be careful over what charger you use as Li-ion batteries must not be overcharged. most have a sensor that detects the voltage and stops charging when the battery is fully charged. This circuitry is inside the charger, not the pin.

Unless you are a bit clever with electronics, better off buying a new charger than trying to fix the internal circuit on it. here is some links to info ive found.
a new Ryobi 18v li charger will charge your nicad battery but a nicad charger will not charge li-ion battery.

After looking at the manual for your charger, it looks like most of the Ryobi chargers like the P113, P114, P117, P118 will charge your battery. The connector on the battery looks the same as the P103 and P104 used here in the U.S.

First, you should know your battery is a Ni-CD / NI-Mh or Li-ion battery. If it is a Ni-CD / NI-Mh battery, please fully discharged and fully charged it to prevent "Memory effect".

If it is a Li-ion battery, please charge it before you use it.

Please keep in mind that, please fully charge a battery when you store it. And, charge it again every two months.

If your old battery is dead, you can replace it with a new one. Ryobi Power Tool Battery

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.

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.

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.

The battery isn't any good. The charger is just going through it's regular steps. (I know how it is. I just bought two Ryobi 18 volt batteries for my Ryobi cordless drill, reciprocating saw, flashlight,
trim circular saw, combo set. $60 for two batteries)
