Rechargeable batteries are almost never worth rebuilding and never last very long when they are. In some cases, Makita being one, if the circuit board in the battery detects something wrong with the battery, it 'bricks' the battery. This is not resettable and the battery will not charge on a Makita charger. I'd be looking to get my money back from the repairman since his rebuild didn't take.

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

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.

If you have tried discharging the batteries prior to charging them already with no result and from what you describe in your post, then I would have to say the charger has issues. Go to HD or Lowes (not sure if Lowes carry Makita) but another charger and test your battery again. If you get the same fault, there is an issue other than the charger, if not you need a new charger anyway. If you get the same fault with the new charger, you can always return the new one. Short of opening up the charger and using a volt meter, this is the easiest way to test to pinpoint the real problem. I hope this helps and good luck!

For NiCd and NiMH batteries - check the battery voltage (for a good battery it is ~ 19, V); each battery contains 15 units 1.2 V each; you can test each unit after disassembling the battery case (my have 4 screws each, and the case has bottom and top parts). First charge the batteries; second, disassemble cases and check each unit voltage (shouldn't be less than 1.2 V); then take any battery tester (for AA, AAA and other batteries and accus for home usage), attach 2 long (~10 inches) wires to tester's testing contacts, and test each 1.2V unit for current - if it is in "yellow" or "red" zone - the unit is dead and needs replacement

Why does my Makita 6011D cordless drill not work when my charged battery in installed? The battery does work on my Makita saw so I know it is not the battery.


Look inside where the Battery terminals connect.
THey are flat metal springs inside the drills Battery hole.
Make sure the are not compressed down causing them not to touch the battery terminals of the battery.

ALso check the Brushes on the drills motor they may need replacing...

Can my makita bl1830 battery be repaired if it does not hold charge anymore


This battery has a known design defect that causes premature failure. The battery is still probably good, but the safety circuit n the battery spuriously locks it, due to a bug. Once locked, it won't charge in the Makita charger (flashing red and green lights). Makita knows about this problem but so far is not actively recalling the batteries. Makita will replace the pack if the charge count is under 150 (some people say 300?) regardless of warranty status, but you have to take or mail it to a Makita Service Center -- the dealers won't handle this unless it's in warranty.
http://www.makita.com/en-us/Modules/Service/ServiceCenters.aspx

If Makita won't fix it, you can try to repair it. If the red and green lights are flashing, the battery is probably locked and cannot be repaired in a way that will let it be charged in the Makita charger (but it can be charged in off brand chargers). Buy a clone charger on eBay for $60 and try it. If it charges, just use it, no repair needed.

Be aware that lithium batteries do lose capacity permanently at a rate of about 20% per year. So, 3-6 years is about the best battery life you can expect - from date of manufacture, so if it sat in the store a while that adds. Makita derates the cells to allow for some shelf life (down from 2400 Mah to 1500 Mah rating).

If the battery is weak, and only gives brief usage, you can replace some of or all of the cells in the battery. These are expensive and worth repairing. See this video:
http://www.youtube.com/watch?v=Z5taguEdlkY

If just 1 or 2 cells are weak, you can replace them with the same Sony 18650 size 2400 Mah capacity battery, green sleeve. The Sony's are not sold retail, and are hard to find other than from another Makita pack or from some laptop packs. If more are weak, you're better off just replacing all of them with new 18650 2400 Mah (or higher) batteries with tabs. Look for Tenergy or other quality brand.

Hope that helps.

I used my makita 18v 1/2" cordless drill then charged it and put it away. When I tried to use it again a month later there was no power. I tried to recharge the battery but red light would only stay on...


WOW! Count yourself very lucky. Most batteries don't last half that time. The newer battery probably has a lower amp hour rating than the first one. When replacing the battery (and you must replace it) look for the one with the HIGHEST amp hours - which is usually written on the battery or packaging. You can also ask at a Batteries Plus store if they can re-build the original battery for you- since the unit is so old, and Makita might not make replacements for your drill. You could rebuild the battery yourself,it is only 12 AA or C batteries wired together, but ni-cads can be dangerous when soldering and can explode if you slip up. Best bet is to get a new or rebuilt battery.

Makita makes two 12V Ni-Cad pod batteries: Battery 1222/2.0Ah (PN: 192598-2) and Battery 1220/1.3Ah (PN: 192681-5). Makita's universal charger (PN: DC1804) will charge any Ni-MH or Ni-Cad pod or stick battery from 7.2V to 18V.

Charger doesn't charge anymore


If you are comfortable with removing the upper half of the housing, unplug charger and remove the screws, take a look at the circiut board for a "cold" solder joint or broken component, usually the round ceramic looking piece with the copper wire around it. but look at the whole board.

Is it possible to replace the batteries in a 12v makita battery pack


Unfortunately there are no repairable parts in a battery. Once a battery is dead it's usually best to find a good recycling center for it, most The Home Depot's have one. Makita lists battery 1234 (Part #193157-5) for this tool but it's the old Ni-MH battery. I'd use battery 1222 (Part #192598-2), it's the better Ni-Cd battery.
