Question about Makita Drills
Placed a battery to be charged in the charger and both the red and green lights are flashing
The most easiest way to be sure is using multimeter.
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.

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

Sorry Mate your battery is dead...
The makita lithium batterys dont like getting worked hard quickly.
There is a chip in them that recognice each battery to each specific charger. Try another charger. This has not worked for me. Try anyway

there is a problem with the charger and given the age I would take it to an authorized dealer and get a replacement. If you give me your general area I will try and locate one close to you. Please before voting if you need more assistance let me know. Thank you
