I have a brand new Ryobi kit put battery in the charger the red light goes on and the green light flashers on and off is this charging or should the green light go off until battery is charged.

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.

My Ryobi 18V One+ charger blinks green while it's charging. When the battery is fully charged, the LED goes to a solid green. However, one battery recently had a faulty cell. After several hours on the charger, the green and red LEDs both were blinking. That indicated that the battery failed late in the charging sequence. It didn't fail the initial testing by the charger. The other battery I charged that day charged fine.

The extended capacity batteries can take 12 hours to charge in my experience. The regular batteries take less time. The charge time will depend on the battery chemistry(The older NiCd batteries take longer to charge then the Lithium batteries.)

I hope this helps. Assuming you aren't dealing with a cold or hot battery or charging environment, if you have any suspicion about a faulty battery, replace it.

(Note: I have a 12V drill as well. Those batteries takes longer to charge for the same relative capacity than the 18V NiCd batteries.)

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.

sound to me like you have a bad battery, a lot of ryobi batterys don't last like they should i have had the same problem, but my battery was less than a year old and i took it back and they give me a new one.

Take it back to the store and tell them it is no good, and get a new pair of batteries, take the charger too. I had the same thing, brand new batteries, gone in weeks, they replaced them, no problem.

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.

You don't need help, you need patience. That charger is on a timer. You can probably use it now anyway. If this is helpful, please post as such. TY

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