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.

see if your charger is under warranty and have it replaced..yours is bad..

battre round the wrong way?

If it's not charging and your batteries are still good then more than likely the unit is shot. You can try cleaning the contacts on the unit and your batteries and see if that helps.If you know someone with a universal charger try your batteries on that to make sure it's not them that's the problem. Check ebay for a used one at a cheap price. This is not a fix you can do unless your a techie and it's not worth sending off to Ryobi for a factory fix. i just replaced my panasonic charger for the same reason, but i had it for 10 years.

How did this happen? Did you jimmy the plug???

There is the possibility there is a fuse inside. If so, it blew when you plugged the charger in.

If not, you probably smoked it.

It may be better to replace it.

see you local ryobi dealer as this can be 2 different faults in the same unit.

your batteries have possibly developed a memory and are probably shot or it may be the charger local toolstore should be able to test them both.Which ever one is bad it will cost more to buy a charger and battery than it will to buy a new drill .whatever you do ask the shop people how to stop the battery from developing a memory or if you want to come back to me when you have them fixed up I will be happy to tell you.please let us know how you get on ,thankyou

If it is out of warranty open it up and check the fuse inside. This has happened to me several times with several brands, and it has always been the fuse. They are usually replaceable at Radio Shack or the Auto Parts Store.

Hope this helps!

Batteries retain a memory. If you only drain the battery half way and than recharge all the time it will only keep half a charge. Try running it all the way down and than recharge it, this can take some time. Let it run till it gets very very slow and almost stops, but don't go past where it stops or it will not take a new charge at all. It does not always work, but worth a try before buying a new one. Good Luck

Home Depot is the only distributor for Ryobi tools

your battery will not charge if you have used it till the point of gettig flat that the battery is warm, the battery as to cool down first. also your battery has a life on it as when you charge over and over the charge will lesten each time, so you may need to change your battery failing that your charger may be no good.

A roll of duck tape wrap around the case will work quite nicely.

I hate to say it but the battery is defective. You may be able to get a replacement from the manufacturer if you contact them.

This link should help in finding a manual. Good luck. http://powertool.manualsonline.com/manuals/mfg/ryobi/ryobi_battery_charger_product_list.html

Easy!

Just remove the screws from the housing (I had to do it this morning). There are approximately 12 screws that can removed with a flat head screw driver, all from the same side of the housing. The housing readily opens up, but be carefull, there will be some rubber strips that start to fall out. Make sure you keep these; you will need them again for the replacement battery you install. The rubber strips act as a cushion between the battery and the housing's inner ribbing; helps to reduce rattle & vibration.

Next pull the 2 electrical leads (red and black) down and off of the battery terminals, a quick **** will work well.

Lastly, your battery is 12V 8.0Ah and retails for $100 plus shipping. Mine lasted 11.5 years, but finally died (I think). You might however, want to have your battery tested to see if it really is bad, it may be a bad charger which is only $10 - $20 to replace.
