    18v Makita LXT BL1830. Problem is now that charger will not charge two of the three batteries in the kit, saying "they're broke" and yet the actual battery was still holding charge and would power the impact driver no probs. Even when completely flat, the charger will not accept these batteries. Are the batteries at fault or is the charger dodgy?

    Nice trry lasvegastech BUT even with both battery and charger cool, charger still thinks the battery is faulty.

    Similar problem - 18v Makita Lithium Ion drill, about 2 years old, 1 of the original batteries stills accepts a charge. Have gotten 4 replacements that will work for 2-5 charges and then show up as bad on the charger and it won't charge them. Home depot has exchanged them as long as the date code stamped in the top is less than a year old. Opened one up and saw a circuit board on top of the battery pack - who needs that level of complexity just to charge a battery...just more to go wrong.



    Have tried it hot or cold, batteries completely flat or still with enough charge left in them to run the drill. Same story, the charger says they're no good and refuses to charge them.



    Can you bypass the "smarts" and just apply 18v for 15 minutes? At what current rate (amps)? which terminals?

Make sure the charger is cold or keep it in a cold place, when makitas charges get hot, they will not charge.

Rebuilding makita battery instructions


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.

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.

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.

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.

Between us my son and I have 10 18 volt batteries for our Makita power tools which we use in our Carpentry work of these 10 batteries 6 have failed. I have to say the reliabillity of the Ni-cad equipment...


Join the battery collectors club. I have 25 batteries, 12 guns, I quit buying the batteries, I found it cheaper to buy the gun with new batteries and charger once a year. Cause they don't even last that long. I have tried different brands too all the same. Got batteries?? Sure do.

MAKITA LXT BL1830 18V LITHIUM-ION 3.0AH BATTERY


If the charge count on the batteries is under 300, Makita will replace them. Makita has a known defect in this battery that causes the battery to shut down before it is dead. So as of now they are exchanging ones with low use.

If they are truly defective and makita won't replace, you have to open them, find the dead cell or blown fuse, and replace. Search youtube makita battery for a video on repairing this battery. But once the red and green lights on the charger flash, the the battery can't be charged on a Makita charger -- it's been locked. So use a third party charger.

Replacement 1402 battery


I can't find the 1402 battery listed on the Makita website. What is the tool catalog number and I will find you a bettery that way. You can buy online at Makitatools.com and also they have a locator to find one locally that you can use. Let me know if you need more assistance.
