20 Most Recent Ryobi Two 18V Lithium-Ion Batteries + Lithium-Ion Charger Upgrade Combo Pack - Page 3 Questions & Answers

That is true the One+ 18V Li-Ion battery packs will work in any One+ 18V Ryobi tool. However the Lithium ion batteries will not charge in the original P110 NiCd charger. You will need one of the the new series Ryobi One+ 18V "dual chemistry" chargers for that. The will charge both types of battery packs.

I use the Ryobi Li-Ion tools the L-I batteries will cut off when they get to a low charge level this is to protect the batteries Li-Ion batteries life span is shortened when fullt discharged so when the tool suddenly stops put the battery on charge,also if the battery has a charge indicator light for a more accurite idea of the charge (green is charged,red discharged) hold the test button on then run the tool the light may go from green to red if it does that shows the the charge is about depleted if the light stays green you have a little run time left.

make sure you put the battery in the right way and its all the way down in the charger

On the bottom of your battery there's a serial number, look at the four numbers that follow any letters, one or two if any. The first two numbers are the year the battery was made, the second two are the week it was made. If your number was 0610, it would have been made in 2006 on the 10th week, about the 2nd week in March. These numbers reflect the date the battery was actually made and rolled off the assembly line. It does not take into account how much time the battery sat in a warehouse or in a The Home Depot before you bought it.

I can't belive this you are the forth person in the last three days that is haveing a problem with these batterys the same problem with the lithium-ion RYOBI combo pack batterys. People are saying they won't hold more then 5 volts and they all got them at christmas. There has to be a big problem with the battery. Although there is no warranty on the battery it self there is a warrany on faulty workmanship and i think you may have to get in line i think this will be a big recall so file now good luck

most recommend taking the battery off the charger and you don't have to unplug the charger all the time.

This is not right. They should last much longer then that. I have one of the more expensive 18V lithium batteries (the one with the button on it that tells you if it needs charging or not) and I can use mine almost all day before it needs to be recharged. I do construction work and I use my Ryobi products almost all day. Either both batteries are bad (I don't believe that is the case) or the charger is not charging them all the way to a full charge. With this charger, you do need to make sure that you remove the batteries as soon as the green light comes on. It is not good on these batteries to stay charging after they are fully charged. You also should not leave the charger plugged in without any batteries charging.Please tell me more about the charger. When you plug in the charger, does the red light come on? When you plug in a battery, does the red light stay bright and the green light blink? Does the red light go off and the green light stay on bright when you remove it from the charger?
If the charger is not working correctly, then return it for a new one.

Batteries must be completely dead before recharging or battery life is shortened.large battery is probably defective contact Ryobi to replace battery they while probably send you new batteries for free if you tell them you are going to stop buy their products.Tell them about both batteries they will probably replace both for no charge

many chargers do that ,i think it is to let you know thy are on and need to be turned off, when not in use

Yes you can try that.

Your batteries are tired and don't put out enough amps to power your drill. They may show 18V in them on a tester and show fully charged on the charger but one or more of the cells inside are just worn out. If you got three years out of them you did extremely well. The only fix is to replace the batteries.

Did you check the charger?

If you need more help post back!
Thumbs and testimonial are welcome!

If you have a P100 NiCad battery, the charger for that will not charge the new Lithium Ion P103 or P104 batteries. You need a specialised Ryobi Lithium Ion battery charger like this one

I have used alot of battery type drills and other action tools . Ryobi is on the lower end of the market as opposed to Milwaulkee and Dewalt . But my experience with battery operated tool charging equipment is that if the light is green and it's blinking , I would say it's charging . When the light goes off or stays on . I would say it's charged . Leaving the battery or batteries in the charging unit for 24 hours will not hurt the battery . My solution here is put it in the charger , and check it 12 hours later !
