Its likely the batteries will take at least several hours to fully charge, if not more. NiCad batteries are slow charging and usually need 4-6 hours for a full charge. Keep them on longer or even overnight but make sure you remove them in the morning. You will probably find the light turns green after 4-6 hours of charging. If lights stay yellow and green after 12 hours of charging, it may indicate a fault in the battery itself where it will not accept a charge.

Will the P110 charger charge a lithium ion battery


No, the P110, 18V NiCad battery charger, will not charge a 18V lithium ion battery. You need one of the dual-chemistry chargers. If you have the Ryobi ONE+ batteries, you can get the P117 charger ($30) or a charger with an extra battery (P126) from a store like Home Depot. A 6 battery charger and a 12V in-car charger are also available.

I wish that I had better news for you.

Battery not charging. Orange and Green light on charger. 18V Plus one system


The air holes on the bottom of the batteries are there for the battery to vent. Downside is, these vents can also allow moisture to get in and prevent contacts from letting the battery charge and causing the "defective" display on the charger.

I work on pool and spa equipment and I had dropped my batteries in a small puddle of water where I was working, both went dead immediately and both showed "defective" on the charger even after drying them out for a few days.

Tried using a can of air and gave each of the vent holes several shots... The batteries charged and are now working perfectly.

I'm sure even overnight condensation could be the culprit for a charger to display "Defective"

Can you charge a 18v lithium battery in a nicd charger?


Do not try this since the charging circuit for lithium batteries are different than nicad! Improper charging of lithum batteries can cause a fire.

Will a nicd charger work to charge lithium-ion batteries?


no, I would not try this. You can charge a nicd battery on a lithium-ion charger but not the other way around.

Charger not charging


Just was on a website for Ryobi drills and it states that if the yellow and green light stay on for more than 15 minutes the battery is fried. Couldn't find the link but if you do a search for Ryobi Drill 18 volt you should find the same info. It was as product review from Australia I think.

I also have a problem with the charging of Ryobi batterys. They seem to charge AOK with the green light coming on but the charge does not last at all. Not sure if the problem is with the batteries on the charger.

Makita dc1804f charger will not charge new i-mh 1834 18v battery


I think your tryiong to charge NIMH batteries oon a charger designed for Lithium Ion batteries. With all the new style batteries such as NICAD, NIMH and LI-ION, charging becomes difficult. Most chargers pre NIMH and LI-ion, were designed for NICAD's. The best advise, match your batteries with the correct charger
