Question about Ryobi Multi-Volt Battery Charger
Guru is right about the trickle charge but remember, Ryobi batteries, while very good, hate cold weather. They will not charge at all if the battery is below 32 degrees so the trickle charge with slightly discharges and recharges full batteries will not complete the recharge cycle, eventually causing dead batteries. Keep batteries in the house in the winter. The fast charge works great and youll be ready in a flash.

Ryobi NiCads loose 1% per day after 3 months the cells / battery is dead. NiCad charged sub C cell is 1.2v and should not be discharged bellow 1v. So .2v / .01 is 20 days.
To prevent NiCad memory every 20 days you should recharge your Ryobi battery.
Ryobi Li Ion Zero memory Zero charge loss. So fully charge a Ryobi Li Ion battery and remove it from the charger.

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.

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.
