Have the Ryobi 40 Volt battery system. Off full charge the battery ran for several hours. Now on charger, I get just red flashing or red/ green flashing. Is it the battery or the charger?

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

SOURCE: Battery Charge light flashing 4 red one green Dell Inspiron 9200

usually, its an indication that the battery is nearing the end of its useful life. you can try to use another battery to isolate it further. If the same thing happens with another battery, chances are, the mobo is failing. Flashing the BIOS can usually help with battery issues. If another battery works fine and your computer is within its first year since you bought it, you can request a replacement battery from Dell

SOURCE: when charging battery flashes red then stays on

it doesn't change to green, the solid red light means it is fully charged, there should be a legend on the front of the charger to help you with this. If it flashes real fast the battery is malfunctioning and slow flashing is charging and again solid is fully charger.

Just bought a Ruobi drill with 18V Lithium Batteries. Been chatging for over an hour. Still not charged. Just the bottom Green light stays on. Is this normal? How long does it take?


The Ryobi charger will flash green as it charges and then remain steady or slowly flashing green when fully charged. Flashing red means testing and if it remains steady or slowly flashing red it is defective.

RYOBI CHARGER RED AND GREEN FLASHING LIGHT


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.

Battery in charger overnight, red light flashing, insert battery in drill, it doesnot work. Please advise. Thanking You Bob Falzano


If only the red light is flashing then the battery is not charging at all. Ryobi identifies in the manual that batteries will not charge below 43 degress F. If your batteries and charger are in the garage in a cold climate, warm the batteries to room temp in the house and then try again. If the charge starts when the batteries are warm they will continue charging for the full cycle even in a cold area.

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.

Green and red light comes on when i put battery in charger what does that mean?


Here is the manual:
http://toolboyworld.com/eBay/Ryobi_P120/P120_566_eng.pdf

Red = quick charge
yellow = evaluating
green = charged

CHARGING A COOL BATTERY PACK
If battery pack is within normal temperature range, the red LED on charger will come on.

Red LED should remain on for approximately 1 hour then the green LED will come on. Green LED on indicates battery pack is fully charged and charger is in maintenance charge mode.

Yellow / green light will not go off when charging


Its likely the batteries will take at least several hours to fully charge, if not more. NiCad batteries are slow charging and usually need 4-6 hours for a full charge. Keep them on longer or even overnight but make sure you remove them in the morning. You will probably find the light turns green after 4-6 hours of charging. If lights stay yellow and green after 12 hours of charging, it may indicate a fault in the battery itself where it will not accept a charge.

Ryobi lithium batteries won't take charge


For others with the same problem (flashing red light won't go off)...make sure you FIRMLY PUSH the battery down onto the charger and engage the latches. Simply resting the battery on the charger will not work.
