Question about Ryobi Two 18V Lithium-Ion Batteries + Lithium-Ion Charger Upgrade Combo Pack
Have a P110 charger for nicad battery. Just bought a lithium ion battery and plugged it into the charger. No lites on the charger illuminated. Do I need the Pii8 charger?
Lithium batteries maintain their charge for a very long period of time, so they do not need to be maintained like a NiCd. A NiCd however should be run through a complete discharge cycle and recharged to prevent the memory effect. Lithium batteries should never be completely discharged. Lithium batteries detect when the battery has discharged to the safe point and shut the battery off. Each Lithium cell in a battery charges to 4.1V so all of your 18v -20v lithium batteries will contain 5 cells (5 x 4.1 = 20.5V) connected in series for the lower power packs and the higher power packs have pairs of cells connected in series. NiCd cells are 1.2V per cell depending on the pack you can have 15 to 16 cells (15 x 1.2 = 18) or (16 x 1.2 = 19.2) Craftsman has the 19.2 Volt packs. Never try to revive a Lithium battery pack using the methods shown on YouTube to revive NiCd packs. Serious harm could result.

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.
(who has the Ryobi 12V drill and charger, a few of the 4V tools, and a number of the ONE+ 18V devices and chargers. The single chemistry battery charger is not used much any more.)

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.

Lithium-Ion batteries require careful charging and temperature monitoring while in the charger. Ryobi's Charging station monitors many functions and shuts off when the battery has gone through a complete charge. This is indicated by a steady Green light. Once the Charge indicator is a steady green the charger stops charging. With any battery It will slowly discharge and I don’t think the Ryobi will maintain a battery that is never removed. For example, if after a complete charge cycle if the battery was left there for 2 years and then you went to use it, it would likely be completely discharged. However if the battery charger is unplugged then plugged back in a new charge sequence would start. I lose power at my house about every 6 months or so. Once power is restored a new cycle would start and the charging cycle begins again.
Hope this helps and have a great day.

Testimonial: "This is the best answer I received! Thanks!"
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.

SOURCE: can I use the ryobi
No. The P110 is for NiCad batteries. Any of the Li-Ion chargers like the P113 are backwards compatible and can charge either but do not try to charge Li_ion batteries in a NiCad or NiHi charger.
