Lights will not light on ryobi battery charger/cannot charge fairly new battery

sounds like defective. personally I would return it to HD for a new one. HD money back 90 days from purchase.

Completely dead batteries may cause the charger to not see any load and it wont charge them. The way around this is to put the battery on the charger with the charger unplugged. Then plug in the charger and check the lights. Keep unplugging and plugging in the charger till it catches up and stays on.

in the hand book it states that the charging period for new batteries can be up to 6 hours

Yes, the green light flashes until the battery is fully charged on Ryobi chargers. This will change to a solid green light when the battery is fully charged until the charger goes to a power-saving mode. Not all of the Ryobi chargers have a power-saving mode. However, for those that do, the green led will dim over time and then brighten and dim slowly again in this mode.

My Ryobi charger, model P113, actually has a key for the LEDs on the unit on the left of the battery port. The manual for this charger is here: https://manuals.ttigroupna.com/system/files/5495/original/P113_192_trilingual.pdf?2011 . Ryobi has many of their manuals on their site. Look up your charger/tool here: https://www.ryobitools.com/power-tools/support/manuals , Home Depot's web site also has many of these manuals on the product site for the tools that they sell.

I hope this helps.

When the battery is charged the green will be steady on and the red will go off. Flashing green is an indication that it is charging.

hope this helps?

When you insert a battery for charging, which light(s) combination do you see?. There should be red,green and yellow and different individual lights or combinations of lights mean different things. If only the red light goes on, chances are the batteries are to cold to charge. They will not charge below 32F so if your charger is in the garage, take the batteries in the house until they are room temp then try again. If you still have a problem and the unit or batteries are are less than 2 yrs old they should be be under warranty.

This is not right. They should last much longer then that. I have one of the more expensive 18V lithium batteries (the one with the button on it that tells you if it needs charging or not) and I can use mine almost all day before it needs to be recharged. I do construction work and I use my Ryobi products almost all day. Either both batteries are bad (I don't believe that is the case) or the charger is not charging them all the way to a full charge. With this charger, you do need to make sure that you remove the batteries as soon as the green light comes on. It is not good on these batteries to stay charging after they are fully charged. You also should not leave the charger plugged in without any batteries charging.Please tell me more about the charger. When you plug in the charger, does the red light come on? When you plug in a battery, does the red light stay bright and the green light blink? Does the red light go off and the green light stay on bright when you remove it from the charger?
If the charger is not working correctly, then return it for a new one.

Lithium-Ion batteries require careful charging and temperature monitoring while in the charger. Ryobi's Charging station monitors many functions and shuts off when the battery has gone through a complete charge. This is indicated by a steady Green light. Once the Charge indicator is a steady green the charger stops charging. With any battery It will slowly discharge and I don’t think the Ryobi will maintain a battery that is never removed. For example, if after a complete charge cycle if the battery was left there for 2 years and then you went to use it, it would likely be completely discharged. However if the battery charger is unplugged then plugged back in a new charge sequence would start. I lose power at my house about every 6 months or so. Once power is restored a new cycle would start and the charging cycle begins again.
Hope this helps and have a great day.

More than likely a defective battery sinse the other ones charge fine..

Either the battery is hot from use or has been in the sun, let it cool down, then try again.
