cell - in my opinion, for testing the package and at the same time protecting it against discharge/overcharging or checking the balance of the package - thus a simple test of the symmetry of the package.

A simple way to eliminate these corporate blockages and recharge these batteries. Buy a laboratory power supply. We have regulation of charging current and voltage, and the clips can be connected to the battery. And don`t buy chargers made in Makita.

Many descriptions on the electrode show that the possibility of unlocking the electronics is unlikely. An unlocked electronics replacement can be purchased for less than PLN 30, but it is without a balancer. Charging the cells is possible directly and I use the B8 Imax universal processor charger (there are also cheaper B6 ~PLN 100). B chargers (1S-6S) have a balancer and you can connect the balancer harness to an additional socket in the battery housing (for 18V, i.e. 5S - 6 pins). If you have such a terminal, you can charge the battery completely safely, with a reasonably selected current, quickly or slowly.
In addition, the so-called chargers Modeling batteries are universal and you can charge any type of battery: Li-Ion, stick, gel and Pb for your car. You can also check their capacity or individually pick up heavily discharged cells in a package that does not want to be charged by a dedicated charger.
