Try rotating the plug that goes into the wall. I know it sounds irrelevant but ive had the same issue and it worked for me. The positive and negative may be reversed in the dock.

My charger is flashing red & green without a battery in it. Does this mean my charger is bad and how do I get a replacement. I just purchased this and this is the first time I've tried to use it.

My charger blinks red and green but I've literally only used my chainsaw 4 times. It's less than a year old. It won't charge the battery. What could be the issue? Or can I take it back to home Depot and use the warranty? Any help will be welcome.

    Ryobi batteries will not charge when they are cold! I had the same issue both red and green lights flashing which indicates that the battery is defective which I ruled out because all 3 of my batteries wouldn't charge so then I thought the charger but also ruled out (new) so got the batteries to room temperature and then they changed

It sounds like your battery is bad. If yellow and green are on for more than 15 minutes it probably a defective battery pack. See page 8 in the manual.

I found out the probem is the battery, not the charger. The cells of the batteries build up corrosion on the terminals inside and won't charge any longer. There's a guy on ebay who sells a method of revitalizng the battery. I tried it, it works.

SOURCE: 18 volt ryobi battery charger...green & yellow lights come on wha

talked to Ryobi and they are vague. It can either mean that the battery is bad, or the charger is bad and another one that maybe the contacts of the battery are dirty or not seating fully in charger. What I would look for in this instance first unplug the charger and look into charging slot to make sure the terminals of the charger are not bent and they come out into the cavity where battery would go. If not gently pull terminal into opening and retry. Sorry I couldn't be of more assistance

Have dell d610 battery light flashes 4 times red then one green, can't unplug


I would take note of the message you are getting and buy a new battery. I believe the red flashing lights mean that one or more of the cells in the battery are dying, and it's best not to turn off alarm lights like these. Did the battery hold charge for a longer period than one hour before you started to see the flashing light warning?

Makita battery charger wont charge


If both lights on the charger are flashing it is indicating you have a bad battery and the charger will not charge the battery. The charger has circuitry that tests the battery and if it 'thinks' the battery is defective it will not attempt to charge it. The only way to verify whether it's the battery or charger is to try charging your battery on another charger or try charging another battery on your charger. Most of the time it's a bad 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 light normally means that the battery needs charging. The green flashing light can mean the battery is charging or has charged, and the same with the solid green light. Green in this case is good.

Charge the unit overnight and see what the indicator state is. It should not take more than 8 hours of charging for a Li-ion battery. Once you know what the full state light looks at, then you can tell what the charging indicator looks like.

In all cases, ensure you are using the proper charger with the unit.

Yellow and green light are on but wont charge battery?


If both lights are on and both are flashing the charger is reading the battery as defective and the charger won't charge the battery. If the Red light (yellow if plastic is faded) is on and the green is flashing the charger is trying to charge the battery. If the battery won't charge replace it.

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.

I have constant red and green flashing lights on my charger


The red and green flashing lights on a Ryobi charger is a dead battery, or defective, won't charge. I hope that is what you are talking about.

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.

Dust getting in the charger is a problem, Try blowing it out with a moisture-free dust remover, found at most any store. Green flashing means improper power, due to dust or power from the outlet, try a differant wall outlet. Red flashing means the charger or battery is to hot and must cool down before it will charge. The charger will not charge a battery if the lights are flashing. Solid Red light means it is charging and solid green light means it is charged. Plug the charger in first before putting the battery on the charger. If the charger has been droped or hit the floor the coil inside could have broke loose and dammaged the charger requiring it to be replaced.
