I think your tryiong to charge NIMH batteries oon a charger designed for Lithium Ion batteries. With all the new style batteries such as NICAD, NIMH and LI-ION, charging becomes difficult. Most chargers pre NIMH and LI-ion, were designed for NICAD's. The best advise, match your batteries with the correct charger

SOURCE: 18v Lithuim Ion battery will not charge

If you have been a bad boy and managed to short the battery by using it for non-proscribed purposes, the fusible link will blow (kind of like a fuse) To fix it, open up the battery (use a Torx 10 security bit, or a small flathead in a pinch) On the battery connection nearest the spring-loaded white catch there is a small bridge of metal with a hole in the center. If this is melted you can solder it back together by sanding the two pieces and putting a glob of solder on them. This will void your warranty (duh!) and remove the battery's fuse protection, but it WILL work again. If the link is intact and nothing else is obviously wrong, you almost certainly have a bad cell. I recommend pulling out the bad cell ( it will be the one that does not read between 2.5 - 4 vdc) and replacing it with one from another dud battery- this requires some fudging and re-soldering. Or do what I did, pull the cell, toss the electronics and the short pink wire, add a cigarette lighter socket and voila! you have a portable power supply giving around 14 volts. Charge it up by wiring two cigarette lighter male ends together (check polarity , + to + (tip end) and - to -) and plug it into your car, but only while it is running or you will be charging your car battery with it! Hope that helps.

SOURCE: how can i fix my makita 18v battery

there is no fixing these batteries that i know of. they have an electronic chip in them among other electronics. the battery talks to the charger and vice versa. battery packs that can be worked on doesn't really save any money with all the aggrivation you go through.

Why is my Makita bmr102 not working off 18v battery


There could be a number of reasons for this.
The battery is flat. Charge battery and try again.
The Makita BMR102 is not turned on. Turn on.
The terminals on the battery or BMR 102 are damaged. Have you tried using another power source such as a plug pack or different type of battery.
There is an internal fault. Take to a service agent.

Why will a makita Li-ion 1.3ah battery not fit in other makita tools?


Some of the Makita 18v LXT tools require the BL1830 3.0AH battery and are designed that the 1.5AH battery will not fit.

I have a makita 6391D cordless drill with 18v ni-cd 1.3ah batteries, just had one battery and charger stolen so have to buy replacements is there any way i can convert it now to lithium batteries if


I can't find a Makita model 6391D drill but they do have a model 6390D drill that takes the 18V Ni-Cd pod battery. The tools and radio don't care what type of battery you use, only that they are 18V. However, to date, Makita does not make a Li-Ion, pod battery. All of their Li-Ion batteries are the slide-on type. Your options for that 18V tool is the 2.6ah Ni-MH battery (PN 193159-1 for a single or 194158-6 for a twin pack), the 2.0ah (PN 192827-3) and 1.3ah (PN 194107-3) Ni-Cd batteries.

One question please, I have makita cordlless


according to the schematic I saw yes you can and I think that you will be pleased with its performance, their operator manual even lists the weight of tool with this battery. Makita has a 1 year limited warranty on the Li-Ion battery that you might want to consider if you have the receipt.

Hi, I have repaired 3 Makita 18V 3Ah Li-Ion batteries recently by removing good cells from other faulty batteries. The Voltages are good now on all 3 and they charge/discharge OK on my own charger but...


Some manufacturers put some chip on their battery so it can be identified by their charger. If you use a generic battery often, it will not charge or work properly. LG does this with their phone batteries! So you have to use another charger to charge them.

Battery charger just flashes to say the battery has to cool down but will not start charging.tried another charger same thing happens but does not show that the batteries are faulty!


Unfortunately, Makita’s li-ion battery packs have a design flaw. After having the same problem with my two batteries, I took it apart and saw the problem immediately. You see each battery pack has ten li-ion battery cells and a circuit board with a memory chip witch holds the charging history of the battery pack. But that memory chip constantly draws power from 2 of the 10 batteries. The current it draws is very small but if you consider it over 6 month or more, the power drain becomes very significant. You end up with a battery pack with 8 still fully charged battery cells and 2 drained battery cells. When you put this battery pack in the charger, it detects weak battery cells, assumes they are defective and refuses to charge. To avoid this problem you should charge your battery pack often, even if you haven't used it, every two months should be ok.
I suspect that Makita doesn’t make these battery packs, they make power tools, good ones too. But Makita should definitely have a few words with their supplier before they become a liability!
