Why won't makita dc1804 charger work?

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

looks to me like a defective batterie

SOURCE: I have a li-ion Makita BL1830 18V 3.0Ah battery

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

SOURCE: hi i have a makita charger that flashes red and

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

I have to agree, I assume you have tried the the same battery on both chargers? is it possible that one charger ruined all the batteries? I wish I could offer some real help other then to say "hmm." But my best guess is that one charger ruined all the batteries. unless you use them both at the same time, then it would be hard to have them all quit at once. -
