Resetting Makita BL1830 Battery's Electronic System After Cell Replacement

Hello.
The cells in the BL 1830 package are protected by electronics and must not be used without it, as it may cause an explosion or fire.
I built a programmer for the processor included in them, i.e.: MC68HC908JK3
and tried to read the memory, unfortunately I got the message "68HC08 Device is responding properly, but ROM is SECURE. Specify security bytes or select IGNORE".
So you can't compare memory from a working package with memory from a non-working package. You need a batch of a working package to program the proc, or knowledge of "security bytes". Does anyone own one or the other?

So what, do you need a working battery?

If so, buy a stimulant on Allegro and how to master the error deletion system, then

you'll make a nice buck and I'll be your first customer because I have 2 broken.

I was, I corrected the misspelling. Please write more carefully in the future. Regulations point 3.1.13. /Olek II/

Hi
I have the same problem, my friend and I have about 3-4 broken batteries, we are happy to pay someone to fix them .

Hi!
I'm considering buying a whole set of cordless power tools myself and that's why I have a question for someone who was interested in batteries.
Are there any locking, monitoring electronics in the tool itself?! I know it in the charger, I know it in the battery, but is there any electronics in the screwdriver or saw itself - and I'm not talking about electronics protecting against excessive discharge.

Regards and I am asking for help

And what about you, there is no lock in the tools? They will work even on a rectifier, but they spin poorly then, they need a lot of electricity.

I did, I corrected it. /Olek II/

I took the method and charges the batteries with an 18 volt charger from an old screwdriver, probably einhel,
the batteries do not heat up and recharge well but I have a problem because after an hour the battery is charged to 20 volts like from the original charger but I have to manually disconnect the charging.
there is a whole disconnecting system in the charger, it just needs a device that will disconnect the charger relay at about 20 V.

Who would make such a simple arrangement?

THERE IS A CHEAP WAY FOR THESE BATTERIES.
It is enough to buy a laptop power supply for about PLN 30, which gives more than 20 V.
We remove all the crap from the org. chargers and a power adapter placed inside.
you also need to buy an ammeter with a voltmeter for about PLN 20.
As the battery discharges to 15 V, it charges with a current of approx. 4 A and it lasts up to 1 hour.
the electronic system in the power supply regulates everything by itself.
I've been using it for a year now and it works great.
It does not destroy the battery with a high current like the original one (9A).
You can safely leave the charging for 2 days, the electronics in the power supply disconnect when it reaches over 20 V.
.
Charges good and damaged batteries.
It is enough that the cells are functional.

So what better and cheaper for this type of devices will be Ni-Cd cells?

Hello
I see here colleagues are considering the topics of powering screwdrivers with power supplies.
It is uneconomical (high currents at full load, especially with surge).
NiCd NiMh cells are a different category (1.2v/cell, other chargers and... dimensions).
I have a question, has anyone managed to do something with these Makita BL packages ... layout. MC908JK3E (some proven interface, programmer, batch ...)???
I'm so interested in it.

Hello, I will join the topic. I have a Cordless Impact Driver BTD130F screwdriver, 14.4v li-ion BL1430 battery. A year ago, some nice guy brought me a charger with a battery to work luck wanted that there was a 12v 1.0a power supply for the router, I connected it to the chama plus to + and minus to - and I've been charging this battery for a year (charging time 80 minutes) everything works I have no problem with it.
In the UK, the price of a set of 2 batteries impact drill charger is ? 250, which is two days of work, no one goes too far into battery repair

Change the charger to an older type dewalt or bosch and you can charge any type of battery after a little demornation without spending any money

Hello...I have 4 Makita akku, BL1830 with the same problem. Does somebody find the solution for this problem with the board? I found an equivalent board but it is without balancing, and I wish to repair the original board. The fuses are ok, but not charging.

Best regards!
