You are probably skeptical that maybe the directions telling you not to do that are just intended to get you to buy more stuff. We've all been there. However, Li-ion batteries are very different from nicads. Used incorrectly they can be downright dangerous. So, no, don't try using the nicad charger for the Li-Ion batteries.

No, just return it, for the money they should give you one that works. It is common to get a defective Ryobi 18v lithium battery. I've had 2 out of 7 purchased that wouldn't hold a charge. But when you get a good one they work awesome!

Ok ... and who do you trust? Is it charging your batteries?

Your batatery and/or charger have no reason to deceive you, my friend.

Same Thing just happened to me, I bought a painter with two batteries. One battery did not charge. Took the kit back, got new kit. Two batteries will not charge.Charged them for additional 12 hrs, still no good. Returning them to Home Depot.

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.

I was recently told that the lithium ion does not like cold temperatures so you may need to bring the batteries and charge into a warm location and wait until they reach a warm temperature and then charge them.

try and unplug the charger for a couple minutes and let it reset and the insert the battery. It might work, I have a LI-ION charger from a different MFR that does the same thing and it works for me If it doesn't work I would suggest calling ROBI direct at 1-800-525-2579 and speak with their tech department. They don't provide much online help.

Nicads and Nmh batteries can be charged, but Lithium is a different process and using NiCad charger will not properly charge the batteries and also put them at risk of damage.

Thanks for usig Fixya

there should be a warranty I would think no matter where you bought it. There are codes on the tool to tell them when manufactured. I would contact a service center or repair service again and push the point. If you still have a problem let me know and I will try and get a number at Ryobi itself for you.

When it is brand new only. If charged overnight and still does not last take back to purchase place and have them test battery..then make them replace it if it is bad...:)

Yes you can that is an automatic charger when it is fully charged it shuts down the charging portion but keeps the charged light lit however this does not effect the battery.

The battery isn't any good. The charger is just going through it's regular steps. (I know how it is. I just bought two Ryobi 18 volt batteries for my Ryobi cordless drill, reciprocating saw, flashlight,
trim circular saw, combo set. $60 for two batteries)

Is this an old battery? Batteries can fail and not charge after a lot of use. If it's new, run it all the way dead, then try to recharge .

If the battery will take apart the remove the screws and split the casing. Leave it somewhere warm and dry for several days...

I read online that someone fixed this problem by rotating the plug in the wall. Another person said that the terminals in the charger were a bit corroded and possibly bent so they caused the lights to flash.
