The most easiest way to be sure is using multimeter. my makita battery is not taking a charge   is it t - 25290419-3h5pkc2unruv115jj1tsixdi-2-0.jpg
Set your multimeter to highest dc volt. All chargers have output voltage information written on it (Must be written as "output" value or "sec"). Measure charger's output pins (which connects to battery) and be sure measured value matches with output voltage value written on charger label. If it doesn't match each other, buy a new charger and proceed with below part.

Discharge your battery. Once you discharge battery; be sure that there is no charge at all. Charge battery for 15 min. Measure battery power with multimeter again. If there is no charge at your battery, it is dead and you need another battery.

SOURCE: makita dc1804f charger will not charge new i-mh 1834 18v battery

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

When its charging it flashes green & red and won't take a charge


If it is a Makita battery charger it means the battery has died or has an internal fault, or is too hot.
Take it out of the charger, let the battery cool down if required and try again.
If both red and green lights are flashing, try a different battery.
It might be time for a replacement battery.

Makita bl1830 charges but stays on static red light


Chargers have been known to lie about what they are indicating. Even though you say the batteries were charged only a hanful of times, they may, in fact, have expired

DC18RA battery loader is not working anymore.


Makita chargers are designed to check a battery before charging them. If both the red and green lights are flashing after you put a battery on the charger, it is reading a problem with the battery and will not charge it. It could be a bad cell, a problem with the circuit board, etc. but as long as it reads the problem it will not charge the battery.

My dc18ra makita battery charger flashes red and green lights no matter how many bateries i try


The pcb inside the battery has a microcontroller that monitor the charges and charge cycle. When the cell falls below a certain voltage, it will instruct the charger not to charge and will show with a red-green flashing light. If the battery has been tried 3 times in succession then the pcb will brick itself from the makita charger. So first replace the bad cells. There are 2 solutions at this moment: charge with a 3rd party lithium charger like the imax b6 or replace the pcb with a working one. check out my blog on http://mkbl1830.blogspot.com/

Red and green light flashing on 5 of my bl11830 battaries and they will not take a charge


If you put a battery on your charger and both red and green lights flash it is indicating that battery is defective. There may be a short in the battery or they just may be too old and worn out to charge anymore. If the charger is reading the battery as defective it will not charge the battery. The only fix is to buy new batteries.

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.

Need to know what the lights mean on a makita dc24sa charger


• When the battery cartridge is inserted, the charging light color will change from green to red and charging will begin.
The charging light will remain lit steadily during charging.
• One red charging light indicates charged condition in 0 – 80% and two red ones indicates 80 – 100%.
• With finish of charge, the charging lights will change from two red ones to two green ones.
• The charging time is as follows:
Battery B9017A, BH1220, BH1420, BH9020A: approx. 20 minutes.
Battery B2417, BH1233, BH1433, BH2420, BH9033A: approx. 30 minutes.
Battery B2430, BH2433: approx. 60 minutes.
