Was given a drill as a gift about 3yrs ago, tryed it for the first time recently. problem the charger doesn't charge the battery, had the charger checked and it is only putting out about 4b volts. How can I get a replacement charger and will it be covered under warrantly now. as mentioned was a gift and I don't have the proof of purchase. please advise.

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.)

Here is the manual for the charger - note on page 2 the meaning of the problem you describe - time to replace batteries (depends how old they are)

That being said, check the videos out, perhaps can get it to work after all for a while longer.

Take it back they should replace it. If not try pluging it in a different outlet see if that works.

Battery is shot. Replacements are $75 - $100. If its new you have a 1 yr warranty.

Directions say green light indicates that the battery is fast charging only,it does not indicate at exact point of full charge. I let my batteries charge for 12 hours for the first time charging,found out myself the same way. Try that and you will notice the difference.

You need to recycle it in the charger. do you have a button on the charger to do that with? If not try switching chargers.

How long have these 2 batteries been standing idle without being charged? Lithium ion batteries can still discharge if left for too long. There is a voltage detector which detects whether the cells are too far discharged to be safely charged again and if that occurs the circuit is broken and the batteries will be deffective in the charger.
I have had the same problem with these and other LI batteries. Answer is replace the batteries and then make sure they are given a quick charge on a regular basis. However common advice seems to be that LI's should not be kept fully charged, but just partially charged until needed, then charge them for use, especially if usage is sporadic

Just try to buy a new battery and test.If persist,change the charger. Bet the bats are dead.
