You didn't state which model charger or tools you have so I cannot find specifics on your charger. In all the chargers I've worked with and on, if both lights are flashing it usually means the battery is being read as defective and the charger won't charge it.

SOURCE: when put on charge the green and red light flash

that usually indicates a bad battery. I would unplug the charger for a couple minutes to reset it and then try again before looking at replacing the battery. Most shops have a tester there that can tell if it is in fact bad.

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!

Alternate Red and Green flashing means bad battery. Buy a new one, or take it to a Makita Service center for replacement if it's under warranty.

Normally the yellow light indicates hot battery, but it could also mean dirty battery contacts so the heat sensor can't be read, or that the fan is clogged with dust and unable to cool the battery. The manual says let the battery cool and try again. If the yellow still flashes, it's contacts or the fan.

Problem with hitachi chargers


I live by hitachi, one of the good things about it is lowes will exchange them as long as you have a receipt and it's under 30 days. If not chargers are not very expensive, or you can send it back for repairs. I have 10 of those combo packs and never had a problem with a single one, for you to get 2 is a freak accident.

What does it mean if the red and green light are on at the same time on the charger


If the red and green lights are flashing, the charger is detecting the battey has a defect and is not safe to charge. It could be one of the cells in the battey, a short in the wiring or circuit board or bad contacts. Usually the only fix is to replace 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/

My charger is flashing red when i place the battery in it


Ridgid charger lights read as follows: Solid red; charger has power. Flashing red; charger is evaluating the battery, checking if it's cool enough to charge and if it is in chargeable condition. If the battery is hot, i.e. just came off the tool after extended use, it won't charge the battery until it cools down. Flashing red & green; the battery is defective and the charger will not charge it. Solid red & flashing green; battery is charging. Solid green; battery is full.

Hi both red and green lights are flashing and it wont charge battery bl1830 lith ion


If both lights are flashing it means the battery is defective so it won't charge it. By defective it could mean the battery is just worn out or there may be a short in the battery. If the battery is under warranty you can get it replaced at a Makita Service Center, if not you have to buy a new battery.
